Develop and Deploy Microservices with JHipster

JHipster is one of those open-source projects you stumble upon and immediately think, “Of course!” It combines three very successful frameworks in web development: Bootstrap, Angular, and Spring Boot. Bootstrap was one of the first dominant web-component frameworks. Its largest appeal was that it only required a bit of HTML and it worked! Bootstrap showed many in the Java community how to develop components for the web. It leveled the playing field in HTML/CSS development, much like Apple’s Human Interface Guidelines did for iOS apps.

At its core, JHipster is a Yeoman generator. Yeoman is a code generator that you run with a yo command to generate complete applications or useful pieces of an application. Yeoman generators promote what the Yeoman team calls the “Yeoman workflow”. This is an opinionated client-side stack of tools that can help developers quickly build beautiful web applications. It takes care of providing everything needed to get working without the normal pains associated with a manual setup.

This tutorial shows you how to build a microservices architecture with JHipster 4.5.4. You’ll generate a gateway (powered by Netflix Zuul and the JHipster Gateway), a microservice (that talks to MongoDB), and use Docker Compose to make sure it all runs locally. Then you’ll deploy it to Minikube and Google Cloud using Kubernetes.

Install JHipster 4

The Installing JHipster instructions show you all the tools you’ll need to use a released version of JHipster.

  1. Install Java 8 from Oracle
  2. Install Git from
  3. Install Node.js from (I used Node 6.11.0 to write this article)
  4. Install Yarn using the Yarn installation instructions
  5. Run the following command to install Yeoman

     yarn global add yo
  6. Run the following command to install JHipster

     yarn global add generator-jhipster

Microservices with JHipster

To build a microservices architecture with JHipster, you’ll need to generate two applications and clone another.

  • Generate a gateway
  • Generate a microservice
  • Clone the JHipster Registry

You can see how these components fit in the diagram below.

JHipster Microservices Architecture

To see what’s happening inside your applications, you can use the JHipster Console, a monitoring tool based on the ELK Stack. I’ll cover JHipster Console in the Docker Compose section.

Create an API Gateway

To create a microservices project, open a terminal window and create a jhipster-microservices-example directory. Then create a blog directory for the gateway application.

mkdir -p jhipster-microservices-example/blog

In JHipster terms, a gateway is a normal JHipster application. This means you can develop it like a monolith, but it also acts as the entrance to your microservices. More specifically, it provides HTTP routing and load balancing, quality of service, security, and API documentation for all microservices.

In a terminal, navigate to the blog directory and run jhipster.

cd jhipster-microservices-example/blog

JHipster prompts you with many questions about the type of application you want to generate and what features you’d like to include. Create the blog application with the following settings:

  • Application type: Microservice gateway
  • Base name of the application: blog
  • Port: 8080
  • Default package name:
  • JHipster Registry: Yes
  • Type of authentication: JWT
  • Type of database: SQL
  • Production database: PostgreSQL
  • Development database: H2 with disk-based persistence
  • Maven or Gradle: Maven
  • Other technologies: Elasticsearch
  • Client framework: Angular 4
  • Sass for CSS: Yes
  • Internationalization support: Yes
  • Native language: English
  • Additional languages: Spanish
  • Testing frameworks: Gatling, Protractor
  • Install other generators from the JHipster Marketplace: No

Generating the gateway

If you’d like to use the same settings I did, you can place the following .yo-rc.json file in the blog directory and run jhipster in it. You won’t be prompted to answer any questions because the answers are already in .yo-rc.json.

  "generator-jhipster": {
    "promptValues": {
      "packageName": "",
      "nativeLanguage": "en"
    "jhipsterVersion": "4.5.4",
    "baseName": "blog",
    "packageName": "",
    "packageFolder": "org/jhipster/blog",
    "serverPort": "8080",
    "authenticationType": "jwt",
    "hibernateCache": "hazelcast",
    "clusteredHttpSession": false,
    "websocket": false,
    "databaseType": "sql",
    "devDatabaseType": "h2Disk",
    "prodDatabaseType": "postgresql",
    "searchEngine": "elasticsearch",
    "messageBroker": false,
    "serviceDiscoveryType": "eureka",
    "buildTool": "maven",
    "enableSocialSignIn": false,
    "jwtSecretKey": "f7450a034a7251b3d201cf5139852f9adf69c2d1",
    "clientFramework": "angular2",
    "useSass": true,
    "clientPackageManager": "yarn",
    "applicationType": "gateway",
    "testFrameworks": [
    "jhiPrefix": "jhi",
    "enableTranslation": true,
    "nativeLanguage": "en",
    "languages": [

