sample-java-entity-decorators

Showing how to use @Entity, @Repository, @Controller and related Java annotations in Eclipse Dirigible.

Layout

sample-java-entity-decorators/   # Dirigible project (registry path)
└── demo/                          # Java package
    ├── Country.java               # @Entity — persisted via the data-store-java SessionFactory
    ├── CountryRepository.java     # @Repository extending JavaRepository<Country>
    └── CountryController.java     # @Controller exposing CRUD over /services/java/…

Usage

Drop this project into the Dirigible IDE (clone via the Git perspective and publish, or copy it to /registry/public/sample-java-entity-decorators/). The synchronizer compiles every .java file, registers @Entity classes with Hibernate, instantiates each @Repository, and binds the controller routes:

Method	URL
GET	/services/java/sample-java-entity-decorators/demo/CountryController
GET	/services/java/sample-java-entity-decorators/demo/CountryController/{id}
POST	/services/java/sample-java-entity-decorators/demo/CountryController
DELETE	/services/java/sample-java-entity-decorators/demo/CountryController/{id}

The OpenAPI fragment for the controller is published automatically at /services/openapi.

Dependency injection styles

• Field injection — CountryController uses @Inject CountryRepository (still supported).
• Constructor injection (preferred) — GreetingController receives a @Component GreetingService through its constructor; more testable.
• Programmatic lookup — Beans.get(...) for when an injection point isn't convenient.
