Jhipster : Create Spring Boot + Angular/React applications

In this tutorial, we are going to see about JHipster.

JHipster is a powerful development tool to generate, create and deploy spring boot and angular js or react js application faster. It will create an application for you in no time and it provides a lot of out of the box features such as logging, metrics, health etc.


I will demonstrate similar application which I have demonstrated for Spring MVC angular js example and you will realize how much easier it is to bootstrap Spring boot + angular/react.

Step 1: Quick installation

  1. Install Java 8 from the Oracle website.
  2. Install Node.js from the Node.js website (please use an LTS 64-bit version, non-LTS versions are not supported)
  3. Install Yarn from the Yarn website
  4. Open terminal
  5. If you want to use the JHipster Marketplace, install Yeoman: yarn global add yo
  6. Install JHipster with command: yarn global add generator-jhipster

Once you are done with the above installation, let’s create sample project.

Step 2: Project setup

  1. Open terminal and execute below commands
  2. mkdir  JhipsterHelloWorld
  3. cd JhipsterHelloWorld
  4. jhipster

This will ask you for lot of options to choose from.

? May JHipster anonymously report usage statistics to improve the tool over time? No
? Which *type* of application would you like to create? Monolithic application (recommended for simple projects)
? What is the base name of your application? JhipsterHelloWorld
? What is your default Java package name? org.arpit.java2blog
? Do you want to use the JHipster Registry to configure, monitor and scale your application? No
? Which *type* of authentication would you like to use? HTTP Session Authentication (stateful, default Spring Security mechanism)
? Which *type* of database would you like to use? SQL (H2, MySQL, MariaDB, PostgreSQL, Oracle, MSSQL)
? Which *production* database would you like to use? MySQL
? Which *development* database would you like to use? H2 with in-memory persistence
? Do you want to use the Spring cache abstraction? Yes, with the Ehcache implementation (local cache, for a single node)
? Do you want to use Hibernate 2nd level cache? No
? Would you like to use Maven or Gradle for building the backend? Maven
? Which other technologies would you like to use?
? Which *Framework* would you like to use for the client? Angular 6
? Would you like to enable *SASS* support using the LibSass stylesheet preprocessor? No
? Would you like to enable internationalization support? No
? Besides JUnit and Jest, which testing frameworks would you like to use?
? Would you like to install other generators from the JHipster Marketplace? No

Once you are done with above steps,it will build your project.

Step 3: Import project in IDE

We need to import the project in eclipse as maven project. Project will look like as below.

Jhipster project structure


  • Java code is contained in the src/main/java folder as always
  • The src/main/resources folder contains static resources used by java code. It also contains internationalization files and other configuration files.
  • You can find Unit and integration tests in the src/test/java folder


  • src/main/webapp is root folder for front hand.
  • The app folder contains AngularJS modules
  • i18n contains the internationalization files for the front end part
  • Unit tests for frontend are in the src/test/javascript/spec folder

As you can see, Jhipster has created a lot of packages and files for you to get started.

Step 4: Run npm

We need to start node.js server before we proceed. Run below commands in IDE.

cd JhipsterHelloWorld
npm start

Step 5: Create Entity called Country

Entities are building blocks of hipster application. Entities actually represent business objects such as User, Customer etc.

Creating an entity is actually quite easy.You just need to execute below commands and follow the instructions.

jhipster entity Country

Once you execute above command, you will get below options

Executing jhipster:entity Country
Options:The entity Country is being created.Generating field #1? 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? No================= Country =================
name (String)Generating field #2? Do you want to add a field to your entity? Yes
? What is the name of your field? population
? What is the type of your field? Long
? Do you want to add validation rules to your field? No================= Country =================
name (String)
population (Long)

Generating field #3

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

================= Country =================
name (String)
population (Long)

Generating relationships to other entities

? Do you want to add a relationship to another entity? No

================= Country =================
name (String)
population (Long)

? Do you want to use separate service class for your business logic? No, the REST controller should
use the repository directly
? Do you want pagination on your entity? No

Everything is configured, generating the entity…

Step 6: Build maven project

Build the maven project with "clean install" as goals.

Jhipster Maven build

Step 7: Run the project

go to src/main/java/org/arpit/java2blog and open JhipserHelloWorldApp.java

If you notice, this class is annotated with @SpringBootApplication, so when you will run this class, it will be executed as Spring boot application.
When you run above java class, you will get below output:

Step 8: Browse user interface

Go to "localhost:9000", you will see below screen.

Jhispter home screen

Click on Account -> "sign in" and login with
Username: admin
Password: admin

Jhispter sign in

Click on Entities-> Country

Jhispter home again

Then you will see below screen, click on "create new Country" button

Jhipster create new Country

Name: India
Population: 10000
and click on "save"

I have also added Nepal and china as Country.

Jhipster 3 countries

Click on Administration -> metrics, you will see below screen.

Jhipster metrics

Click on Administration -> health, you will see below screen.

Jhipster health

Click on Administration -> API, you will see below screen.

Jhispter API

Click on Administration -> Database and Connet to H2 database.
When we put query as "Select * from Country", you will be able to see 3 records in Country table.

Jhispter H2 database

As you can see, we did not write even any code, but still able to get lots of functionalities out of the box.Jhipster will definitely help you to bootstrap Spring boot and angular js application faster.

That’s all about Jhipster.