The project creation process will take a couple of minutes to run, depending on your internet connection speed. When it’s finished, you should see output like this:

Generation success

Before you can run this project, you’ll need to download and start an instance of the JHipster Registry. Run the following commands in the jhipster-microservices-example directory.

git clone registry
cd registry && yarn && ./mvnw

The JHipster Registry is built on Spring Cloud Netflix and Spring Cloud Config. Patterns provided by Spring Cloud Netflix include Service Discovery (Eureka), Circuit Breaker (Hystrix), Intelligent Routing (Zuul), and Client Side Load Balancing (Ribbon).

In a previous post, I showed you how you can use Eureka for service discovery. JHipster Registry is a Eureka server, a Spring Cloud Config server, as well as an administration server. It includes dashboards to monitor and manage your JHipster applications.

JHipster Registry starts on port 8761 by default.

JHipster Registry

In a new terminal window, navigate to jhipster-microservices-example/blog and run ./mvnw to start the blog application and open http://localhost:8080 in your favorite browser. The first thing you’ll notice is a dapper-looking fellow explaining how you can sign in or register.

Default homepage

Sign in with username admin and password admin and you’ll have access to navigate through the Administration section. This section offers nice looking UIs on top of some Spring Boot’s many monitoring and configuration features. It also allows you to administer users:

User management

It gives you insights into Application and JVM metrics:

Application and JVM Metrics

And it allows you to see the Swagger docs associated with its API.

Swagger docs

You can run the following command (in a separate terminal window) to start the Protractor tests and confirm everything is working properly.

yarn e2e

At this point, it’s a good idea to check your project into Git so you can easily see what changes are made going forward.

git init
git add .
git commit -m "Gateway created"

Shut down your blog application before proceeding to the next section.

Generate Entities

For each entity you want to create, you will need:

  • A database table
  • A Liquibase change set
  • A JPA entity class
  • A Spring Data JpaRepository interface
  • A Spring MVC RestController class
  • An Angular model, state, component, dialog components, service
  • Several HTML pages for each component

Also, you should have integration tests to verify that everything works and performance tests to verify that it runs fast. In an ideal world, you’d also have unit tests and integration tests for your Angular code.

The good news is JHipster can generate all of this code for you, including integration tests and performance tests. In addition, if you have entities with relationships, it will generate the necessary schema to support them (with foreign keys), and the TypeScript and HTML code to manage them. You can also set up validation to require certain fields, as well as control their length.

JHipster supports several methods of code generation. The first uses its entity sub-generator. The entity sub-generator is a command-line tool that prompts you with questions which you answer. JDL-Studio is a browser-based tool for defining your domain model with JHipster Domain Language (JDL). Finally, JHipster-UML is an option for those that like UML. Supported UML editors include Modelio, UML Designer, GenMyModel, and Visual Paradigm. I like the visual nature of JDL-Studio, so I’ll use it for this project.

Below is the entity diagram and JDL code needed to generate a simple blog with blogs, entries, and tags.

Blog entity diagram

You can click on this URL, or copy/paste the contents of the file below to your hard drive if you’d like to follow along.

entity Blog {
    name String required minlength(3),
    handle String required minlength(2)

entity Entry {
    title String required,
    content TextBlob required,
    date ZonedDateTime required

entity Tag {
    name String required minlength(2)

relationship ManyToOne {
    Blog{user(login)} to User,
    Entry{blog(name)} to Blog

relationship ManyToMany {
    Entry{tag(name)} to Tag{entry}

paginate Entry, Tag with infinite-scroll

Run the following command (in the blog directory) to import this file. Running this command will generate entities, tests, and a UI.

jhipster import-jdl ~/Downloads/jhipster-jdl.jh

You’ll be prompted to overwrite src/main/resources/config/liquibase/master.xml. Type a to overwrite this file, as well as others.

Start the application with /.mvnw and run yarn start (in another window) to view the UI for the generated entities. Create a couple of blogs for the existing admin and user users, as well as a few blog entries.



