It appears you’re reading this document on GitHub. If you want a prettier view, install Asciidoctor.js Live Preview for Chrome, then view the raw document. Another option is to use the DocGist view. |
If you’d like to get right to it, the source code for this application is on GitHub. To run the app, use ./mvnw
. To test it, run ./mvnw verify
. To run its end-to-end tests, run ./mvnw
in one terminal and npm run e2e
in another.
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 most substantial appeal was that it only required a bit of HTML, and it worked! All the efforts we made in the Java community to develop web components were shown a better path by Bootstrap. It leveled the playing field in HTML/CSS development, much like Apple’s Human Interface Guidelines did for iOS apps.
Julien Dubois started JHipster in October 2013 (Julien’s first commit was on October 21, 2013). The first public release (version 0.3.1) launched on December 7, 2013. Since then, the project has had 250 releases! It is an open-source, Apache 2.0-licensed project on GitHub. It has a core team of 30 developers and over 700 contributors. You can find its homepage at www.jhipster.tech. If you look at the project on GitHub, you can see it’s mostly written in TypeScript (57%), Java (18%), and JavaScript (13%).
JHipster 8 is the same JHipster many developers know and love, with a couple of bright and shiny new features: namely Spring Boot 3.2, Angular 17, Vue 3, and Java 21 support.
The Installing JHipster instructions show you all the tools you’ll need to use a released version of JHipster.
-
Install Java 17 using SDKMAN!
-
Install Git from https://git-scm.com.
-
Install Node.js from http://nodejs.org. JHipster recommends using Node 20.
-
Run the following command to install JHipster.
npm i -g generator-jhipster@8
To create a project, open a terminal window and create a directory. For example, mkdir blog
. Navigate into the directory and run jhipster
. You’ll be prompted to answer several questions about the type of application you want to create and what features you’d like to include. The screenshot below shows the choices I made to create a simple blog application with Angular.
If you’d like to create the same application I did, you can place the following .yo-rc.json
file in an empty directory and run jhipster
in it. You won’t be prompted to answer any questions because this file provides the answers.

