SpringMVC Websoket 测试网页即时通讯

本文主要是介绍SpringMVC Websoket 测试网页即时通讯，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

说明：测试项目是 springmvc + maven 框架

项目框架图

1.使用的jar包

<dependency><groupId>javax</groupId><artifactId>javaee-api</artifactId><version>7.0</version><scope>provided</scope>
</dependency>

2.后端controller层代码

AdminController 用户登录类代码

/**  * 用户controller  *  * @author HUYONG  * @create 2016-12-08  */ @Controller @RequestMapping("/admin") public class AdminController extends BaseController { private static Logger LOGGER = LoggerFactory.getLogger(AdminController.class);   @Autowired  AndysosoService andysosoService;   /**  * 用户登录  * @param userName  * @param password  * @return  */  @RequestMapping(value = "/adminLogin") @ResponseBody  public Result adminLogin(HttpServletRequest request, String userName, String password){ Map<String,Object> map = Maps.newHashMap();  AndysosoAdminDO adminDO = null;  int status = 0;  try { if(StringUtils.isNotEmpty(userName) && StringUtils.isNotEmpty(password)){ adminDO = andysosoService.getAndysosoAdminDO(userName,password);  } if(null != adminDO){ request.getSession().setAttribute("andysosoAdmin",adminDO);  status = 1;  } }catch (Exception e){ LOGGER.error("用户登录出现异常！",e);  } map.put("status",status);  return successResponse(map);  } }

AndysosoController 进入user_im.jsp 页面的类代码

/*** 功能点controller** @author HUYONG* @create 2016-12-08*/
@Controller
@RequestMapping("/andysoso")
public class AndysosoController extends BaseController{private static Logger LOGGER = LoggerFactory.getLogger(AndysosoController.class);@AutowiredAndysosoService andysosoService;/*** 进入IM页面* @return*/@RequestMapping(value = "/actionImView")public ModelAndView actionImView(HttpServletRequest request){Map<String,Object> map = Maps.newHashMap();String viewUrl = "";try {AndysosoAdminDO adminDO = (AndysosoAdminDO)request.getSession().getAttribute("andysosoAdmin");if(null != adminDO){List<AndysosoAdminDO> adminList = andysosoService.getAndysosoAdminDOList();map.put("andyAdmin",adminDO);map.put("adminList",adminList);viewUrl = "admin/user_im";}}catch (Exception e){LOGGER.error("进入IM页面出现异常！",e);}return createMav(viewUrl,map);}
}

WebsocketControllrt 类代码

package com.weijuju.iag.andysoso.personal.controller.websocket;import net.sf.json.JSONObject;
import org.apache.commons.lang.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;import javax.websocket.*;
import javax.websocket.server.PathParam;
import javax.websocket.server.ServerEndpoint;
import java.io.IOException;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;/*** WebSocket处理类** @author HUYONG* @create 2016-12-06*/
@ServerEndpoint("/websocket.ws/{userCode}")
public class WebsocketControllrt {private static Logger LOGGER = LoggerFactory.getLogger(WebsocketControllrt.class);private static Map<String,Session> webSocketSet = new ConcurrentHashMap<>();/*** 打开连接事触发* @param session*/@OnOpenpublic void onOpen(@PathParam("userCode") String userCode,Session session){LOGGER.info("打开websocket连接...");webSocketSet.put(userCode,session);}/*** 收到客户端消息时触发，并发送给特定用户* @param textJson* @return*/@OnMessagepublic String onMessage(String textJson){String userCode = "";String message = "";try {if(StringUtils.isNotEmpty(textJson)){//解析字符串JSONObject object = JSONObject.fromObject(textJson);userCode = object.getString("sendName");message = object.getString("message");Session session = webSocketSet.get(userCode);if(null != session){session.getBasicRemote().sendText(message);}}} catch (IOException e) {e.printStackTrace();} finally {}return "已经给"+userCode+"发送消息啦！message："+message;}/*** 异常时触发*/@OnErrorpublic void onError(Throwable throwable) {LOGGER.info("Websocket连接出现异常:");LOGGER.info(throwable.getMessage(), throwable);}/*** 关闭连接时触发*/@OnClosepublic void onClose(@PathParam("userCode") String userCode) {LOGGER.info("Websocket 关闭连接...");webSocketSet.remove(userCode);}
}