From these screenshots, you can see that users can see each other’s data, and modify it.

Now, check your generated entities into Git.

git init
git add .
git commit -m "Entities generated"

Add Business Logic

TIP: To configure an IDE with your JHipster project, see Configuring your IDE. Instructions exist for Eclipse, IntelliJ IDEA, Visual Studio Code, and NetBeans.

To add more security around blogs and entries, open and find the getAllBlogs() method. Change the following line:

List<Blog> blogs = blogRepository.findAll();


List<Blog> blogs = blogRepository.findByUserIsCurrentUser();

The findByUserIsCurrentUser() method is generated by JHipster in the BlogRepository class and allows limiting results by the current user.

public interface BlogRepository extends JpaRepository<Blog,Long> {

    @Query("select blog from Blog blog where blog.user.login = ?#{principal.username}")
    List<Blog> findByUserIsCurrentUser();


After making this change, re-compiling BlogResource should trigger a restart of the application thanks to Spring Boot’s Developer tools. If you navigate to http://localhost:9000/blogs, you should only see the blog for the current user.

Admin's blog

To add this same logic for entries, open and find the getAllEntries() method. Change the following line:

Page<Entry> page = entryRepository.findAll(pageable);


Page<Entry> page = entryRepository.findByBlogUserLoginOrderByDateDesc(SecurityUtils.getCurrentUserLogin(), pageable);

Using your IDE, create this method in the EntryRepository class. It should look as follows:

Page<Entry> findByBlogUserLoginOrderByDateDesc(String currentUserLogin, Pageable pageable);

Recompile both changed classes and verify that the user user only sees the entries you created for them.

User's entries

After making this changes, commit them to Git.

git add .
git commit -m "Add business logic"

You might notice that this application doesn’t look like a blog and it doesn’t allow HTML in the content field.

Make UI Enhancements

When doing UI development on a JHipster-generated application, it’s nice to see your changes as soon as you save a file. JHipster 4 uses Browsersync and webpack to power this feature. You enable this previously by running the following command in the blog directory.

yarn start

In this section, you’ll change the following:

  1. Change the rendered content field to display HTML
  2. Change the list of entries to look like a blog

Allow HTML

If you enter HTML in the content field of a blog entry, you’ll notice it’s escaped on the list screen.

Escaped HTML

To change this behavior, open entry.component.html and change the following line:



<td [innerHTML]="entry.content"></td>

After making this change, you’ll see that the HTML is no longer escaped.

HTML in entries

Improve the layout

To make the list of entries look like a blog, replace <div class="table-responsive"> with HTML, so it uses a stacked layout in a single column.

<div class="table-responsive" *ngIf="entries">
    <div infinite-scroll (scrolled)="loadPage(page + 1)" [infiniteScrollDisabled]="page >= links['last']"
        <div *ngFor="let entry of entries; trackBy: trackId">
            <small>Posted on {{ | date: 'short'}} by {{}}</small>
            <div [innerHTML]="entry.content"></div>
            <div class="btn-group mb-4 mt-1">
                <button type="submit"
                        [routerLink]="['/', { outlets: { popup: 'entry/'+ + '/edit'} }]"
                        class="btn btn-primary btn-sm">
                    <span class="fa fa-pencil"></span>
                    <span class="hidden-md-down" jhiTranslate="entity.action.edit">Edit</span>
                <button type="submit"
                        [routerLink]="['/', { outlets: { popup: 'entry/'+ + '/delete'} }]"
                        class="btn btn-danger btn-sm">
                    <span class="fa fa-remove"></span>
                    <span class="hidden-md-down" jhiTranslate="entity.action.delete">Delete</span>

Now it looks more like a regular blog!

Blog entries

Commit all your changes to Git.

git add .
git commit -m "UI enhancements"

Create a Microservice

To generate a store microservice, open a terminal window and navigate to the jhipster-microservices-example directory. Create a store directory and run jhipster in it.

cd ~/jhipster-microservices-example
mkdir store
cd store

Use the following settings to generate a microservice that uses MongoDB for its database.

