使用Open MQ时的Spring JMS会话问题

Question

我正在使用spring-jms-3.0.6.RELEASE和open MQ。关于为什么会提出以下例外情况，你有什么想法吗？

2012-05-02 17:56:18,420 [stuJmsContainer-803059] WARN
org.springframework.jms.listener.DefaultMessageListenerContainer - Setup of JMS message listener invoker failed for destination 

'TestQ' - trying to recover. Cause:

Answer 1

根据ConnectionAdapter源代码和OpenMQ邮件列表上的这个归档线程，Spring或您的代码本身在单个JMS连接上创建了多个会话。

可以通过将系统属性imq.jmsra.inACC设置为false来禁用此OpenMQ行为（引发错误），但这并不令人满意。

没有事务管理器，Spring使用org.springframework.jms.connection.SingleConnectionFactory为多个消费者共享单个连接。

您应该将DefaultMessageListenerContainer cacheLevelName属性设置为CACHE_NONE，以便每个消费者线程在单个连接上获得自己的会话。
