第一步：添加Spring WebSocket的依赖jar包

<!-- 使用spring websocket依赖的jar包 -->
 <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-websocket</artifactId>
      <version>${spring-framework.version}</version>
  </dependency>
  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-messaging</artifactId>
      <version>${spring-framework.version}</version>
  </dependency>

第二步：建立一个类实现WebSocketConfigurer接口

package com.my.spring.context;

import com.my.business.spring.SpringWebSocketHandler;
import lombok.AllArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
import org.springframework.web.socket.handler.TextWebSocketHandler;
import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;

import java.util.HashMap;

/**
 * Spring Context - web socket配置
 * @author my Team
 * @version 2.0
 * @see com.my.business.spring.SpringWebSocketHandler
 */
@AllArgsConstructor(onConstructor = @__({
   @Autowired}))
@EnableWebMvc
@EnableWebSocket
public class SpringWebSocketConfig extends WebMvcConfigurationSupport implements WebSocketConfigurer {
   

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
   
		//HttpSessionHandshakeInterceptor拦截器，可以自定义，由于系统实现了session登录，这里就不需要再实现session与用户的绑定。
        registry.addHandler(webSocketHandler(), "/websocket").addInterceptors(new HttpSessionHandshakeInterceptor());
        registry.addHandler(webSocketHandler(), "/sockjs").addInterceptors(new <
