春天websocket 404找不到

Question

我想創建一個websocket端點與春天。但每當我試圖從客戶端連接，我得到了404。我也有一個Java實現與

@ServerEndpoint(value = "/websocket") 

它工作良好。下面是我的春天實施代碼不起作用。我在這裏做錯了什麼？

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(); 
    } 

} 

下面

是處理程序

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) { 

    } 

} 

在客戶端側的代碼我嘗試了所有diff的可能的組合

與/插座在處理程序

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"); 

與/休息/插座in handler

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

其中tsim是我的根。一切拋出以下錯誤

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

我沒有得到任何編譯和部署錯誤。我使用tomcat 8.0及以下版本是調度程序servlet配置。下面

    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

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

Answer 1

我終於找到了自己的答案。由於這是由調度程序servlet作爲普通的http請求處理的。我需要註解@Controller添加到WebSocketConfig類

@Configuration 
@EnableWebSocket 
@Controller 
public class WebSocketConfig implements WebSocketConfigurer 

Answer 2

我我的情況下，問題是調度servlet映射。我只考了* .mvc映射和WebSocket的是沒有了，所以我不得不改變：

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