activemq spring整合 以及虚拟主题设置

1. jmstemplate 配置

<bean id="jmstemplate" class="org.springframework.jms.core.JmsTemplate"><property name="connectionFactory" ref="mqConnectionFactory" /><property name="defaultDestination" ref="testqueue"/><property name="deliveryMode" value="1"></property> <property name="sessionTransacted" value="false"/> <!-- deliveryMode, priority, timeToLive 的开关，要生效，必须配置为true，默认false-->  <property name="explicitQosEnabled" value="false" /> <!-- 超时时间 --><property name="timeToLive" value="${acq.query.timeout}"/></bean>

 class="org.apache.activemq.command.ActiveMQQueue"><constructor-arg value="com.cn.testqueue" /></bean>

<bean id="mqConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory"><property name="connectionFactory"><bean class="org.apache.activemq.ActiveMQConnectionFactory"><property name="brokerURL" value="${mq.brokerURL}" /></bean></property></bean>

<p><em><span style="color:#2A00FF;">MQ_URL=failover:(tcp://ip:61616,tcp://ip:</span> <span style="color:#2A00FF;">61616)</span></em></p>

2.消息监听器配置

    <!-- 消息监听器 -->   <bean id="consumerMessageListener" class="com.activemq.lisenter.MessageListenterA"/>       <bean id="jmsContainer"        class="org.springframework.jms.listener.DefaultMessageListenerContainer">        <property name="connectionFactory" ref="mqConnectionFactory">        <property name="destination" ref="testqueue">        <property name="messageListener" ref="consumerMessageListener" />        <property name="sessionTransacted" value="true"></property>         <property name="concurrentConsumers" value="2"/>     </bean> 

3.引入 jar 包

<properties>  <activemq.version>5.9.1</activemq.version></properties><!-- activemq -->       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-broker</artifactId>           <version>${activemq.version}</version>       </dependency>       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-client</artifactId>           <version>${activemq.version}</version>       </dependency>       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-console</artifactId>           <version>${activemq.version}</version>       </dependency>       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-jaas</artifactId>           <version>${activemq.version}</version>       </dependency>       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-openwire-legacy</artifactId>           <version>${activemq.version}</version>       </dependency>       <dependency>           <groupId>org.apache.activemq</groupId>           <artifactId>activemq-spring</artifactId>           <version>${activemq.version}</version>       </dependency>

4. 消息发送

jmsTemplate.convertAndSend(Object message);

5. 消息异步接收

实现监听器MessageListener接口，配置成Spring Bean。只有一个方法需实现：public void onMessage(Message message);例如：public class <span style="font-family: Arial, Helvetica, sans-serif;">MessageListenterA </span><span style="font-family: Arial, Helvetica, sans-serif;">implements MessageListener {</span>@Overridepublic void onMessage(Message message) {if (!(message instanceof ObjectMessage)) {logger.info("接收的消息类型不匹配！");return;}try {ObjectMessage objectMessage = (ObjectMessage) message;ShortMessage smsMsg = (ShortMessage)objectMessage.getObject();//…………………} catch (JMSException e) {logger.error("jms异常", e);}}

注意：activemq  使用PooledConnectionFactory连接池引入 commons-pool2，如果weblogic版本较低 会与weblogic 的jar 包冲突，此时需要调整weblogic 加载顺序

在 web-inf 目录下面加入 weblogic.xml 

<?xml version="1.0" encoding="UTF-8"?><weblogic-web-app        xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xsi:schemaLocation="http://java.sun.com/xml/ns/javaeehttp://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsdhttp://xmlns.oracle.com/weblogic/weblogic-web-apphttp://xmlns.oracle.com/weblogic/weblogic-web-app/1.2/weblogic-web-app.xsd">    <container-descriptor>        <!--<prefer-web-inf-classes>true</prefer-web-inf-classes>-->        <prefer-application-packages>            <package-name>org.apache.commons.pool*</package-name>        </prefer-application-packages>    </container-descriptor></weblogic-web-app>

activemq虚拟主题  是为了解决同一个主题多个应用订阅，同一个应用集群的多台机器订阅只消费一次 ，主题订阅 注意 命名 是VirtualTopic开头，主题必须持久化，同一个应用clientId 相同

<!--主题订阅--><bean id="queue_market_topic" class="org.apache.activemq.command.ActiveMQTopic"><!--对列名称自定义，如果Activemq没有这个对列会新建--><constructor-arg value="VirtualTopic.TEST" /> </bean>

    <bean id="myListenerContainer"          class="org.springframework.jms.listener.DefaultMessageListenerContainer">          <property name="connectionFactory" ref="connectionFactory" />          <property name="pubSubDomain" value="true"/>          <property name="subscriptionDurable" value="true"/>          <property name="receiveTimeout" value="10000"/>          <property name="clientId" value="push_client_119" />          <property name="durableSubscriptionName" value="push_client_119"/>          <property name="destination" ref="myDestination" />          <property name="messageListener" ref="myTopicListenerA" />      </bean>
