我的代码中有一个Spring JmsListener。它接收和消费消息2天，但在这2天后突然收到来自外部activemq的消息。但是队列中有一些待处理的消息。当我重置activemq和consumer时，消费者会收到大量消息。消息等待消费者连接到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。我有另一个像这个消费者的服务，从其他队列接收消息。第二个消费者也有同样的问题。我想知道为什么会出现这个问题，我该如何解决这个问题。这是我的配置和日志：
消费者：
application.xml中：
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：
activemq.xml中：
