这是我之前在帖子中提出的另一个相关问题:Safely Terminating a Spring JMS application
我使用Spring启动的JMS应用程序正确处理所有内容并关闭而没有错误。为了实现这一点,我改变了一个bean:
@Bean
public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
factory.setConnectionFactory(mqConnectionFactory());
factory.setDestinationResolver(destinationResolver());
factory.setConcurrency("1");
factory.setErrorHandler(errorHandler());
factory.setSessionTransacted(true);
factory.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
return factory;
}
要:
@Bean
public DefaultMessageListenerContainer defaultMessageListenerContainer() {
DefaultMessageListenerContainer jmsListenerContainer = new DefaultMessageListenerContainer();
jmsListenerContainer.setConnectionFactory(mqConnectionFactory());
jmsListenerContainer.setDestinationResolver(destinationResolver());
jmsListenerContainer.setDestinationName(queueName);
jmsListenerContainer.setConcurrency("1");
jmsListenerContainer.setErrorHandler(errorHandler());
jmsListenerContainer.setSessionTransacted(true);
jmsListenerContainer.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
jmsListenerContainer.setAutoStartup(false);
return jmsListenerContainer;
}
问题在于,我本来可以创建一个"修补程序",因为我对spring的了解很少。当我偶然发现这篇文章时添加了已更改的bean jmsListenerContainer.setAutoStartup(false);
中的行:http://forum.spring.io/forum/spring-projects/integration/79176-illegalstateexception-no-message-listener-specified,因为没有autoStartup
设置为false我在日志中的每个已处理消息之后得到此消息:
java.lang.IllegalStateException: No message listener specified - see property 'messageListener'

at java.lang.Thread.run(Unknown Source) [?:1.8.0_74]
仍然可以正确处理和关闭所有内容,我只是在日志中看到这一点。不确定我的配置文件中是否存在冲突,这可能是其根源。我只是想确保这些更改不会导致问题,即使所有内容目前都按预期运行且没有错误。
最后这是我的整个配置类:
@Configuration
@EnableJms
public class MQConfig {
private static final Logger logger = LogManager.getLogger(MQConfig.class.getName());
@Value("${mq.hostName}")
String host;
@Value("${mq.port}")
Integer port;
@Value("${mq.queueManager}")
String queueManager;
@Value("${mq.queueName}")
String queueName;
@Value("${mq.channel}")
String channel;
@Autowired
Environment environment;
@Bean
public DefaultMessageListenerContainer defaultMessageListenerContainer() {
DefaultMessageListenerContainer jmsListenerContainer = new DefaultMessageListenerContainer();
jmsListenerContainer.setConnectionFactory(mqConnectionFactory());
jmsListenerContainer.setDestinationResolver(destinationResolver());
jmsListenerContainer.setDestinationName(queueName);
jmsListenerContainer.setConcurrency("1");
jmsListenerContainer.setErrorHandler(errorHandler());
jmsListenerContainer.setSessionTransacted(true);
jmsListenerContainer.setSessionAcknowledgeMode(Session.CLIENT_ACKNOWLEDGE);
jmsListenerContainer.setAutoStartup(false);
return jmsListenerContainer;
}
@Bean
public MQConnectionFactory mqConnectionFactory() {
MQConnectionFactory mqConnectionFactory = new MQConnectionFactory();
try {
mqConnectionFactory.setHostName(host);
mqConnectionFactory.setPort(port);
mqConnectionFactory.setQueueManager(queueManager);
mqConnectionFactory.setTransportType(1);
} catch (JMSException ex) {
logger.error(ex.getStackTrace());
}
return mqConnectionFactory;
}
@Bean
public DynamicDestinationResolver destinationResolver() {
DynamicDestinationResolver destinationResolver = new DynamicDestinationResolver();
try {
Connection connection = mqConnectionFactory().createConnection();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
destinationResolver.resolveDestinationName(session, queueName, false);
} catch (JMSException ex) {
logger.error(ex.getStackTrace());
}
return destinationResolver;
}
@Bean
public MQQueue mqQueue() {
MQQueue mqQueue = new MQQueue();
try {
mqQueue.setBaseQueueName(queueName);
mqQueue.setBaseQueueManagerName(queueManager);
} catch (JMSException ex) {
logger.error(ex.getStackTrace());
}
return mqQueue;
}
@Bean
public JmsErrorHandler errorHandler(){
return new JmsErrorHandler();
}
@Bean
public MQManager mqHoldManager(){
return new MQManager(host, port, queueName,
queueManager, channel);
}
@Bean
public MQInitializer mqInitializer(){
return new MQInitializer(environment);
}
}
思考?这太乱了吗?
编辑:JMS侦听器
@Component
public class MQConsumer {
@Resource(name = "mqHoldManager")
private MQManager mqHoldManager;
@Resource(name = "defaultMessageListenerContainer")
private DefaultMessageListenerContainer listenerContainer;
@Autowired
MQInitializer mqInitializer; /* To ensure this bean executes before Listener Setup not necessarily for any particular usage*/
final Logger logger = LogManager.getLogger(MQConsumer.class.getName());
private static ReportManager reportManager = new ReportManager();
private static boolean isFirstQueue = true;
@JmsListener(destination = "${mq.queueName}")
public void processOrder(String message) throws Exception {...}
答案 0 :(得分:1)
我很困惑。
DefaultJmsListenerContainerFactory
用于带注释的POJO方法:
@JmsListener(...)
public void foo(String bar) {...}
工厂用于为方法创建侦听器容器。
使用您的替换配置,我认为您没有在DefaultMessageListenerContainer
中配置消息监听器。
通常你会container.setMessageListner(myListener)
myListener
是MessageListener
,SessionAwareMessageListener
或MessageListenerAdapter
包裹POJO听众。
将autoStartup
设置为false并且从不启动容器除了将容器bean添加到上下文之外什么都不做。
我看不出你怎么能得到任何有关该配置的消息。
修改强>
您使用的是Spring Boot吗?如果是这样,它会为您创建一个默认的jmsListenerContainerFactory
- 这是我最好的猜测。
在这种情况下,您的停止代码并没有真正停止实际的容器 - 只是从未启动的“虚拟”容器。
我建议您@JmsListener
id
,@Autowire
JmsListenerEndpointRegistry
并致电registry.getListenerContainer("myListener").stop()
。
@JmsListener(id = "myListener", destination = "${mq.queueName}")
