替换GlobalSettings.onStart和onStop

Question

我正在尝试将我的GlobalSettings迁移到playframework 2.4,但我很难理解我应该做什么.

目前我的Global就像下面一样,我已经正确地将onRequest移出到RequestHandler:

public class Global extends GlobalSettings {

        private BackgroundTasks backgroundTasks;



        @Override
        public void onStart(Application arg0) {
            Logger.info("Starting background tasks");
            backgroundTasks = new BackgroundTasks();
        }

        @Override
        public void onStop(Application arg0) {
            Logger.info("Stopping background tasks");
            backgroundTasks.shutdown();
            super.onStop(arg0);

            Logger.info("Saving modules data");
            for(Module m: controllers.Application.modules){
                m.saveData();
            }
        }
    }

我认为它应该沿着(没有包装和进口)......

OnStartModule.java:

public class OnStartModule extends AbstractModule {
  @Override
  protected void configure() {    
    bind(BackgroundTasks.class).asEagerSingleton();
  }
}

BackgroundTasks.java:

@Singleton
public class BackgroundTasks {

  @Inject
  public BackgroundTasks(ApplicationLifecycle lifecycle) {
    lifecycle.addStopHook(() -> {
      Logger.info("Stopping background tasks");
      this.shutdown();

      Logger.info("Saving modules data");
      for(Module m: controllers.Application.modules){
        m.saveData();
      }
      return F.Promise.pure(null);
    });
  }
}

application.conf:

play.modules.enabled += "OnStartModule"
