        return new ServerEndpointExporter();

WebSocket.java

package com.yizhen.service;

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

    private Session session;

    private static CopyOnWriteArraySet<WebSocket> 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：

 <script  type="text/javascript">
        var websocket = null;
        if('WebSocket' in window) {
            websocket = new WebSocket('ws://bgyzuishuai.s1.natapp.cc/webSocket');
        }else {
            alert('该浏览器不支持订单提醒!');
        }

        websocket.onopen = function (event) {
            console.log('建立连接');
        }

        websocket.onclose = function (event) {
            console.log('连接关闭');
        }

        websocket.onmessage = function (event) {
            console.log('收到消息:' + event.data)
            //弹窗提醒, 播放音乐
            $('#dingdanxiaoxi').modal('show');

            document.getElementById('notice').play();
        }

        websocket.onerror = function () {
            alert('websocket通信发生错误！');
        }

        window.onbeforeunload = function () {
            websocket.close();
        }

    </script>

pom：

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>

最后@autowired   Websocket

使用websocket.sendMessage()发送消息
