This application was generated using JHipster 8.2.1, you can find documentation and help at https://www.jhipster.tech/documentation-archive/v8.2.1.

This is a "gateway" application intended to be part of a microservice architecture, please refer to the Doing microservices with JHipster page of the documentation for more information.

This application is configured for Service Discovery and Configuration with Consul. On launch, it will refuse to start if it is not able to connect to Consul at http://localhost:8500. For more information, read our documentation on Service Discovery and Configuration with Consul.

Node is required for generation and recommended for development. package.json is always generated for a better development experience with prettier, commit hooks, scripts and so on.

In the project root, JHipster generates configuration files for tools like git, prettier, eslint, husky, and others that are well known and you can find references in the web.

/src/* structure follows default Java structure.

• .yo-rc.json - Yeoman configuration file JHipster configuration is stored in this file at generator-jhipster key. You may find generator-jhipster-* for specific blueprints configuration.
• .yo-resolve (optional) - Yeoman conflict resolver Allows to use a specific action when conflicts are found skipping prompts for files that matches a pattern. Each line should match [pattern] [action] with pattern been a Minimatch pattern and action been one of skip (default if omitted) or force. Lines starting with # are considered comments and are ignored.
• .jhipster/*.json - JHipster entity configuration files
• /src/main/docker - Docker configurations for the application and services that the application depends on

To start your application in the dev profile, run:

./mvnw

For further instructions on how to develop with JHipster, have a look at Using JHipster in development.

Congratulations! You've selected an excellent way to secure your JHipster application. If you're not sure what OAuth and OpenID Connect (OIDC) are, please see What the Heck is OAuth?

To log in to your app, you'll need to have Keycloak up and running. The JHipster Team has created a Docker container for you that has the default users and roles. Start Keycloak using the following command.

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

The security settings in src/main/resources/config/application.yml are configured for this image.

spring:
  ...
  security:
    oauth2:
      client:
        provider:
          oidc:
            issuer-uri: http://localhost:9080/realms/jhipster
        registration:
          oidc:
            client-id: web_app
            client-secret: web_app
            scope: openid,profile,email

Some of Keycloak configuration is now done in build time and the other part before running the app, here is the list of all build and configuration options.

Before moving to production, please make sure to follow this guide for better security and performance.

Also, you should never use start-dev nor KC_DB=dev-file in production.

When using Kubernetes, importing should be done using init-containers (with a volume when using db=dev-file).

If you'd like to use Okta instead of Keycloak, it's pretty quick using the Okta CLI. After you've installed it, run:

okta register

Then, in your JHipster app's directory, run okta apps create and select JHipster. This will set up an Okta app for you, create ROLE_ADMIN and ROLE_USER groups, create a .okta.env file with your Okta settings, and configure a groups claim in your ID token.

Run source .okta.env and start your app with Maven or Gradle. You should be able to sign in with the credentials you registered with.

If you're on Windows, you should install WSL so the source command will work.

If you'd like to configure things manually through the Okta developer console, see the instructions below.

First, you'll need to create a free developer account at https://developer.okta.com/signup/. After doing so, you'll get your own Okta domain, that has a name like https://dev-123456.okta.com.

Modify src/main/resources/config/application.yml to use your Okta settings.

spring:
  ...
  security:
    oauth2:
      client:
        provider:
          oidc:
            issuer-uri: https://{yourOktaDomain}/oauth2/default
        registration:
          oidc:
            client-id: {clientId}
            client-secret: {clientSecret}
security:

Create an OIDC App in Okta to get a {clientId} and {clientSecret}. To do this, log in to your Okta Developer account and navigate to Applications > Add Application. Click Web and click the Next button. Give the app a name you’ll remember, specify http://localhost:8080 as a Base URI, and http://localhost:8080/login/oauth2/code/oidc as a Login Redirect URI. Click Done, then Edit and add http://localhost:8080 as a Logout redirect URI. Copy and paste the client ID and secret into your application.yml file.

Create a ROLE_ADMIN and ROLE_USER group and add users into them. Modify e2e tests to use this account when running integration tests. You'll need to change credentials in src/test/javascript/e2e/account/account.spec.ts and src/test/javascript/e2e/admin/administration.spec.ts.

Navigate to API > Authorization Servers, click the Authorization Servers tab and edit the default one. Click the Claims tab and Add Claim. Name it "groups", and include it in the ID Token. Set the value type to "Groups" and set the filter to be a Regex of .*.

After making these changes, you should be good to go! If you have any issues, please post them to Stack Overflow. Make sure to tag your question with "jhipster" and "okta".

