在Spring Boot中使用WebSocket实现服务端和Java客户端的实时通信，可以分为几个步骤来完成。这里将详细介绍服务端和Java客户端的具体实现。
服务端设置
添加依赖： 在pom.xml文件中添加Spring WebSocket的依赖。

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

配置WebSocket处理器： 创建一个配置类来注册WebSocket的Endpoint。

   import org.springframework.context.annotation.Configuration;
   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.WebSocketHandler;
   import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;

   @Configuration
   @EnableWebSocket
   public class WebSocketConfig implements WebSocketConfigurer {

       private final WebSocketHandler webSocketHandler;

       public WebSocketConfig(WebSocketHandler webSocketHandler) {
           this.webSocketHandler = webSocketHandler;
       }

       @Override
       public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
           registry.addHandler(webSocketHandler, "/ws/chat")
                   .addInterceptors(new HttpSessionHandshakeInterceptor())
                   .setAllowedOrigins("*");
       }
   }
   

   import org.springframework.context.annotation.Configuration;
   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.WebSocketHandler;
   import org.springframework.web.socket.server.support.HttpSessionHandshakeInterceptor;

   @Configuration
   @EnableWebSocket
   public class WebSocketConfig implements WebSocketConfigurer {

       private final WebSocketHandler webSocketHandler;

       public WebSocketConfig(WebSocketHandler webSocketHandler) {
           this.webSocketHandler = webSocketHandler;
       }

       @Override
       public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
           registry.addHandler(webSocketHandler, "/ws/chat")
                   .addInterceptors(new HttpSessionHandshakeInterceptor())
                   .setAllowedOrigins("*");
       }
   }
