Activite+webSocket+spring实现消息推送(一对一聊天)

本文链接：https://blog.youkuaiyun.com/weixin_41572392/article/details/83545757

简介：

该功能我在程自己在学习时候尝试搭建的，可能会有很多问题，在这里只是做一下记录。直接上代码。如有不懂请联系楼主或者加群725395843 这里是技术讨论群。供大家讨论。

功能目的：

实现页面发送消息另一个页面收到消息。并且做数据及时存储等。

废话不说直接上代码：

前端jsp，注意：这里要引用stomp.min.js 在这里不做详细解释下载下来引入进行

<%@ 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">

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

<link rel="stylesheet" type="text/css" href="static/css/style.css" />

</head>
<body>

<div class="workingroom">
   <div class="loginDiv">
   <input id="message" type="text">
   <input type="button" class="thisButton" value="发送">
</div>
</body>

<script type="text/javascript" src="/SmallProgram/static/js/jquery-2.2.3.min.js"></script>
<script type="text/javascript" src="/SmallProgram/static/js/mask.js"></script>
<script type="text/javascript" src="/SmallProgram/static/js/stomp.min.js"></script>
<script type="text/javascript">
   $(".thisButton").click(function(){
       var url = "ws://127.0.0.1:61614/queue-test";

           var login = "admin";

           var passcode = "admin";

           //监听的队列

           //需要和发送者的发送的队列名称一致否则无法接受到数据

           destination = "queue-test";

           client = Stomp.client(url);

           var onconnect = function(frame) {

           client.subscribe(destination, function(message) {
           console.log(message.body);
           alert(message.body)
           alert("有新的订单,请及时处理")
           location.reload();
       });
       };
       client.connect(login, passcode, onconnect);
   })
</script>
<script type="text/javascript">
   $(".thisButton").click(function(){
       var message = $("#message").val();
       //发送消息
       $.ajax({
type: "POST",
url: "/SmallProgram/WxSmallProgramController/sendWebSocket",
data: {message,message},
success:function(Msg){
               alert(“发送成功”);
           }
});
   })
</script>
</html>

后台Controller (将不用的bao删调就可以)

package com.sinosoft.controller;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.jms.Destination;

import org.apache.activemq.command.ActiveMQQueue;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

/*

*/
@RestController
@RequestMapping("WxSmallProgramController")
public class WxSmallProgramController {
   private Logger logger = LoggerFactory.getLogger(this.getClass());
   @Autowired
   private UserDetailsService userDetailsService ;
   @Autowired
   UserService userService;
   @Autowired
   private ProducerService roducerService;

//测试链接
   @RequestMapping("webSocket")
   public ModelAndView webSocket(Integer user_id){
       ModelAndView model = new ModelAndView();
       model.setViewName("hello");
       return model;
   }


//发送消息

@RequestMapping("sendWebSocket")
   public Msg sendwebSocket(String message){
       Destination destination =new ActiveMQQueue("张佳鑫");
       roducerService.sendMessage(destination, message);
       Msg msg = new Msg();
       return msg;
   }



}

Service以及实现类

package com.sinosoft.service;

import javax.jms.Destination;

public interface ProducerService {
/**
* 向指定队列发送消息
*/
void sendMessage(Destination destination, final String msg);
/**
* 向默认队列发送消息
*/
void sendMessage(final String msg);
}

实现类：

package com.sinosoft.service.impl;

import javax.jms.Destination;
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.Service;

import com.sinosoft.service.ProducerService;

@Service
public class ProducerServiceImpl implements ProducerService {
@Autowired
private JmsTemplate jmsTemplate;

/**
* 向指定队列发送消息
*/
public void sendMessage(Destination destination, final String msg) {
System.out.println("向队列" + destination.toString() + "发送了消息------------" + msg);
jmsTemplate.send(destination, new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(msg);
}
});
}

/**
* 向默认队列发送消息
*/
public void sendMessage(final String msg) {
String destination = jmsTemplate.getDefaultDestination().toString();
System.out.println("向队列" +destination+ "发送了消息------------" + msg);
jmsTemplate.send(new MessageCreator() {
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage(msg);
}
});

}
}

配置文件:

spring.activemq.broker-url=tcp://127.0.0.1:61616
spring.activemq.in-memory=false
#true表示使用连接池
spring.activemq.pool.enabled=true
#连接池最大连接数
spring.activemq.pool.max-connections=5
#空闲的连接过期时间，默认为30秒
spring.activemq.pool.idle-timeout=30000
#强制的连接过期时间，与idleTimeout的区别在于：idleTimeout是在连接空闲一段时间失效，而expiryTimeout不管当前连接的情况，只要达到指定时间就失效。默认为0，never
spring.activemq.pool.expiry-timeout=0