3.前端JSP页面代码

index.jsp 登录页代码 如下：

<%@ page language="java"  pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<h2>Login Websoket IM View</h2>
<p>请输入用户名：<input id="userName" type="text"/></p>
<p>请输入密码：<input id="password" type="password"/></p>
<button onclick="login()">登录</button>
<hr/>
</body>
<script src="resource/jquery-2.2.4.js"></script>
<script type="text/javascript">function login(){var userName = $("#userName").val();var password = $("#password").val();$.ajax({type:"post",url:"/admin/adminLogin",data:{userName:userName,password:password},dataType:"json",success:function(data){if(data.model.status == 1){window.location.href = "/andysoso/actionImView";}else{alert("登录失败！");}}});}
</script>
</html>

user_im.jsp  代码 如下：

<%@ page language="java"  pageEncoding="utf-8"%>
<%@include file="/common/taglibs.jsp" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<body>
<h2>Hello World! Action Websoket  <span>当前登录用户：${andyAdmin.userName}</span></h2>
<div style="width: 100%;"><div style="float: left; width: 70%; height: 100%; background-color: antiquewhite;"><p id="message"></p></div><div id="friend" style="float: right; width: 30%; height: 100%; background-color: aquamarine;"><p>好友列表</p><c:forEach items="${adminList}" var="admin"><p><a href="#" onclick="createReceiveUser(${admin.userName})">${admin.userName}</a></p></c:forEach></div>
</div>
<hr/>
<p>给<span id="sendName">${andyAdmin.userName}</span>发送消息：<input id="text" type="text"/>&nbsp;<button onclick="send()">发送消息</button></p>
<button onclick="closeWebSocket()">关闭WebSocket连接</button>
</body>
<script src="/resource/jquery-2.2.4.js"></script>
<script type="text/javascript">var userName = "${andyAdmin.userName}";var websocket = null;//判断当前浏览器是否支持WebSocketif ('WebSocket' in window) {//取到一个客户端的socketwebsocket = new WebSocket("ws://127.0.0.1:8080/websocket.ws/"+userName);}else {alert('当前浏览器 Not support websocket')}//连接发生错误的回调方法websocket.onerror = function () {setMessageInnerHTML("WebSocket连接发生错误");};//连接成功建立的回调方法websocket.onopen = function () {setMessageInnerHTML("<span style='color:red;'>WebSocket连接成功</span>");}//接收到消息的回调方法websocket.onmessage = function (event) {setMessageInnerHTML(event.data);}//连接关闭的回调方法websocket.onclose = function () {setMessageInnerHTML("WebSocket连接关闭");}//监听窗口关闭事件，当窗口关闭时，主动去关闭websocket连接，防止连接还没断开就关闭窗口，server端会抛异常。window.onbeforeunload = function () {closeWebSocket();}//将消息显示在网页上function setMessageInnerHTML(innerHTML) {document.getElementById('message').innerHTML += innerHTML + '<br/>';}//关闭WebSocket连接function closeWebSocket() {websocket.close();}//发送消息function send() {var message = document.getElementById('text').value;var sendName = $("#sendName").text();var textJson = '{"sendName":"'+sendName+'","message":"'+message+'"}'if(websocket.readyState != 3){websocket.send(textJson);}else{alert("websocket连接已经关闭或者出现网络异常！");}}//指定消息接收人function createReceiveUser(userName){alert("给"+userName+"发送消息");$("#sendName").text(userName);}
</script>
</html>
