큐가 다운되었을 때 Spring RabbitTemplate.execute가 응답하지 않는다

Question

RabbitMQ 채널의 상태를 확인하기 위해 서버 속성을 가져 오려고합니다. 내가 의도적으로 토끼 MQ를 중지하고이 방법을 실행할 때

rabbitTemplate.execute(new ChannelCallback<String>() { 
       @Override 
       public String doInRabbit(Channel channel) throws Exception { 
        Map<String, Object> serverProperties = channel.getConnection() 
          .getServerProperties(); 
        return serverProperties.get("version").toString(); 
       } 
      }); 

그러나, 그것은 시간 초과로 영원히 대신 응답 : 여기 내 코드입니다.

RabbitMQ의 생동감을 표명하는 방법이 있습니까? &?

스레드 덤프 복용 스레드의 상태는 다음

TIMED_WAITING

인 스레드 덤프이다.

그 상태에있을 때 스레드 덤프를 가져갈 수 있습니까? Connection Refused 예외가 발생합니다 ...

@SpringBootApplication 
public class So46776458Application { 

    public static void main(String[] args) { 
     SpringApplication.run(So46776458Application.class, args); 
    } 

    @Bean 
    public ApplicationRunner runner(RabbitTemplate rabbitTemplate) { 
     return args -> { 
      System.out.println(rabbitTemplate.execute(new ChannelCallback<String>() { 

       @Override 
       public String doInRabbit(Channel channel) throws Exception { 
        Map<String, Object> serverProperties = channel.getConnection().getServerProperties(); 
        return serverProperties.get("version").toString(); 
       } 

      })); 
     }; 
    } 

}
