SpringMVC+MyBatis 相信已经是现在企业开发中常用技术了。
因为一些需求，我们需要集成JMS（我使用的是ActiveMQ），大家应该都知道，MQ也可以认为是一个数据源，数据也是数据源。这种情况下，如果我们在一个方法内操作JMS和数据库，我们就需要保证这个方法执行需要满足原子性。
这也就意味这一个问题，我们要多个数据源在同一个事务中。这里不枚举市面上的所有解决方案，其实atomikos JTA 是一个比较不错分布式事务管理器。
当然如果没有使用到JMS，在需要多数据源（也就是需要连接多个数据库）的情况同样适用。
下面将项目的主要配置贴出来共享：

对需要使用数据库数据源的方法使用 @Transactional 注解即可，在配置上，JMS的事务我们已经在配置文件中指定了。如下代码中指定的 transaction-manager=”jtaTransactionManager”：
|
1 2 3 4 5 6 7 8 9 10 |
<!-- 定义Queue监听器（有事务） --> <jms:listener-container destination-type="queue" container-type="default" connection-factory="amqConnectionFactory" transaction-manager="jtaTransactionManager" error-handler="jmsErrorHandler" acknowledge="transacted"> <jms:listener destination="xinge.queue.push.invokelog" ref="xgMessageReceiverInvokeLog" concurrency="5-100" /> </jms:listener-container> |
