springBoot2.0+vue实现websocket通信【最新，亲测有效】

先来看下效果，如果是你想要的效果就继续往下面看

如果你只是单纯的想使用前端或者后端也是可以的

前端：vue

后端：java

1、WebSocketConfig

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;

@Configuration
public class WebSocketConfig {

   @Bean
   public ServerEndpointExporter serverEndpointExporter() {
      return new ServerEndpointExporter();
   }
}

2、WebSocket

package com.xdx97.party.common.config;

import org.springframework.stereotype.Component;

import javax.websocket.OnClose;
import javax.websocket.OnMessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.PathParam;
import javax.websocket.server.ServerEndpoint;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.CopyOnWriteArraySet;

@Component
@ServerEndpoint("/websocket/{shopId}")
//此注解相当于设置访问URL
public class WebSocket {

    private Session session;

    private static CopyOnWriteArraySet webSockets =new CopyOnWriteArraySet<>();
    private static Map sessionPool = new HashMap();

    @OnOpen
    public void onOpen(Session session, @PathParam(value="shopId")String shopId) {
        this.session = session;
        webSockets.add(this);
        sessionPool.put(shopId, session);
        System.out.println("【websocket消息】有新的连接，总数为:"+webSockets.size());
    }

    @OnClose
    public void onClose() {
        webSockets.remove(this);
        System.out.println("【websocket消息】连接断开，总数为:"+webSockets.size());
    }

    @OnMessage
    public void onMessage(String message) {
        System.out.println("【websocket消息】收到客户端消息:"+message);
    }

    // 此为广播消息
    public void sendAllMessage(String message) {
        for(WebSocket webSocket : webSockets) {
            System.out.println("【websocket消息】广播消息:"+message);
            try {
                webSocket.session.getAsyncRemote().sendText(message);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    // 此为单点消息 (发送文本)
    public void sendTextMessage(String shopId, String message) {
        Session session = sessionPool.get(shopId);
        if (session != null) {
            try {
                session.getBasicRemote().sendText(message);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

    // 此为单点消息 (发送对象)
    public void sendObjMessage(String shopId, Object message) {
        Session session = sessionPool.get(shopId);
        if (session != null) {
            try {
                session.getAsyncRemote().sendObject(message);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

}

3、测试

你后台写一个请求的方法，把下面代码放进去就好了

for (int i = 0; i < 10; i++){
    Thread.sleep(1000);
    webSocket.sendTextMessage(shipId, ""+i);
}

并且注入webSocket

@Autowired
private WebSocket webSocket;

给你看看我的方法做参考

鉴于有几个小伙伴需要源码，我又重新写了这个demo，获取方式关注公众号后台回复：WebSocketDemo
