jhipsterSampleMicroservice

This application was generated using JHipster 9.0.0-beta.3, you can find documentation and help at https://www.jhipster.tech/documentation-archive/v9.0.0-beta.3.

This is a "microservice" 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 [Consul]https://www.jhipster.tech/documentation-archive/v9.0.0-beta.3/consul/).

Project Structure

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

Development

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][].

Building for production

Packaging as jar

To build the final jar and optimize the jhipsterSampleMicroservice 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.

Packaging as war

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

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

Testing

Spring Boot tests

To launch your application's tests, run:

./mvnw verify

Gatling

Performance tests are run by Gatling and written in Scala. They're located in src/test/java/gatling/simulations.

You can execute all Gatling tests with

./mvnw gatling:test

Others

Code quality using Sonar

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][].

Docker Compose support

JHipster generates a number of Docker Compose configuration files in the src/main/docker/ folder to launch required third party services.

For example, to start required services in Docker containers, run:

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

To stop and remove the containers, run:

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

Spring Docker Compose Integration is enabled by default. It's possible to disable it in application.yml:

spring:
  ...
  docker:
    compose:
      enabled: false

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 an arm64 Docker image when using an arm64 processor OS, i.e., Apple Silicon chips (M*), running:

npm run java:docker:arm64

Then run:

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

For more information refer to 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.

Continuous Integration (optional)

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.
