集成事务
Spring提供的JMS的API中已经有了集成事务的功能,我们只要将上面监听容器的配置改成下面的就行了:
首先,将jmsTemplate设置成支持事务(它默认是不支持事务的):
<bean id="jmsTemplate"
class="org.springframework.jms.core.JmsTemplate">
<property name="connectionFactory">
<bean
class="org.springframework.jms.connection.SingleConnectionFactory">
<property name="targetConnectionFactory"
ref="jmsConnectionFactory" />
</bean>
</property>
<property name="sessionTransacted" value="true"/>
</bean>
然后再在消息监听容器中设置指定的事务管理:
<bean id="listenerContainer"
class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="jmsConnectionFactory" />
<property name="destination" ref="destination" />
<property name="messageListener" ref="resourceMessageListener" />
<!—jtaTransactionManager是系统中的事务管理类,在我们的系统中,是由Spring托管的 -->
<property name="transactionManager" ref="jtaTransactionManager" />
</bean>
这样配置之后,当事务发生回滚时,消息也会有回滚,即不发送出去。
4、其它高级应用
ActiveMQ还有许多其它高级的应用,如:自动重连机制,也就是保证当通信双方或多方的链接断裂后它会根据用户的设置自动连接,以保证建立可靠的传输;另外,ActiveMQ还有其它方式嵌入到Spring中,如它可以通过xbean, file等方式建立应用;它还可以通过JMX对消息的发送与接收进行实时查看;消息的确认方式等等,还有很多高级的应用,请参考
