Question

在SimpleMessageListenerContainer调用后，消费者未在shutdownTimeout AnnotationConfigApplicationContext.close()内完成执行时，我的Spring应用程序将挂起。

监听器：

public class LongRunningMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        System.out.println("Got " + new String(message.getBody()));
        try {
            Thread.sleep(5000L);
        } catch (InterruptedException e) {
            System.out.println("Interrupted");
            Thread.currentThread().interrupt();
        }
        System.out.println("Finished execution");
    }
}

配置：

@Configuration
public class Config {

    @Bean
    public MessageListenerContainer messageListenerContainer() {
        SimpleMessageListenerContainer messageListenerContainer = new SimpleMessageListenerContainer(connectionFactory());
        messageListenerContainer.setQueueNames("myqueue");
        messageListenerContainer.setMessageListener(new LongRunningMessageListener());
        messageListenerContainer.setShutdownTimeout(1000);
        return messageListenerContainer;
    }

    @Bean
    public ConnectionFactory connectionFactory() {
        return new CachingConnectionFactory("localhost");
    }
}

主：

public static void main(String[] args) throws InterruptedException {
    AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(Config.class);
    Thread.sleep(1000L);
    applicationContext.close();
}

如果我增加shutdownTimeout，一切都很好，但是超时行为看起来像个错误。

关于你对这个问题的评论（回应@ Artem的解决方法）...

我也试过这个解决方案。它适用于这个简单的情况（Thread.sleep（）），但是当监听器正在做的时候不起作用＆＃34;真正的＆＃34;例如，长期等待IO的工作。

如果用户代码处于不间断状态（如等待套接字I / O），框架无法执行任何操作。你需要以某种方式关闭套接字。

使用RabbitMQ的spring-amqp没有正常关闭
