1、建立並啟用模組

public class ZTasksModule extends AbstractModule{
    @Override
protected void configure() {
        bind(CompositeImageTask.class).asEagerSingleton();//繫結CompositeImageTask任務
    }

2、然後在application.conf中通過新增以下行來啟用該模組

play.modules.enabled += "tasks.ZTasksModule"

3、任務demo  CompositeImageTask.java

public class CompositeImageTask{
    private final ActorSystem actorSystem;
    private final ExecutionContext executionContext;
    @Inject
public CompositeImageTask(ActorSystem actorSystem, ExecutionContext executionContext) {
        this.actorSystem = actorSystem;
        this.executionContext = executionContext;
        this
 
.initialize();
    }
    private void initialize() {
        this.actorSystem.scheduler().schedule(
                Duration.create(1, TimeUnit.MINUTES), // initialDelay  專案啟動後該任務多長時間執行
Duration.create(10, TimeUnit.MINUTES), // interval     該任務執行週期
() ->composite(),
                this.executionContext
 
);
    }  

    //專案啟動後1分鐘執行該任務，然後每隔10分鐘執行一次

    public  void composite()  {

    /***任務邏輯***/

    }

}
