Question

我的代码中有一个Spring JmsListener。它接收并使用了2天的消息，但是在这两天后突然没有收到来自外部activemq的消息。但是，它的队列中有一些待处理的消息。当我重置activemq和使用者时，使用者会收到大量消息。当消息挂起时，使用者连接到activemq（代表弹簧执行器日志）。日志和配置显示activemq没有将消息推送给使用者。我有另一个服务，例如此使用者，它从其他队列接收消息。第二消费者也有同样的问题。我想知道为什么会发生此问题，以及如何解决此问题。这是我的配置和日志：

消费者：

application.xml：

spring.jms.pub-sub-domain=false
spring.jms.template.delivery-mode=persistent
spring.activemq.broker-url=${BROKER_URL:failover:(tcp://activemq1:61616,tcp://activemq2:61616)?maxReconnectDelay=2500}
spring.activemq.user=${BROKER_USER:admin}
spring.activemq.password=${BROKER_PASSWORD:admin}

JmsConfiguration：

@EnableJms
@Configuration
public class JmsConfiguration {
    @Bean
    public JmsListenerContainerFactory<?> myFactory(ActiveMQConnectionFactory connectionFactory,
                                                    DefaultJmsListenerContainerFactoryConfigurer configurer) {
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();
        redeliveryPolicy.setMaximumRedeliveries(0);
        connectionFactory.setRedeliveryPolicy(redeliveryPolicy);
        factory.setMessageConverter(messageConverter());
        configurer.configure(factory, connectionFactory);
        return factory;
    }

    private MessageConverter messageConverter() {
        MappingJackson2MessageConverter messageConverter = new MappingJackson2MessageConverter();
        messageConverter.setTargetType(MessageType.TEXT);
        messageConverter.setTypeIdPropertyName("_type");
        return messageConverter;
    }
}

监听器：

@Component
public class MessageReceiver {


        @JmsListener(destination = Constant.OFFICE_REQUEST_QUEUE, containerFactory = "myFactory")
        public void receive(RequestMessage requestMessage,  @Headers Map<String,Object> headers) throws NonPersistenceServiceException {
            // do someting on received message
        }
    }

Activemq配置：

这种情况通常是以下两个问题之一的结果：

某些网络组件（路由器，防火墙）由于不活动而无提示地关闭了套接字，而没有通知客户端或服务器，因此，除非启用了心跳信号，否则连接已死。
使用者线程以某种方式“卡在”用户代码中，因此它停止接收新消息；进行堆栈转储以查看容器线程在做什么。

JmsListener不从Activemq接收消息
