我有一个使用Spring连接到TIBCO(队列)的独立应用程序。有时,由于各种原因,服务器会关闭TIBCO连接。大多数事情正在从中恢复。但是,有时由于以下错误,JmsTemplate无法发送响应。我已经重试,但是相同的错误不断出现(请参见下面的跟踪)。
可能很重要的细节:
我正在使用DefaultMessageListenerContainer来获取请求并在该接收线程中发送响应。另外,我对DefaultMessageListenerContainer和JmsTemplate使用相同的连接工厂。

使用Spring框架与TIBCO队列进行通信。这是配置。 DefaultMessageListenerContainer接收到一条消息,进行处理,并使用JmsTemplate发送回响应。接收方和发送方之间共享连接工厂(这可能是个问题吗?)。
<bean id="connectionFactory"
class="org.springframework.jms.connection.SingleConnectionFactory">
<constructor-arg ref="tibcoJNDI" />
<property name="targetConnectionFactory">
<bean class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiTemplate" ref="tibcoJNDI"/>
<property name="jndiName" value="${tibco.queueConnectionFactory}" />
</bean>

还有一个细节可能会有所帮助。我只是注意到第一个例外实际上是不同的。首先存在“连接已关闭”异常,然后是多个“会话已关闭”异常(重试)。

最佳答案
看来Spring无法正确处理这种情况。我通过重写JmsTemplate(下面的代码)并自己处理异常(清理会话和连接)解决了此问题。我希望这有帮助。
public <T> T execute(SessionCallback<T> action, boolean startConnection) throws JmsException {
try {
return super.execute(action, startConnection);
} catch (JmsException jmse) {
logger.error("Exception while executing in JmsTemplate (will cleanup session & connection): ", jmse);
Object resourceHolder =
TransactionSynchronizationManager.getResource(getConnectionFactory());
if (resourceHolder != null && resourceHolder instanceof JmsResourceHolder) {
((JmsResourceHolder)resourceHolder).closeAll();
}
throw jmse;
}
}
