接收消息后的處理類 GameHandler :

import java.net.URI;
import org.springframework.web.socket.BinaryMessage;
import org.springframework.web.socket.CloseStatus;
import org.springframework.web.socket.PongMessage;
import org.springframework.web.socket.TextMessage;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.AbstractWebSocketHandler;

public class GameHandler extends AbstractWebSocketHandler {
 /**
  * 處理字符串類的信息
  *
  * @param session
  * @param message
  * @throws Exception
  */
 @Override
 protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
  session.sendMessage(new TextMessage(message.asBytes()));
 }

 /**
  * 處理二進制類的信息
  *
  * @param session
  * @param message
  * @throws Exception
  */
 @Override
 protected void handleBinaryMessage(WebSocketSession session, BinaryMessage message) throws Exception {
  session.sendMessage(new BinaryMessage(message.getPayload()));
 }

 /**
  * ping-pong
  *
  * @param session
  * @param message
  * @throws Exception
  */
 @Override
 protected void handlePongMessage(WebSocketSession session, PongMessage message) throws Exception {
	
 }
 /**
  * 傳出錯誤的處理
  *
  * @param session
  * @param exception
  * @throws Exception
  */
 @Override
 public void handleTransportError(WebSocketSession session, Throwable exception) throws Exception {
 }
 /**
  * 連接關閉的處理
  *
  * @param session
  * @param status
  * @throws Exception
  */
 @Override
 public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
 }
 /**
  * 連接建立后的處理
  *
  * @param session
  * @throws Exception
  */
 @Override
 public void afterConnectionEstablished(WebSocketSession session) throws Exception {	
 }
}

 握手信息攔截器 WebSocketHandshakeInterceptor :

import java.util.Map;
import javax.servlet.http.Cookie;
import org.springframework.http.server.ServerHttpRequest;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.http.server.ServletServerHttpRequest;
import org.springframework.web.socket.WebSocketHandler;
import org.springframework.web.socket.server.HandshakeInterceptor;

public class WebSocketHandshakeInterceptor implements HandshakeInterceptor {
 @Override
 public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse shr1, WebSocketHandler wsh, Map<String, Object> attributes) throws Exception {
  // 此處可以做一些權限認證的事情或者其他
  return true;
 }
 @Override
 public void afterHandshake(ServerHttpRequest shr, ServerHttpResponse shr1, WebSocketHandler wsh, Exception excptn) {	
 }
}

使用WebSocket的配置類 WebSocketConfig :

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;

@Configuration
@EnableWebSocket
public class WebSocketConfig extends WebMvcConfigurerAdapter implements WebSocketConfigurer {
@Override
 public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
  // 允許連接的域,只能以http或https開頭
  String[] allowsOrigins = {"http://127.0.0.1:1213", "http://localhost:1213"};
  registry.addHandler(gameHandler(),"/game").addInterceptors(handshakeInterceptor()).setAllowedOrigins(allowsOrigins);
 }
 @Bean
 public GameHandler gameHandler() {
  return new GameHandler();
 }
 @Bean
 public WebSocketHandshakeInterceptor handshakeInterceptor() {
  return new WebSocketHandshakeInterceptor();
 }
}

啟動類 Launcher :

@SpringBootApplication
public class Launcher {
 public static void main(String[] params) {
  SpringApplication.run(Launcher.class, params);
	}
}

配置文件 main/resources/application.properties:

server.port=1213
server.session-timeout=1800
server.undertow.io-threads=4
server.undertow.worker-threads=20
server.undertow.buffer-size=1024
server.undertow.buffers-per-region=1024
server.undertow.direct-buffers=true

      $(function () {
       $('[data-toggle="popover"]').popover();
      });
      return false;
     }
//關閉WebSocket連接
     function closeWebSocket() {
      if (websocket) {
       websocket.close();
      }
      return false;
     }

//將消息顯示在網頁上
     function setMessageInnerHTML(who, msg) {
      var message = null;

      } else {

到此就可以使用 WebSocket 進行前后端的通信了，如果大家還有不明白的或者有更好的方法，可以在下方的留言區討論。
