Spirng Tomcat ActiveMQ JMS

基于Spring的JMS，ActiveMQ实现部署到Tomcat，下面是详细的代码，不解释。

 

applicationContext-jms.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<!-- 创建连接工厂 -->
	<bean id="jmsConnectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean">
		<property name="jndiName" value="java:comp/env/jms/ConnectionFactory" />
	</bean>

	<!-- 声明消息目标 -->
	<bean id="destination" class="org.springframework.jndi.JndiObjectFactoryBean">
		<property name="jndiName" value="java:comp/env/jms/Queue" />
	</bean>

	<!-- 创建JMS模板 -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
		<property name="connectionFactory" ref="jmsConnectionFactory" />
		<property name="defaultDestination" ref="destination" />
	</bean>

	<!-- 消息发布者 -->
	<bean id="sender" class="message.Sender">
		<property name="jmsTemplate" ref="jmsTemplate" />
	</bean>

	<!-- 消息订阅者 -->
	<bean id="receive" class="message.Receiver" />

	<!-- listener container，MDP无需实现接口 -->
	<bean id="listenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="jmsConnectionFactory" />
		<property name="destination" ref="destination" />
		<property name="messageListener" ref="receive" />
	</bean>
</beans>

 

使用到了jndi

webapp/META-INF/context.xml

<Context antiJARLocking="true">
	<Resource name="jms/ConnectionFactory"
		auth="Container"
		type="org.apache.activemq.ActiveMQConnectionFactory"
		description="JMS Connection Factory"
		factory="org.apache.activemq.jndi.JNDIReferenceFactory"
		brokerURL="vm://localhost"
		brokerName="LocalActiveMQBroker" />
	<Resource name="jms/Queue"
		auth="Container"
		type="org.apache.activemq.command.ActiveMQQueue"
		description="JMS Queue"
		factory="org.apache.activemq.jndi.JNDIReferenceFactory"
		physicalName="FOO.BAR" />
</Context>
