Lighty Google Guice Dependency Injection Extension

This project provides Lighty Core module for Google Guice Dependency Injection Extension. This extension is available for Lighty projects Application projects using Google Guice as DI.

io.lighty.core.controller.guice.LightyControllerModule

How to use it

1. Add dependency into your project

   <dependency>
      <groupId>io.lighty.core</groupId>
      <artifactId>lighty-controller-guice-di</artifactId>
   </dependency>

2. Use LightyControllerModule to initialize Guice Injector

  //1. initialize and start Lighty controller (MD-SAL, Controller, YangTools, Akka)
  LightyControllerBuilder lightyControllerBuilder = new LightyControllerBuilder();
  lightyController = lightyControllerBuilder
                .from(defaultSingleNodeConfiguration)
                .build();
  lightyController.start().get();

  //2. initialize Lighty Controller Module custom application beans
  LightyControllerModule lightyModule = new LightyControllerModule(lightyController.getServices());
  MyApplicationModule myApplicationModule = new MyApplicationModule();
  Injector injector = Guice.createInjector(lightyModule, myApplicationModule);
  ...

3. Inject & use ODL services in your code

import com.google.inject.Inject;
import com.google.inject.name.Named;

public class DataStoreServiceImpl implements DataStoreService {

    @Inject
    @Named("BindingDataBroker")
    private DataBroker bindingDataBroker;

    ...
}