  • Application type: Microservice application
  • Base name of the application: store
  • Port: 8081
  • Default package name:
  • Type of authentication: JWT
  • Use JHipster Registry: Yes
  • Type of database: MongoDB
  • Maven or Gradle: Maven
  • Other technologies: None
  • Internationalization support: Yes
  • Native language: English
  • Additional languages: Spanish
  • Testing frameworks: Gatling
  • Install other generators from the JHipster Marketplace: No

Generating the microservice

The .yo-rc.json created by this process is as follows:

  "generator-jhipster": {
    "promptValues": {
      "packageName": "",
      "nativeLanguage": "en"
    "jhipsterVersion": "4.5.4",
    "baseName": "store",
    "packageName": "",
    "packageFolder": "org/jhipster/store",
    "serverPort": "8081",
    "authenticationType": "jwt",
    "hibernateCache": "no",
    "clusteredHttpSession": false,
    "websocket": false,
    "databaseType": "mongodb",
    "devDatabaseType": "mongodb",
    "prodDatabaseType": "mongodb",
    "searchEngine": false,
    "messageBroker": false,
    "serviceDiscoveryType": "eureka",
    "buildTool": "maven",
    "enableSocialSignIn": false,
    "jwtSecretKey": "ea21b5b635606be4d7937e29926166e0ee56abb1",
    "enableTranslation": true,
    "applicationType": "microservice",
    "testFrameworks": [
    "jhiPrefix": "jhi",
    "skipClient": true,
    "skipUserManagement": true,
    "nativeLanguage": "en",
    "languages": [
    "clientPackageManager": "yarn"

Commit your changes to Git. It’s always a good idea to do this before generating entities.

cd ~/jhipster-microservices-example/
git add store
git commit -m "Generate store application"

Generate Product Entity

Create a product entity by running the following command in the store directory.

jhipster entity product

Use the following answers for the questions asked:

  • Do you want to add a field to your entity? Yes
  • What is the name of your field? name
  • What is the type of your field? String
  • Do you want to add validation rules to your field? Yes
  • Which validation rules do you want to add? Required

  • Do you want to add a field to your entity? Yes
  • What is the name of your field? price
  • What is the type of your field? BigDecimal
  • Do you want to add validation rules to your field? Yes
  • Which validation rules do you want to add? Required

  • Do you want to add a field to your entity? No

  • Do you want to use a Data Transfer Object (DTO)? No
  • Do you want to use separate service class for your business logic? No
  • Do you want pagination on your entity? Yes, with pagination links

Your terminal should look similar to the following after you’ve answered all these questions.

Generating product entity

Generate UI for Product Entity

A microservice only contains the server-side code for the entities it contains. To generate an Angular UI for the product, navigate to the blog directory and run the same command.

jhipster entity product

Use the following answers to the questions asked:

  • Do you want to generate this entity from an existing microservice? Yes
  • Enter the path to the microservice root directory: ../store
  • Do you want to update the entity? Yes

A visual of these questions and answers is in the screenshot below.

Generating product entity UI

Commit your changes to Git.

cd ~/jhipster-microservices-example
git add .
git commit -m "Add product entity"

At this point, you should be able to verify everything works by starting the registry, blog, store, and MongoDB. You can run MongoDB using Docker Compose with the following command in the store directory. You’ll need to have Docker installed and running for this command to work.

docker-compose -f src/main/docker/mongodb.yml up

The Docker Compose section shows how you can run all your services using Docker.

Navigate to http://localhost:8080, log in with admin/admin, and go to Entities > Product. You should be able to add a product and see that it has a MongoDB identifier.

Add Product

Build for Production

A JHipster application can be deployed anywhere a Spring Boot application can be deployed. Its Angular client is bundled inside its JAR files. JHipster ships with support for deploying to Cloud Foundry, Heroku, Kubernetes, AWS, and AWS with Boxfuse.

When you prepare a JHipster application for production, it’s recommended to use the pre-configured “production” profile. With Maven, you can package your application by specifying the prod profile when building.

./mvnw -Pprod package

The production profile is used to build an optimized JavaScript client. You can invoke this using webpack by running yarn run webpack:prod. The production profile also configures gzip compression with a servlet filter, cache headers, and monitoring via Metrics. If you have a Graphite server configured in your application-prod.yml file, your application will automatically send metrics data to it.

When you run this command in the blog application, you’ll likely get a test failure.