If you'd like to use Auth0 instead of Keycloak, follow the configuration steps below:

• Create a free developer account at https://auth0.com/signup. After successful sign-up, your account will be associated with a unique domain like dev-xxx.us.auth0.com
• Create a new application of type Regular Web Applications. Switch to the Settings tab, and configure your application settings like:
  • Allowed Callback URLs: http://localhost:8080/login/oauth2/code/oidc
  • Allowed Logout URLs: http://localhost:8080/
• Navigate to User Management > Roles and create new roles named ROLE_ADMIN, and ROLE_USER.
• Navigate to User Management > Users and create a new user account. Click on the Role tab to assign roles to the newly created user account.
• Navigate to Auth Pipeline > Rules and create a new Rule. Choose Empty rule template. Provide a meaningful name like JHipster claims and replace Script content with the following and Save.

function (user, context, callback) {
  user.preferred_username = user.email;
  const roles = (context.authorization || {}).roles;

  function prepareCustomClaimKey(claim) {
    return `https://www.jhipster.tech/${claim}`;
  }

  const rolesClaim = prepareCustomClaimKey('roles');

  if (context.idToken) {
    context.idToken[rolesClaim] = roles;
  }

  if (context.accessToken) {
    context.accessToken[rolesClaim] = roles;
  }

  callback(null, user, context);
}

• In your JHipster application, modify src/main/resources/config/application.yml to use your Auth0 application settings:

spring:
  ...
  security:
    oauth2:
      client:
        provider:
          oidc:
            # make sure to include the ending slash!
            issuer-uri: https://{your-auth0-domain}/
        registration:
          oidc:
            client-id: {clientId}
            client-secret: {clientSecret}
            scope: openid,profile,email
jhipster:
  ...
  security:
    oauth2:
      audience:
        - https://{your-auth0-domain}/api/v2/

To build the final jar and optimize the gateway application for production, run:

./mvnw -Pprod clean verify

To ensure everything worked, run:

java -jar target/*.jar

Refer to Using JHipster in production for more details.

To package your application as a war in order to deploy it to an application server, run:

./mvnw -Pprod,war clean verify

JHipster Control Center can help you manage and control your application(s). You can start a local control center server (accessible on http://localhost:7419) with:

docker compose -f src/main/docker/jhipster-control-center.yml up

To launch your application's tests, run:

./mvnw verify

Sonar is used to analyse code quality. You can start a local Sonar server (accessible on http://localhost:9001) with:

docker compose -f src/main/docker/sonar.yml up -d

Note: we have turned off forced authentication redirect for UI in src/main/docker/sonar.yml for out of the box experience while trying out SonarQube, for real use cases turn it back on.

You can run a Sonar analysis with using the sonar-scanner or by using the maven plugin.

Then, run a Sonar analysis:

./mvnw -Pprod clean verify sonar:sonar -Dsonar.login=admin -Dsonar.password=admin

If you need to re-run the Sonar phase, please be sure to specify at least the initialize phase since Sonar properties are loaded from the sonar-project.properties file.

./mvnw initialize sonar:sonar -Dsonar.login=admin -Dsonar.password=admin

Additionally, Instead of passing sonar.password and sonar.login as CLI arguments, these parameters can be configured from sonar-project.properties as shown below:

sonar.login=admin
sonar.password=admin

For more information, refer to the Code quality page.

You can use Docker to improve your JHipster development experience. A number of docker-compose configuration are available in the src/main/docker folder to launch required third party services.

For example, to start a postgresql database in a docker container, run:

docker compose -f src/main/docker/postgresql.yml up -d

To stop it and remove the container, run:

docker compose -f src/main/docker/postgresql.yml down

You can also fully dockerize your application and all the services that it depends on. To achieve this, first build a docker image of your app by running:

npm run java:docker

Or build a arm64 docker image when using an arm64 processor os like MacOS with M1 processor family running:

npm run java:docker:arm64

Then run:

docker compose -f src/main/docker/app.yml up -d

When running Docker Desktop on MacOS Big Sur or later, consider enabling experimental Use the new Virtualization framework for better processing performance (disk access performance is worse).

For more information refer to Using Docker and Docker-Compose, this page also contains information on the docker-compose sub-generator (jhipster docker-compose), which is able to generate docker configurations for one or several JHipster applications.

To configure CI for your project, run the ci-cd sub-generator (jhipster ci-cd), this will let you generate configuration files for a number of Continuous Integration systems. Consult the Setting up Continuous Integration page for more information.
