1、服务端

代码分为两部分：

一个是服务器终端类：用java注解来监听连接@ServerEndpoint、连接成功@OnOpen、连接失败@OnClose、收到消息等状态@OnMessage

import org.springframework.stereotype.Component;import javax.websocket.*;
import javax.websocket.server.ServerEndpoint;
import java.io.IOException;@Component
@ServerEndpoint("/websocket/fqa")
public class QwenWebSocket {@OnOpenpublic void onOpen(Session session){System.out.println("WebSocket opened: " + session.getId());}@OnMessagepublic void onMessage(String message, Session session){System.out.println("Message received: " + message);try{session.getBasicRemote().sendText("Echo: " + message);}catch (IOException e){e.printStackTrace();}}@OnClosepublic void onClose(Session session){System.out.println("WebSocket closed: " + session.getId());}@OnErrorpublic void onError(Throwable t){t.printStackTrace();}
}

一个是websocket的配置类，用于把spring中的ServerEndpointExporter对象注入进来

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.socket.server.standard.ServerEndpointExporter;@Configuration
public class WebSocketConfig {/*** 这个bean的注册,用于扫描带有@ServerEndpoint的注解成为websocket,如果你使用外置的tomcat就不需要该配置文件*/@Beanpublic ServerEndpointExporter serverEndpointExporter() {return new ServerEndpointExporter();}
}

2、客户端

普通的java工程即可，不需要是spring。

import javax.websocket.*;
import java.net.URI;@ClientEndpoint
public class MyWebSocketClient {@OnOpenpublic void onOpen(Session session){System.out.println("Connected to server");}@OnMessagepublic void onMessage(String message){System.out.println("Received message: " + message);}@OnClosepublic void onClose(CloseReason reason){System.out.println("Closing: " + reason.getReasonPhrase());}public static void main(String[] args) {try{WebSocketContainer container = ContainerProvider.getWebSocketContainer();URI uri = URI.create("ws://localhost:8080/websocket/fqa");Session session = container.connectToServer(MyWebSocketClient.class, uri);session.getBasicRemote().sendText("I'm client!");Thread.sleep(10000);}catch(Exception e){e.printStackTrace();}}
}