Results :

Failed tests:
  BlogResourceIntTest.getAllBlogs:184 Status expected:<200> but was:<500>

Tests run: 157, Failures: 1, Errors: 0, Skipped: 0

The reason this happens is shown in a stack trace in your terminal.

2017-06-19 10:29:17.288 ERROR 4168 --- [           main]  
: An unexpected error occured: Authentication object cannot be null; nested exception is 
java.lang.IllegalArgumentException: Authentication object cannot be null
2017-06-19 10:29:17.472 ERROR 4168 --- [           main]        
: Entity processing failed, A new blog cannot already have an ID

To fix this, you can use Spring Security Test’s @WithMockUser. Open and inject UserRepository as a dependency.

private UserRepository userRepository;

Change the createEntity() method, so it’s not static and uses the userRepository to set a user on the blog entity.

public Blog createEntity(EntityManager em) {
    Blog blog = new Blog()
    return blog;

Add @WithMockUser to the getAllBlogs() method.

public void getAllBlogs() throws Exception {

Commit your changes to Git.

git add .
git commit -m "Fix tests"

After fixing this test, you should be able to run ./mvnw -Pprod package without any failures. You might notice that this does take quite some time, mostly due to the Webpack build and optimizations. Below is the output from a Mid 2015 MacBook Pro with 16GB of RAM and JAVA_OPTS set to -Xmx2048m.

Deploy to the Cloud

What good is a microservices architecture if it’s not deployed to a PaaS (Platform as a Service)?! PaaS providers are also known as “the cloud”, and allow you to deploy and scale microservices as needed. Docker provides a mechanism to “package” your applications as an entire bundle. A Docker container includes the operating system and services needed to run your application. Often, Docker containers are used for the individual components of your architecture. For example, you’ll have a Docker container for each app, as well as one for PostgreSQL, MongoDB, and Elasticsearch.

To complete this section, you’ll need to install Docker.

NOTE: If you’re not on Mac or Windows, you may need to install Docker Compose as well.

Run with Docker Compose

Docker Compose is a tool for defining and running multi-container Docker applications. With Compose, you can create and start all the components of your application with a single command.

  1. Make sure Docker is running
  2. Build Docker images for the blog and store applications by running the following command in both directories:

     ./mvnw package -Pprod docker:build
  3. Using your terminal, navigate to the root directory of your project, and create a docker directory. Then run the JHipster Docker Compose sub-generator in it.

     jhipster docker-compose
    • Application type: Microservice application
    • Root directory of your microservices: ../
    • Applications to include: blog and store
    • Applications with clustered databases: None
    • Set up monitoring: JHipster Console with ELK/Zipkin
    • The admin password for the JHipster Registry: admin

    Generating Docker

  4. Run docker-compose up to run all your services and see the logs in the same window. Add -d if you want to run them as a daemon

  5. Use Kitematic to view the ports and logs for the services deployed


You can view the JHipster Registry at http://localhost:8761.

To produce data for the JHipster Console to display, run some Gatling tests in the blog app.

./mvnw gatling:execute

These simulations can take a while (> 10m) to complete. When they’re finished, you can view their pretty reports.

Gatling Results

You can see the JHipster Console at http://localhost:5601. Navigate to Dashboards > Open to display some pre-built dashboards for the JVM, logs, metrics, microservices, and performance. The screenshots below show you what some of these look like.

JVM Dashboard Metrics Dashboard
Microservices Dashboard Performance Dashboard

To save your changes for Docker Compose, commit your changes to Git.

git add .
git commit -m "Add Docker Compose"

Run with Kubernetes and Minikube

Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It was developed at Google over the last 16 years and was internally called Borg. To deploy Docker containers with Kubernetes, you set up a cluster, then deploy to it. The context can be local (with Minikube), or remote (e.g. a Raspberry Pi cluster, Google Cloud, AWS, OpenShift, etc.).

Follow the steps below to use Kubernetes to deploy to a local cluster.

