Question

我在现有的Web应用程序中设置websocket配置时遇到了问题。

@Configuration
@EnableWebSocketMessageBroker
public class WebsocketConfig extends AbstractWebSocketMessageBrokerConfigurer{

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/mobile");
        config.setApplicationDestinationPrefixes("/mobile-server");
        config.setUserDestinationPrefix("/mobile-user");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/mobile-socket")
        .withSockJS()
        .setInterceptors(new HttpSessionHandshakeInterceptor());
    }
}

控制器

@Controller
public class WebSocketInboxController{

    @MessageMapping("/inbox")
    @SendToUser("/mobile")
    public Map<String,Object> inbox(
    ){

        Map<String,Object> res = new HashMap<>();

        res.put("hello", "hello");

        return res;
    }

客户端

const webstomp = require('webstomp-client');

const socket = webstomp.client('ws://www.dev.server.com/mobile-socket',{
  debug:true
});

socket.connect('marc@gmail.com', '123456', (client) => {
  console.log('connected');

  socket.send("/mobile-server/inbox",)
  socket.subscribe("/mobile/inbox");
}, (client, err) => {
  console.log(err);
});

我在客户端尝试连接时看到的是Spring尝试将/ mobile-socket与现有Web应用程序的RequestMappings进行匹配，最后通过@RequestMapping（“/ {somevar}”找到匹配它的那个）。

我是WebSockets的新手，但我希望端点注册能成为这类连接的主要内容吗？

即使删除了错误的RequestMapping被击中，我也似乎无法触及MessageMapping。我在日志中看到了这个

Spring尝试将“/ mobile-socket”与RequestMappings进行匹配，因为所有请求都转到Web应用程序上下文中的HandlerMapping bean，以将传入的Web请求映射到适当的处理程序。随着带注释的控制器的引入，RequestMappingHandlerMapping自动在所有@Controller bean上查找@RequestMapping注释，包括具有@MessageMapping的控制器。

由于@MessageMapping只能在@Controller注释下定义，因此Spring会尝试匹配其他RequestMappings。

一种可能的解决方案是引入拦截器来处理websocket请求URL以专门映射到特定控制器。你可以尝试一下！

Spring Websocket url命中RequestMapping但不是MessageMapping
