使用spring + ActiveMQ 总结

Spring 整合JMS 基于ActiveMQ 实现消息的发送接收

看了网上很多文件,最后总结出了自己需要的。

一、下载并安装ActiveMQ

首先我们到apache官网上下载activeMQ(http://activemq.apache.org/download.html),进行解压后运行其bin目录下面的activemq.bat文件启动activeMQ。

二、Spring中加入ActiveMQ的配置

首先将相关的jar拷贝到项目的lib文件下

使用spring + ActiveMQ 总结

配置之前先看一下相关目录以便于理解

使用spring + ActiveMQ 总结

下面开始配置

<!-- ActiveMQ 连接工厂 -->
 <!-- 真正可以产生Connection的ConnectionFactory,由对应的 JMS服务厂商提供-->
 <bean id="connectinFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
  <!-- <property name="brokerURL" value="tcp://192.168.1.79:61616" /> -->
  <property name="brokerURL" value="${mqUrl}" />

  <property name="targetConnectionFactory" ref="connectinFactory"></property>
  <!-- Session缓存数量 -->
  <property name="sessionCacheSize" value="10"></property>
 </bean>

 <!-- 配置消息发送目的地方式 -->

下面展示一下Sender

public class Sender {
 private static ServletContext servletContext;
 private static WebApplicationContext ctx;

   QueueMessageProducer notifyMessageProducer = ((QueueMessageProducer) ctx.getBean("queueMessageProducer"));
   PhoneNoticeInfo noticeInfo = new PhoneNoticeInfo();

(下面先展示PhoneNoticeInfo 然后是 QueueMessageProducer
   noticeInfo.setNoticeContent("Hello Word");
   noticeInfo.setNoticeTitle("hello Word");
   noticeInfo.setReceiver("hello");
   noticeInfo.setReceiverPhone("1111111");
   notifyMessageProducer.sendQueue(noticeInfo);
  }

public static ServletContext getServletContext() {
  return servletContext;
 }
 public static void setServletContext(ServletContext servletContext) {
  Sender.servletContext = servletContext;