  1. Install kubectl, VirtualBox and Minikube
  2. Start Minikube using minikube start
  3. To be able to work with the docker daemon, run the following command in your terminal:

    eval $(minikube docker-env)
  4. Create Docker images of the blog and store applications:

     ./mvnw package -Pprod docker:build
  5. Using your terminal, navigate to the root directory of your project, and create a kubernetes directory. Then run the JHipster Kubernetes sub-generator in it.

     jhipster kubernetes
    • Application type: Microservice application
    • Root directory of your microservices: ../
    • Applications to include: blog and store
    • The admin password for the JHipster Registry: admin
    • Kubernetes namespace: default
    • Base Docker repository name (e.g. mraible): <your-docker-hub-username>
    • Command to push Docker image to repository: docker push

    Generating Kubernetes

  6. Run the following commands to tag your Docker images. The Kubernetes sub-generator says to run docker push as well, but you don’t need that for a Minikube deployment.

     docker image tag blog mraible/blog
     docker image tag store mraible/store
  7. Run the following commands in the kubernetes directory to deploy to Minikube.

     kubectl apply -f registry
     kubectl apply -f blog
     kubectl apply -f store

    The deployment process can take several minutes to complete. Run minikube dashboard to see the deployed containers.

    Minikube Dashboard

    You can also run kubectl get po -o wide --watch to see the status of each pod.

  8. Run minikube service blog to view the blog application. You should be able to login and add blogs, entries, and products.

To remove all deployed containers, run the following command:

kubectl delete deployment --all

To stop Minikube, run minikube stop.

To save your changes for Kubernetes, commit your changes to Git from the top-level directory.

git add .
git commit -m "Kubernetes"

Deploy to Google Cloud

Google Cloud is a PaaS that’s built on Google’s core infrastructure. It’s one of the easiest providers to support Kubernetes. Complete the steps below to deploy your hip microservices to Google Cloud. If you completed the Minikube section above, open a new terminal window to reset things.

  1. Create a Google Cloud project at
  2. Navigate to to initialize the Container Engine for your project
  3. Install Google Cloud SDK and set project using:

    gcloud config set project <project-name>
  4. Create a cluster:

    gcloud container clusters create <cluster-name> --machine-type=n1-standard-2 --scopes cloud-platform --zone us-west1-a

    To see a list of possible zones, run gcloud compute zones list.

  5. Push the blog and store docker images to Docker Hub. You will need to create an account and run docker login to push your images. The images can be run from any directory.

     docker image tag blog mraible/blog
     docker push mraible/blog
     docker image tag store mraible/store
     docker push mraible/store
  6. Run kubectl commands to deploy

     kubectl apply -f registry
     kubectl apply -f blog
     kubectl apply -f store
  7. Use port-forwarding to see the registry app locally

    kubectl port-forward jhipster-registry-0 8761:8761
  8. Run kubectl get service blog to get the external IP of the blog application on Google Cloud. Open http://<external-ip>:8080 to view your running application and verify everything works.

  9. Scale microservice apps as needed with kubectl:

    kubectl scale --replicas=3 deployment/store

Did you get everything working? If so, you rock! You’ve built a production-ready microservices scaffold for your application with JHipster!

Issues Found

While creating this example, I ran into a few issues.

  1. Alert translations not resolved in the gateway for microservice entities. The workaround is to open the src/main/webapp/i18n/*/product.json files and move the keys from storeApp to blogApp. See issue #5960 for more information.

  2. In production mode, new entries don’t show in the list. The logs have an error like the following:

     2017-06-19 18:08:06.930 ERROR 17597 --- [ XNIO-2 task-62]  : 
     An unexpected error occured: Unable to access lob stream; nested exception is org.hibernate.HibernateException: 
     Unable to access lob stream

    This is a known issue with PostgreSQL. Adding @Transactional to the class definition solved this problem.

  3. When running everything in Minikube, adding new products fails. Upgrading to JHipster Registry 3.0.2 solved this issue. See this commit to see how to upgrade.

Source Code and Screencast

The source code for this tutorial is available on GitHub. See its README if you simply want to clone the project and run it. Or, you can watch a screencast of building microservices with JHipster and deploying to Google Cloud.

I hope you’ve enjoyed learning how JHipster can help you develop hip microservice architectures! It’s a nifty project, with an easy-to-use entity generator, a beautiful UI, and many Spring Boot best-practice patterns. If you have features you’d like to add or if you’d like to refine existing features, you can watch the project on GitHub and help with its development and support. We’re always looking for help!

If you have questions about JHipster, please hit me up on Twitter or post a question to Stack Overflow with the “jhipster” tag.
