springBoot整合webSocket

1、使用注解@ServerEndpoint注解webSocket

@ServerEndpoint("/logWebSocket")public class LogWebSocketHandle {    /**     * 新的WebSocket请求开启     */    @OnOpen    public void onOpen(Session session) {    }    @OnMessage    public void onMessage(String message, Session session) {         logger.info("---------------->message："+message);    }    /**     * WebSocket请求关闭     */    @OnClose    public void onClose() {    }    @OnError    public void onError(Throwable thr) {        thr.printStackTrace();    }}

2、在页面创建webSocket链接

    var webSocketUrl = "ws://192.168.2.1:8080/webSocketPro/logWebSocket";    var websocket = new WebSocket(webSocketUrl);    websocket.onopen = function(e) {        //给服务器端发消息        websocket.send('message');    }    websocket.onmessage = function(event) {        // 接收服务端的消息         var data = event.data;    };

3、如果在tomcat下启动springBoot应用，请求webSocket访问404，需要在springBoot应用中注入webSocket配置，同时在webSocket实现类上添加@Component注解

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();       }  }

@ServerEndpoint("/logWebSocket")@Componentpublic class LogWebSocketHandle {}

4、springBoot中webSocket依赖的jar包

<dependency>    <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-starter-websocket</artifactId>    <version>1.4.1.RELEASE</version></dependency>
