WebSocket.java

package com.yizhen.service;

import javax.websocket.OnClose;
import javax.websocket.OnMessage;

@Component
@ServerEndpoint("/webSocket")
@Slf4j
public class WebSocket {

    private Session session;

    private static CopyOnWriteArraySet webSocketSet = new CopyOnWriteArraySet<>();

    @OnOpen
    public void onOpen(Session session) {
        this.session = session;
        webSocketSet.add(this);
        log.info("【websocket消息】有新的连接, 总数:{}", webSocketSet.size());
    }

    @OnClose
    public void onClose() {
        webSocketSet.remove(this);
        log.info("【websocket消息】连接断开, 总数:{}", webSocketSet.size());
    }

    @OnMessage
    public void onMessage(String message) {
        log.info("【websocket消息】收到客户端发来的消息:{}", message);
    }

    public void sendMessage(String message) {
        for (WebSocket webSocket: webSocketSet) {
            log.info("【websocket消息】广播消息, message={}", message);
            try {
                webSocket.session.getBasicRemote().sendText(message);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

}

需要消息提示的界面：

pom：

	org.springframework.boot
	spring-boot-starter-websocket

最后@autowired   Websocket

使用websocket.sendMessage()发送消息
