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”:
<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>
