Mybatis分布式事物

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： 
1、applicationContext.xml

7、把log4j.xml 也贴出来吧，兴许有的同学能用上

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”：

    <!-- 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>
