스프링 통합 : 애플리케이션 컨텍스트 새로 고침시 예외 발생하기 2 회째

Question

다양한 게이트웨이와 서비스 활성기로 구성된 스프링 통합 프로젝트에서 애플리케이션 컨텍스트를 새로 고칩니다. 새로 고침은 처음에는 문제가 없지만 이후의 새로 고침 (이 간격을두고 완료)에서이 예외가 발생합니다.

컨트롤러 :

@RequestMapping(value = "/contextReload", method = RequestMethod.GET) 
public String contextReload() throws Exception { 
    LOG.info(" Reloading Application Context"); 
    refreshAsync(); 
    return "responseOK"; 
} 

private void refreshAsync() { 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      try { 
       Thread.sleep(REFRESH_WAIT_TIME_MILLIS); //This fixed the issue 
       getContextService().refresh(); 
      } catch (Exception e) { 
       LOG.error("Error in refreshing context: ", e); 
      } 
     } 
    }).start(); 
} 

ApplicationContextService

public synchronized void refresh(){ 
    /*Refresh from top to bottom such that child context beans 
    * have new parent bean reference*/ 
    while(!appContexts.isEmpty()){ 
     ConfigurableApplicationContext ctx = (ConfigurableApplicationContext)appContexts.pop(); 
     LOG.info("Refreshing context: "+ctx); 
     ctx.refresh(); 
     LOG.info("Finished refreshing context: "+ctx); 
    } 
    LOG.info("Context refresh complete!"); 
}

모든 포인터 왜 이런 일이 수에 관해서는?

Answer 1

모든 이전 싱글 톤의 파괴가 완료 될 때까지 기다려야합니다.

분리가 깨끗하지 않았습니다. 어느 bean이 파괴되지 않았는지 보려면 클래스 DefaultSingletonBeanRegistry의 로깅 출력을 늘리십시오.

또한

@Component 
    public class MyStopApp implements ApplicationListener<ContextClosedEvent> (... 
    @Autowired 
    DefaultSingletonBeanRegistry registry; 

    public void onApplicationEvent(final ContextClosedEvent event){ 
    registry.destroySingletons(); 
    }
