我正在做一个spring-integration + rabbitMQ应用程序。我从一个主类调用一个网关发送给rabbitmq我的消息,它完美的工作,但由于一些奇怪的原因,我的主要方法继续运行,起初我想我可能在我的春天背景中留下了一个轮询器,但那'事实并非如此。 这里是我的代码:为什么我的主要方法继续运行?

public final class Main { 

    private static final Logger LOGGER = Logger.getLogger(Main.class); 

    @Autowired 
    static 
    ChatGateway chatGateway; 

    private Main() { } 

    /** 
    * Load the Spring Integration Application Context 
    * 
    * @param args - command line arguments 
    */ 
    public static void main(String args[]) { 
     Mensaje mensaje = new Mensaje(); 
     mensaje.setClienteID("clienteXXX"); 

     ClassPathXmlApplicationContext ctx = new 
     ClassPathXmlApplicationContext("classpath:META-INF/spring/integration/spring-integration-context.xml"); 
     chatGateway = (ChatGateway) ctx.getBean("chatGateway"); 

     chatGateway.enviarAlarma(mensaje); 

    } 
} 

,这里是我的Spring上下文:

为什么我的主要方法继续运行即使它发送的消息? 在此先感谢。

它会继续前进,因为它没有被告知结束。

你可以使用:

System.exit(0);

return;

main(String[] args)

+0

末这似乎做的工作。我认为一个主要的方法不会完成,除非它有一个无限循环。 – linker85

实际上,问题在于RabbitMQ客户端运行非守护线程当您准备关闭应用程序时,可以使用'ctx.destroy()',它将在连接工厂调用'destroy()',关闭连接并停止连接的线程。 –
