1、**创建并启用模块**

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

2、**然后在application.conf中通过添加以下行来启用该模块**

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

3、**任务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 项目启动后该任务多长时间执行 Duration.create(10, TimeUnit.MINUTES), // interval 该任务执行周期 () ->composite(),
                    this.executionContext );
        }

//项目启动后1分钟执行该任务，然后每隔10分钟执行一次

public void composite()  {

/***任务逻辑***/

}
