java - Spring-ActiveMQ : DefaultMessageListenerContainer not getting destroyed

Question

我使用 Spring JMS DefaultMessageListenerContainer 并在 Spring 的 init 方法上初始化队列，并在 destroy 方法上销毁 listnereContainer 。 但是，当我使用“./catalina.sh stop”命令关闭 tomcat 服务器时，在使用线程转储工具时出现以下异常:

"localhost-startStop-2" #155 daemon prio=5 os_prio=0 tid=0x00007fd4c0015800 nid=0x5265 in Object.wait() [0x00007fd4c4f60000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) - waiting on <0x00000007752ccae8> (a java.lang.Object) at java.lang.Object.wait(Object.java:502) at org.springframework.jms.listener.DefaultMessageListenerContainer.doShutdown(DefaultMessageListenerContainer.java:545) - locked <0x00000007752ccae8> (a java.lang.Object) at org.springframework.jms.listener.AbstractJmsListeningContainer.shutdown(AbstractJmsListeningContainer.java:237) at org.springframework.jms.listener.AbstractJmsListeningContainer.destroy(AbstractJmsListeningContainer.java:177) at com.bng.ocg.queue.QueueConnection.destroy(QueueConnection.java:71) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

以下是 init 和 destroy 方法:

public void init() {
    try {
        connection = pooledConnectionFactory.createConnection();
        session = connection.createSession(false,
                Session.DUPS_OK_ACKNOWLEDGE);

        updateDefaultQueue();
        updateDefaultConsumer();
    } catch (JMSException e) {
        Logger.sysLog(LogValues.error, this.getClass().getName(), coreException.GetStack(e));
    } catch (Exception e) {
        Logger.sysLog(LogValues.error, this.getClass().getName(), coreException.GetStack(e));
    }
}

public void destroy(){
    for(DefaultMessageListenerContainer defaultMessageListenerContainer : defaultMessageListenerContainersCdrQueue)
        defaultMessageListenerContainer.destroy();

    for(DefaultMessageListenerContainer defaultMessageListenerContainer : defaultMessageListenerContainersDataSyncMsgQueue)
        defaultMessageListenerContainer.destroy();

    for(DefaultMessageListenerContainer defaultMessageListenerContainer : defaultMessageListenerContainersUrlHitterMsgQueue)
        defaultMessageListenerContainer.destroy();
    try {
        session.close();
    } catch (JMSException e) {
        Logger.sysLog(LogValues.error, this.getClass().getName(), coreException.GetStack(e));
    }
    try {
        connection.close();
    } catch (JMSException e) {
        Logger.sysLog(LogValues.error, this.getClass().getName(), coreException.GetStack(e));
    }
    pooledConnectionFactory.clear();
}

private void updateDefaultQueue() {
    for (int i = 0; i < cdrQueueInitialLength; i++) {
        cdrQueueList.add(cdrQueueNamePrefixString + i);
    }

    for (int i = 0; i < dataSyncMsgQueueInitialLength; i++) {
        dataSyncMsgQueueList.add(dataSyncMsgQueueNamePrefixString + i);
    }

    for (int i = 0; i < urlHitterMsgQueueInitialLength; i++) {
        urlHitterMsgQueueList.add(urlHitterMsgQueueNamePrefixString + i);
    }
}

private void updateDefaultConsumer() throws JMSException 
{
    /*for (int i = 0; i < cdrQueueInitialLength; i++) {
        defaultMessageListenerContainer = defaultMessageListenerContainerFactory
                .getObject();
        defaultMessageListenerContainer.setDestination(session
                .createQueue(cdrQueueList.get(i)));
        defaultMessageListenerContainer
                .setMessageListener(cdrMessageListener);
        defaultMessageListenerContainer.start();
        defaultMessageListenerContainersCdrQueue
                .add(defaultMessageListenerContainer);
    }*/

    for (int i = 0; i < dataSyncMsgQueueInitialLength; i++) {
        defaultMessageListenerContainer = defaultMessageListenerContainerDataSyncFactory
                .getObject();
        defaultMessageListenerContainer.setDestination(session
                .createQueue(dataSyncMsgQueueList.get(i)));
        defaultMessageListenerContainer
                .setMessageListener(dataSyncMsgListener);
        defaultMessageListenerContainer.start();
        defaultMessageListenerContainersDataSyncMsgQueue
                .add(defaultMessageListenerContainer);
    }

    for (int i = 0; i < urlHitterMsgQueueInitialLength; i++) {
        defaultMessageListenerContainer = defaultMessageListenerContainerUrlHitterFactory
                .getObject();
        defaultMessageListenerContainer.setDestination(session
                .createQueue(urlHitterMsgQueueList.get(i)));
        defaultMessageListenerContainer
                .setMessageListener(urlHitterMsgListener);
        defaultMessageListenerContainer.start();
        defaultMessageListenerContainersUrlHitterMsgQueue
                .add(defaultMessageListenerContainer);
    }
}

有什么建议可以解决这个问题吗？

我认为你的destroy()没有被调用??

您必须将@PreDestroy添加到您的destroy()方法中或使用spring @EventListener或实现ApplicationListener

@EventListener({ ContextClosedEvent.class })
public void destroy() {

}


@Component
public class ContextClosed implements ApplicationListener<ContextClosedEvent> {

    @Override
    public void onApplicationEvent(final ContextClosedEvent event) {
       destroy(); // your destroy
    }
}