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 the following.
Run ./mvnw
to start the application and navigate to http://localhost:8080 in your favorite browser. The first thing you’ll notice is a hipster explaining how you can sign in or register.
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:
Administration > Metrics gives you insights into Application and JVM metrics:
Administration > API allows you to see the Swagger docs associated with its API.
You can run the following command (in a separate terminal window) to run the Cypress tests and confirm everything is working correctly.
npm run e2e
For each entity you want to create, you will need:
-
a database table;
-
a Liquibase changeset;
-
a JPA entity class;
-
a Spring Data
JpaRepository
interface; -
a Spring MVC
RestController
class; -
an Angular list component, edit component, service; and
-
several HTML pages for each component.
Also, you should have integration tests to verify that everything works and performance tests to confirm 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. If you have entities with relationships, it will create 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 that you answer.
JDL-Studio is a browser-based tool for defining your domain model with JHipster Domain Language (JDL). I like the visual nature of JDL-Studio, so I’ll use it for this project.
đź’ˇ
|
A fantastic alternative to JDL Studio is the JHipster JDL Plugin for IntelliJ IDEA. Yuriy Artamonov created and maintains this plugin. It’s a great way to visualize your JDL and generate entities. |
Below is the entity diagram and JDL code needed to generate a simple blog with blogs, posts, and tags.
đź’ˇ
|
You can find a few other JDL samples on GitHub. |
If you’d like to follow along, copy/paste the contents of the JDL below into a blog.jdl
file.
entity Blog { name String required minlength(3) handle String required minlength(2) } entity Post { title String required content TextBlob required date Instant required } entity Tag { name String required minlength(2) } relationship ManyToOne { Blog{user(login)} to User with builtInEntity Post{blog(name)} to Blog } relationship ManyToMany { Post{tag(name)} to Tag{post} } paginate Post, Tag with infinite-scroll
Run the following command to import this file and generate entities, tests, and a UI.
jhipster jdl blog.jdl
You’ll be prompted to overwrite src/main/webapp/i18n/en/global.json
. Type a to overwrite this file, as well as others.
Restart the application with /.mvnw
.
You might notice that each entities' list screen is pre-loaded with data. faker.js creates this data. To turn it off, edit src/main/resources/config/application-dev.yml
, search for faker
and remove it from the liquibase.contexts
configuration. I made this change in this example’s code.
liquibase:
# Add 'faker' if you want the sample data to be loaded automatically
contexts: dev
đź’ˇ
|
If you still have data in your list screens after making this change, run ./mvnw clean to delete the H2 database.
|
Create a couple of blogs for the existing admin
and user
users and a few blog entries.
From these screenshots, you can see that users can see each other’s data and modify it.
đź’ˇ
|
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 BlogResource.java
and find the getAllBlogs()
method. Change the following line:
return blogRepository.findAll();
To:
return blogRepository.findByUserIsCurrentUser();
The findByUserIsCurrentUser()
method is generated by JHipster in the BlogRepository
class and allows limiting results by the current user. In BlogRepository
, add a where clause to the findAllWithToOneRelationships()
method to limit results by the current user.
public interface BlogRepository extends JpaRepository<Blog, Long> {
@Query("select blog from Blog blog where blog.user.login = ?#{authentication.name}")
List<Blog> findByUserIsCurrentUser();
// Find all eagerly and limit by current user
@Query("select blog from Blog blog left join fetch blog.user where blog.user.login = ?#{authentication.name}")
List<Blog> findAllWithToOneRelationships();
}
After making this change, re-compiling BlogRepository
should trigger a restart of the application thanks to Spring Boot’s Developer tools. If you navigate to http://localhost:8080/blog, you should only see the blog for the current user.
To add this same logic for entries, open PostResource.java
and find the getAllPosts()
method. Change the following line:
page = postRepository.findAll(pageable);
To:
page = postRepository.findByBlogUserLoginOrderByDateDesc(
SecurityUtils.getCurrentUserLogin().orElse(null), pageable);
Using your IDE, create this method in the PostRepository
class. It should look as follows:
Page<Post> findByBlogUserLoginOrderByDateDesc(String username, Pageable pageable);
While you’re in there, add a where clause to the findAllWithToOneRelationships()
method to limit results by the current user.
@Query(value = "select post from Post post left join fetch post.blog where post.blog.user.login = ?#{authentication.name}", countQuery = "select count(post) from Post post")
Page<Post> findAllWithToOneRelationships(Pageable pageable);
Recompile both changed classes and verify that the user
user only sees the posts you created for them.
Run npm run e2e
in a new terminal window to confirm everything works as expected.
You might notice that this application doesn’t look like a blog, and it doesn’t allow HTML in the content field.
When doing UI development on a JHipster-generated application, it’s nice to see your changes as soon as you save a file. JHipster uses Browsersync and webpack to power this feature. You enable this feature by running the following command in the blog
directory.
npm start
In this section, you’ll change the following:
-
Change the rendered content field to display HTML
-
Change the list of entries to look like a blog
If you enter HTML in the content
field of a blog post, you’ll notice it’s escaped on the list screen.
To change this behavior, open post.component.html
and change the following line:
<td>{{ post.content }}</td>
To:
<td [innerHTML]="post.content"></td>
After making this change, you’ll see that the HTML is no longer escaped.
To make the list of entries look like a blog, replace the @if (posts && posts.length)
block with the following code that uses a stacked layout in a single column.
@if (posts && posts.length) {
<div class="table-responsive table-entities" id="entities">
<div infinite-scroll
(scrolled)="loadPage(page + 1)"
[infiniteScrollDisabled]="page - 1 >= links['last']"
[infiniteScrollDistance]="0">
@for (post of posts; track trackId) {
<div data-cy="entityTable">
<a [routerLink]="['/post', post.id, 'view']" data-cy="entityDetailsButton">
<h2>{{ post.title }}</h2>
</a>
<small>Posted on {{ post.date | formatMediumDatetime }}
@if (post.blog) {
<span>in <a [routerLink]="['/blog', post.blog.id, 'view']">{{ post.blog.name }}</a></span>
}
</small>
<div [innerHTML]="post.content"></div>
<div class="btn-group mb-2 mt-1">
<button type="submit" [routerLink]="['/post', post.id, 'edit']" class="btn btn-primary btn-sm">
<fa-icon icon="pencil-alt"></fa-icon>
<span class="d-none d-md-inline" jhiTranslate="entity.action.edit" data-cy="entityEditButton">Edit</span>
</button>
<button type="submit" (click)="delete(post)" class="btn btn-danger btn-sm" data-cy="entityDeleteButton">
<fa-icon icon="times"></fa-icon>
<span class="d-none d-md-inline" jhiTranslate="entity.action.delete">Delete</span>
</button>
</div>
</div>
}
</div>
</div>
}
Now it looks more like a regular blog!
You can further enhance the security of your API by only allowing users that own a blog (or post) to edit it. Here’s some pseudocode to show the logic:
Optional<Blog> blog = blogRepository.findById(id);
if (<blog.user does not match current user>) {
throw new ResponseStatusException(HttpStatus.FORBIDDEN);
}
return ResponseUtil.wrapOrNotFound(blog);
Below is the patched BlogResource.java
with additional logic in each method to prevent data tampering.

