Question

我愿开始在散射服务器开端上台的单邮局。因此,我有附加说明的“Async annotation”方法。

我有一个班子,负责应用生计接口。当我从这个类别中讲我的同化方法时,它从来就永远不会一帆风顺地开始,并打破目前的read。当我把我的同仁方法从春季控制师班上说出来时,它从来就永远不会破灭并开始。

Why async method executed successfully from one class and not from the other class?

我做了什么错误,我如何在服务器启动时采用我的同化方法?

提前感谢。

<><>Edit>: 我尝试采用“Bean”接口,“PostConstruct, init-method”方法,称我为同yn,但从未执行过。我后来认识到,我的缺席是真的,因此,我把zy变成假,让我的开业。现在,它执行我的棘手方法,但是它打破了目前的线索,现在又是一个问题,我面临的是,我的服务器确实是 stop的,但我不得不有力地阻止我的服务器。

Answer 1

首先无需执行<代码>ApplicationListener接口。你正在与春天合作——应用环境足够。

Second you are talking about Spring @Async, it means that your task should be started from Application Context and Controller bean is a part of it.

你们需要确保你在春季Xml档案中拥有<条码>和>;通知驱动的和>;。

您可以开始履行“伙伴关系”职能:

@Component
public class SampleBeanImpl implements SampleBean {

  @Async
  void doSomething() { … }
}


@Component
public class SampleBeanInititalizer {

  @Autowired
  private final SampleBean bean;

  @PostConstruct
  public void initialize() {
    bean.doSomething();
  }
}

Answer 2

基于春季的参引 ,@Async在申请启动期间有限制:

@Async can not be used in conjunction with lifecycle callbacks such as @PostConstruct. To asynchronously initialize Spring beans you currently have to use a separate initializing Spring bean that invokes the @Async annotated method on the target then.

So, in your case, maybe it d be good to have an InitializingBean implementation with your target bean and then start the daemon through that.

您是否在申请中添加了<代码><annotation-led> 标签? http://static.childrensource.org/children/docs/3.1.1.RELEASE/children-framework-vis/html/scheduling.html#scheduling-annotation-support-namespace” rel=“nofollow” Spring reference doc:

为使“斜线”和“Async说明”都能够把任务名称空间的提示因素列入你的配置。

注:您还应考虑召集一次executor例会。 http://www.childrenframework.org/schema/task/children-task-3.1.xsd”rel=“nofollow”>task schema definition:

界定一个ThreadPoolTaskExecutor 案,具有可图形的集合规模、格恩-能力、保持平衡和拒绝政策价值。 See Javadoc for the org.childrenframework.scheduling.annotation.EnableAsync annotation for information oncode-based Options to this XML elements.

因此,要建立一个由五条read子支撑的检察官:

<task:annotation-driven executor="myExecutor"/>
<task:executor id="myExecutor" pool-size="5"/>

Answer 4

my english is pool. you must set the Service Class @Lazy(false).

Answer 5

@asyn 是春季框架的一部分, 你们的听众们的用词吗? 否则,我就建议开始采用你作为同仁的方法。

Answer 6

I use @PostConstruct with a thread executor

@PostConstruct
public void startServer() {
    final var executorService = Executors.newSingleThreadExecutor();
    executorService.submit(()-> {
      try {

        // make a call to a service that will not stop on it s own
        grpcServer.start().awaitTermination();

      } catch (InterruptedException e) {
        Thread.currentThread().interrupt();
      } catch (IOException e) {
        throw new UncheckedIOException(e);
      }
    });
}

这些工作有:。你们如何使用“JMX”的跳板,只使用一个非网络的跳板。
