集成websocket、gateway时老是提示访问地址404，麻烦帮忙查看

修改 blade-demo模块

pom文件增加依赖

    org.springframework.boot
    spring-boot-starter-websocket

增加WebSocketAutoConfig 文件

package com.example.demo.config;
 
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.simp.config.MessageBrokerRegistry;
import org.springframework.web.socket.config.annotation.EnableWebSocketMessageBroker;
import org.springframework.web.socket.config.annotation.StompEndpointRegistry;
import org.springframework.web.socket.config.annotation.WebSocketMessageBrokerConfigurer;
 
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketAutoConfig implements WebSocketMessageBrokerConfigurer {
 
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/bullet","/websocket")     //开启/bullet端点
                .setAllowedOrigins("*")             //允许跨域访问
                .withSockJS();                      //使用sockJS
    }
 
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
 
        //订阅Broker名称
        //registry.enableSimpleBroker("/topic","/user");
        registry.enableSimpleBroker("/toAll","/topic");
        //全局使用的订阅前缀（客户端订阅路径上会体现出来）
        //registry.setApplicationDestinationPrefixes("/app/");
        //
        //点对点使用的订阅前缀（客户端订阅路径上会体现出来），不设置的话，默认也是/user/
        //registry.setUserDestinationPrefix("/user/");
    }
}

增加BulletController

package com.example.demo.controller;
 
import com.example.demo.dto.BulletMessageDTO;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.messaging.handler.annotation.MessageMapping;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.messaging.simp.SimpMessagingTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
 
@Controller
public class BulletController {
 
    private static final Logger logger=LoggerFactory.getLogger(BulletController.class);
    @MessageMapping("/hellowebsocket")
    //SendTo 发送至 Broker 下的指定订阅路径
    @SendTo("/topic/helloworld")
//    @SendTo("/toAlltoAll/bulletScreen")
    public String say(BulletMessageDTO clientMessage) {
        //方法用于广播测试
        if (clientMessage!=null){
            if (clientMessage.getMessage()!=null){
                clientMessage.setMessage(clientMessage.getMessage().trim());
            }
        }
        logger.info(clientMessage.getUsername()+":"+clientMessage.getMessage());
        return clientMessage.getMessage();
    }
 
    //注入SimpMessagingTemplate 用于点对点消息发送
    @Autowired
    private SimpMessagingTemplate messagingTemplate;
 
    @RequestMapping("/send")
    public void send(String msg){
        messagingTemplate.convertAndSend("/topic/helloworld", msg + "hello!!!");
    }
 
}

增加blade-gateway 网关配置文件

{
"name": "Path",
