스프링 websocket 얻는 404 찾을 수 없습니다.

Question

봄 websocket 끝점을 만들려고합니다. 그러나 클라이언트 측에서 연결을 시도 할 때마다 404가 표시됩니다.

@ServerEndpoint(value = "/websocket") 

이 좋은 Java 구현도 있습니다. 아래는 작동하지 않는 스프링 구현 코드입니다. 여기서 내가 뭘 잘못하고 있니? 아래

package com.tlab.endpoint; 

import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.web.socket.WebSocketHandler; 
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 implements WebSocketConfigurer { 

    @Override 
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) { 
     registry.addHandler(socketHandler(),"/socket");; 
    } 

    @Bean 
    public WebSocketHandler socketHandler() { 
     return new SocketHandler(); 
    } 

} 

내가 모든/휴식/소켓 핸들러

var websocket = new WebSocket("ws://localhost:8080/tsim/socket"); 
var websocket = new WebSocket("ws://localhost:8080/tsim/socket"); 
var websocket = new WebSocket("ws://localhost:8080/tsim/rest/socket"); 

에/소켓 가능한 조합

을 diff를 시도 클라이언트 측 코드에서 핸들러

package com.tlab.endpoint; 

import org.springframework.web.socket.TextMessage; 
import org.springframework.web.socket.WebSocketSession; 
import org.springframework.web.socket.handler.TextWebSocketHandler; 


public class SocketHandler extends TextWebSocketHandler { 

    @Override 
    public void handleTextMessage(WebSocketSession session, TextMessage message) { 

    } 

} 

입니다 처리기 내

var websocket = new WebSocket("ws://localhost:8080/tsim/rest/socket"); 

여기서 tsim은 나의 컨텍스트 루트입니다. 모든 것은 아래의 오류를 던졌습니다

WebSocket connection to 'ws://localhost:8080/tsim/socket' failed: Error during WebSocket handshake: Unexpected response code: 404. 

컴파일 및 배포 오류가 발생하지 않았습니다. 내가 바람둥이 8.0을 사용하고 아래 디스패처 서블릿 구성입니다.

    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/rest/</url-pattern> 
</servlet-mapping> 

Answer 1

마침내 자신 해답을 찾을 수 있습니다. Dispatcher 서블릿이 정상적인 http 요청으로 처리하므로 @Controller 주석을 WebSocketConfig 클래스에 추가해야합니다.

@Configuration 
@EnableWebSocket 
@Controller 
public class WebSocketConfig implements WebSocketConfigurer 

Answer 2

제 경우, 디스패처 서블릿 매핑에 문제가 있습니다. 나는 단지 * .mvc 매핑을했고, 웹 소켓은하지 않고, 그래서 나는 변경했다 : // localhost를 : 8080/침/당신의 예에서 socket`하지만 오류 메시지

<servlet-mapping> 
    <servlet-name>dispatcherServlet</servlet-name> 
    <url-pattern>*.mvc</url-pattern> 
    <url-pattern>/</url-pattern> 
    </servlet-mapping>
