dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-websocket/artifactId/dependency 2、增加websocket配置
package com.ruoyi.framework.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;/*** 开启WebSocket支持*/
Configuration
public class WebSocketConfig {Beanpublic ServerEndpointExporter serverEndpointExporter() {return new ServerEndpointExporter();}
}
3、增加websocket服务当然这部分后面还要修改
package com.ruoyi.framework.websocket;import cn.hutool.json.JSONUtil;
import com.ruoyi.common.core.domain.BaseProtocol;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;import javax.websocket.*;
import javax.websocket.server.PathParam;
import javax.websocket.server.ServerEndpoint;
import java.io.IOException;
import java.util.concurrent.CopyOnWriteArraySet;
import java.util.concurrent.atomic.AtomicInteger;// ServerEndpoint 声明并创建了webSocket端点, 并且指明了请求路径
// id 为客户端请求时携带的参数, 用于服务端区分客户端使用/*** ServerEndpoint 声明并创建了websocket端点, 并且指明了请求路径* uid 为客户端请求时携带的用户id, 用于区分发给哪个用户的消息* author nbacheng* date 2023-09-20
*/ServerEndpoint(/websocket/{uid})
Component
public class WebSocketServer {// 日志对象private static final Logger log LoggerFactory.getLogger(WebSocketServer.class);// 静态变量用来记录当前在线连接数。应该把它设计成线程安全的。//千万不要用private static AtomicInteger onlineCount new AtomicInteger(0);// concurrent包的线程安全Set用来存放每个客户端对应的MyWebSocket对象。private static CopyOnWriteArraySetWebSocketServer webSocketSet new CopyOnWriteArraySet();// private static ConcurrentHashMapString,WebSocketServer websocketList new ConcurrentHashMap();// 与某个客户端的连接会话需要通过它来给客户端发送数据private Session session;// 接收uidprivate String uid ;/** 客户端创建连接时触发* */OnOpenpublic void onOpen(Session session, PathParam(uid) String uid) {this.session session;webSocketSet.add(this); // 加入set中addOnlineCount(); // 在线数加1log.info(有新窗口开始监听: uid , 当前在线人数为 getOnlineCount());this.uid uid;try {sendMessage(连接成功);} catch (IOException e) {log.error(websocket IO异常);}}/*** 客户端连接关闭时触发**/OnClosepublic void onClose() {webSocketSet.remove(this); // 从set中删除subOnlineCount(); // 在线数减1log.info(有一连接关闭当前在线人数为 getOnlineCount());}/*** 接收到客户端消息时触发*/OnMessagepublic void onMessage(String message, Session session) {log.info(收到来自窗口 uid 的信息: message);// 群发消息for (WebSocketServer item : webSocketSet) {try {item.sendMessage(message);} catch (IOException e) {e.printStackTrace();}}}/*** 连接发生异常时候触发*/OnErrorpublic void onError(Session session, Throwable error) {log.error(发生错误);error.printStackTrace();}/*** 实现服务器主动推送(向浏览器发消息)*/public void sendMessage(String message) throws IOException {log.info(服务器消息推送message);this.session.getAsyncRemote().sendText(message);}/*** 发送消息到所有客户端* 指定uid则向指定客户端发消息* 不指定uid则向所有客户端发送消息* */public static void sendInfo(String message, PathParam(uid) String uid) throws IOException {log.info(推送消息到窗口 uid 推送内容: message);for (WebSocketServer item : webSocketSet) {try {// 这里可以设定只推送给这个sid的为null则全部推送if (uid null) {item.sendMessage(message);} else if (item.uid.equals(uid)) {item.sendMessage(message);}} catch (IOException e) {continue;}}}/*** * 给多个指定uid客户端发消息* * */public static void sendInfo(String message, PathParam(uids) String[] uids ) throws IOException {log.info(推送消息到窗口 uids 推送内容: message);for (String uid : uids) {sendInfo(message,uid);}}/*** 发送消息到所有客户端* 指定uid则向指定客户端发消息* 不指定uid则向所有客户端发送消息* */public static void sendInfo(BaseProtocol message, PathParam(uid) String uid) throws IOException {log.info(推送消息到窗口 uid 推送内容: message);for (WebSocketServer item : webSocketSet) {try {// 这里可以设定只推送给这个sid的为null则全部推送if (uid null) {item.sendMessage(JSONUtil.toJsonStr(message));} else if (item.uid.equals(uid)) {item.sendMessage(JSONUtil.toJsonStr(message));}} catch (IOException e) {continue;}}}public static synchronized int getOnlineCount() {return onlineCount.get();}public static synchronized void addOnlineCount() {WebSocketServer.onlineCount.incrementAndGet();}public static synchronized void subOnlineCount() {WebSocketServer.onlineCount.decrementAndGet();}public static CopyOnWriteArraySetWebSocketServer getWebSocketSet() {return webSocketSet;}}
4、在导航条里增加一个消息
el-tooltip content消息 effectdark placementbottom!--message idmessage classright-menu-item hover-effect / --header-notice idmessage classright-menu-item-message hover-effect //el-tooltip
界面就是
同时为了样式问题增加下面样式
right-menu-item-message {display: inline-block;padding: 0 8px;height: 100%;font-size: 18px;color: #5a5e66;vertical-align: text-bottom;width: 36px;.hover-effect {cursor: pointer;transition: background .3s;:hover {background: rgba(0, 0, 0, .025)}}}
5、增加HeaderNotice 组件当然现在是测试只作为websocket消息测试用后续正式还需要修改。

/scriptstyle langcss.header-notice-wrapper {top: 50px !important;}
/style
style langless scoped.header-notice {display: inline-block;transition: all 0.3s;span {vertical-align: initial;}}

6、增加websocket测试页面以便测试地址根据自己需要进行填写
templatedivel-input v-modelurl typetext stylewidth: 100% / nbsp; nbsp;br /el-button clickjoin typeprimary连接/el-buttonel-button clickexit typedanger断开/el-buttonbr /el-input typetextarea v-modelmessage :rows9 /el-button typeinfo clicksend发送消息/el-buttonbr /br /el-input typetextarea v-modeltext_content :rows9 / 返回内容br /br //div
/templatescript
export default {data() {return {url: ws://127.0.0.1:9060/websocket/ry,message: ,text_content: ,ws: null,};},methods: {join() {const wsuri this.url;this.ws new WebSocket(wsuri);const self this;this.ws.onopen function (event) {self.text_content self.text_content 已经打开连接! \n;};this.ws.onmessage function (event) {self.text_content event.data \n;};this.ws.onclose function (event) {self.text_content self.text_content 已经关闭连接! \n;};},exit() {if (this.ws) {this.ws.close();this.ws null;}},send() {if (this.ws) {const messageData {msgTxt: this.message,cmd: user}let strdata JSON.stringify(messageData);console.log(strdata,JSON.stringify(messageData));this.ws.send(strdata);//this.ws.send(this.message);} else {alert(未连接到服务器);}},},
};
/script
7、实际效果图
