我想创建一个websocket端点与春天。但每当我试图从客户端连接,我得到了404。我也有一个Java实现与春天websocket 404找不到

@ServerEndpoint(value = "/websocket") 

它工作良好。下面是我的春天实施代码不起作用。我在这里做错了什么?

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

是处理程序

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) { 

    } 

} 

在客户端侧的代码我尝试了所有diff的可能的组合

与/插座在处理程序

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"); 

与/休息/插座in handler

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

其中tsim是我的根。一切抛出以下错误

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

我没有得到任何编译和部署错误。我使用tomcat 8.0及以下版本是调度程序servlet配置。下面

你给'WS://本地主机:8080 /尖沙咀/ socket'在你的例子,但错误信息显示'ws:// localhost:8080/TradeSim/socket'。它是'tsim'还是'TradeSim'? – Bogdan

我尝试了不同的方式..我将其作为tsim或TradeSim将其作为contextroot进行覆盖。为避免混淆,我将对其进行编辑 – anandaravindan

我终于找到了自己的答案。由于这是由调度程序servlet作为普通的http请求处理的。我需要注解@Controller添加到WebSocketConfig类

@Configuration 
@EnableWebSocket 
@Controller 
public class WebSocketConfig implements WebSocketConfigurer

我使用的是spring引导并具有相同的问题,但是向WebSocketConfig添加@Controller doesn'帮助。令人惊讶的是我得到了403分。你能帮我吗? – Greyshack

找到修复程序。如果你想用浏览器测试websocket,你需要添加registry.addHandler(socketHandler(),“/ socket”)。setAllowedOrigins(“*”); – Greyshack

我我的情况下,问题是调度servlet映射。我只考了* .mvc映射和WebSocket的是没有了,所以我不得不改变:

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