Spring Jms异步消息推送

来源：互联网发布：淘宝十大动漫周边店编辑：程序博客网时间：2024/06/11 06:23

最近公司项目业务要求用户下单之后发送邮件通知功能，邮件发送功能我使用的是spring自带的mail功能见我的其他博客有讲解，但是邮件这段加入进去之后不能够影响原有的程序功能，比如：邮件发送失败导致系统报异常影响订单交易程序，因此，我在这里使用了异步消息推送服务，使用的技术：activeMQ+spring+jms，利用spring自带jms功能，实现了异步消息推送，这样即使邮件发送失败也不会影响主程序。好了，废话说多了，见代码。

//配置文件

<!-- started spring-jms config --><context:component-scan base-package="com.maimai.jms"/><!-- connection to amq --><amq:connectionFactory id="connectionFactory" brokerURL="tcp://localhost:61616"/><amq:queue id="queue" physicalName="spitter.queue"></amq:queue><bean id="jsmTemplate" class="org.springframework.jms.core.JmsTemplate"><property name="connectionFactory" ref="connectionFactory"></property></bean><jms:listener-container connection-factory="connectionFactory"><jms:listener destination="spitter.queue" ref="jmsreciever" method="getStr"/></jms:listener-container><bean id="jmsreciever" class="com.maimai.jms.RecieverJMS" /><!-- ended spring-jms config -->

//发送消息定义

package com.maimai.jms;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.Session;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.core.MessageCreator;import org.springframework.stereotype.Component;@Componentpublic class SenderJMS {@AutowiredJmsTemplate jmsTemplate;public void send(final String str){this.jmsTemplate.send("spitter.queue", new MessageCreator() {public Message createMessage(Session session) throws JMSException {// TODO Auto-generated method stubreturn session.createTextMessage(str);}});}}

//接收消息定义

package com.maimai.jms;import javax.jms.JMSException;import javax.jms.TextMessage;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jms.core.JmsTemplate;import org.springframework.stereotype.Component;@Componentpublic class RecieverJMS {@AutowiredJmsTemplate jmsTemplate;public void getStr(String str) throws JMSException{//TextMessage tm = (TextMessage) jmsTemplate.receive();//String str = tm.getText();System.out.println("==================================str="+str);}}

//程序调用jms，关键代码

public String Login() throws NoSuchAlgorithmException, UnsupportedEncodingException{this.jms.send("hello world !");String result = Constant.JSON_EMPTY;}

//打印结果