You’ll need to make similar changes in PostResource.java
. See this commit for all the changes that you’ll need in these two classes, as well as their integration tests.
The changes you just made to limit data visibility will cause Cypress end-to-end tests to fail. To fix them, you need to change from selecting the last user to selecting the admin
user. Open blog.cy.ts
and change the blogSample
object to have a user assigned to it.
const blogSample = { name: 'lunch optimistically', handle: 'unrealistic', user: { id: 2, login: username }}
You’ll also need to update the should create an instance of Blog
test at the bottom. Right after the handle value assertion, select a user.
cy.get('[data-cy="user"]').select(username);
Then, change post.cy.ts
to update the test that creates a new post. This change adds a new blog that the post can relate to.

A JHipster application can be deployed anywhere a Spring Boot application can be deployed.
JHipster ships with support for deploying to Heroku, Kubernetes, AWS, and Azure. I’m using Heroku in this example because it doesn’t cost me anything to host it.
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 verify
The production profile is used to build an optimized JavaScript client. You can invoke this using webpack by running npm run webapp:build:prod
. The production profile also configures gzip compression with a servlet filter, cache headers, and monitoring via Micrometer. If you have a Graphite server configured in your application-prod.yml
file, your application will automatically send metrics data to it.
To deploy this application to Heroku, I logged in to my account using heroku login
from the command line. I already had the Heroku CLI installed.
$ heroku login

The source code for this project is available on GitHub at mraible/jhipster8-demo.
GitHub Actions is continually testing this project with configuration from its .github/workflows/main.yml
file. This file was generated using jhipster ci-cd
and everything passed on the first try! To make this work, I had to copy my Heroku API key from my account dashboard. Then, I added it in GitHub > Settings > Secrets and Variables > Actions > Repository secrets, naming it HEROKU_API_KEY
.
It’s a good idea to keep your dependencies up-to-date for security reasons. I recommend using Dependabot and adding a .github/dependabot.yml
file with the following YAML:
version: 2
updates:
- package-ecosystem: "github-actions"
directory: "/"
schedule:
interval: "weekly"
- package-ecosystem: "npm"
directory: "/"
schedule:
interval: "weekly"
- package-ecosystem: "maven"

I hope you’ve enjoyed learning how JHipster can help you develop modern web applications! It’s a nifty project, with an easy-to-use entity generator, a pretty UI, and many Spring Boot best-practice patterns. The project team follows six simple policies, paraphrased here:
-
The development team votes on policies.
-
JHipster uses technologies with their default configurations as much as possible.
-
Only add options when there is sufficient added value in the generated code.
-
Use strict versions for third-party libraries.
-
Provide similar user/developer experience across different options.
-
Developer experience can take precedence over other policies.
These policies help the project maintain its sharp edge and streamline its development process. 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!
Now that you’ve learned how to use Angular, Bootstrap, and Spring Boot with JHipster, go forth and develop great applications!
