java实现基于activeMQ的消息推送

此文章是基于　　搭建Jquery+SpringMVC+Spring+Hibernate+MySQL平台

 一. jar包介绍

　　1. 点击此下载 apache-activemq-5.3.0，得到：

activemq-all-5.3.0.jar
activemq-web-5.3.0.jar

　　2. spring-framework-4.3.4.RELEASE 的 libs 文件夹下得到：

spring-jms-4.3.4.RELEASE.jar

二. 相关程序代码

　　1. applicationInterface.xml

    </bean>        
    
    <!-- 消息发送端 -->
    <bean id="jmsSender"

    <bean id="msgListener"

</beans>

　　2. JmsSender.java，消息发送器接口

package com.ims.interfaces.jms.activeMQ;

public interface JmsSender {
    public void send(final MsgContext context);
}

　　3. JmsSenderImpl.java，消息发送器实现

package com.ims.interfaces.jms.activeMQ;

import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.ObjectMessage;
import javax.jms.Session;

import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

public class JmsSenderImpl implements JmsSender{
    private JmsTemplate jmsTemplate;
    
    /**
     * 消息通告队列，表示点到点通讯模型
     */
    private Destination msgQueue;    
    
    /**
     * 发送消息
     * @param context 消息上下文
     */
    public void send(final MsgContext context) {
        getJmsTemplate().send(getMsgQueue(), new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                final ObjectMessage message = session.createObjectMessage();
                message.setObject(context);
                return message;
            }
        });
    }
    
    public JmsTemplate getJmsTemplate() {
        return jmsTemplate;
    }
    public void setJmsTemplate(JmsTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }
    
    
    public Destination getMsgQueue() {
        return msgQueue;
    }
    public void setMsgQueue(Destination msgQueue) {
        this.msgQueue = msgQueue;
    }
        
}

　　4. MsgContext.java，消息上下文类

package com.ims.interfaces.jms.activeMQ;

import java.io.Serializable;
import java.util.Collection;

public class MsgContext implements Serializable{
    
    private static final long serialVersionUID = -7877770277875813295L;

    /**
     * 消息接收者
     */
    private final Collection<String> users;         
    
    /**
     * 发送的消息
     */
    private final String message; 
    
    /**
     * 发送的方式
     */
    private final Collection<String> modes;         
    
    public MsgContext(Collection<String> users, String message, 
            Collection<String> modes){
        this.users = users;
        this.message = message;
        this.modes = modes;
    }

    public Collection<String> getUsers() {
        return users;
    }

    public String getMessage() {
        return message;
    }

    public Collection<String> getModes() {
        return modes;
    }
}

　　5. MsgListener.java，消息监听、执行器

package com.ims.interfaces.jms.activeMQ;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;

import org.springframework.jms.support.JmsUtils;

public class MsgListener implements MessageListener{

    /**
     * 监听到有消息时，执行的操作
     * @param msg 消息对象
     */
    @Override
    public void onMessage(Message message) {
        if(message == null) { return; }    
        // 获取对象消息
        final ObjectMessage objectMessage = (ObjectMessage) message;    
        
        // 消息上下文
        MsgContext context = null;        
        
        try {
            // 从对象消息中获取消息上下文对象
            context = (MsgContext) objectMessage.getObject();
        }catch (JMSException e) {
            JmsUtils.convertJmsAccessException(e);
            return;
        }
        
        System.out.println(context.getMessage());
        if(context==null || context.getModes()==null || context.getModes().size()==0){
            return;
        }
        
        // 取到消息上下文后，可执行自定义操作
    }

}

　　6. TestController.java，测试jms消息发送

package com.ims.web.controller;

import java.util.Collection;
import java.util.HashSet;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import com.ims.common.ServiceLocator;
import com.ims.interfaces.jms.activeMQ.JmsSender;
import com.ims.interfaces.jms.activeMQ.MsgContext;

@Controller
@RequestMapping("test")
public class TestController extends BaseController{
    
    @RequestMapping("view")
    public ModelAndView test(){
        ModelAndView view = new ModelAndView("test.jsp");
        return view;
    }
    
    @RequestMapping("jms!send")
    public void send(@RequestParam String msg){
        JmsSender jmsSender = ServiceLocator.getService("jmsSender");
        Collection<String> users = new HashSet<String>();
        Collection<String> modes = new HashSet<String>();
        MsgContext msgContext = new MsgContext(users, msg, modes);
        jmsSender.send(msgContext);
    }
}

　　7. jms.jsp，测试jms消息发送

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN">
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
 <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>测试</title>
    <%@ include file="/common/basePath.jsp"%>
 </head>
 <body>
 ~~~~~~~~~~~~~~~~~~~~~~jms消息发送~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 <br><br>  
   消息: <input type="text" name="msg" id="msg"> 
 <br><br>
 <button type="button" onclick="send();">发送</button>
 
 <script type="text/javascript" src="content/js/jquery/jquery-1.8.1.min.js"></script>
 <script type="text/javascript">
     function send(){
         $.ajax({
             url:rootPath+"/test/jms!send.do?msg="+$('#msg').val(),
             async:false
         });            
     }
 </script>
 </body>
</html>

三. 测试

　　1. 访问：http://localhost:8080/ims/test/jms.do

　　2. 输入消息内容，点击发送，MsgListener 类会在后台输出消息内容
