WebSocket connection to 'ws://localhost/dev-api/websocket-service/wsService?

WebSocket连接到'ws://localhost/dev-api/websocket-service/wsService?'是该项目中的一个WebSocket连接地址。在项目配置中，使用了代理来将以'/api'开头的请求转发到'http://127.0.0.1:8888'，同时开启了WebSocket支持。因此，'ws://localhost/dev-api/websocket-service/wsService?'实际上是指向'http://127.0.0.1:8888/websocket-service/wsService?'的WebSocket连接地址。这个地址用于与后端建立WebSocket连接，以实现实时通信功能，例如聊天、直播、模拟面试和弹幕互动等功能。

Springboot配置Websocket，前端提示WebSocket connection to ws://localhost:8080/* failed

这个问题通常是由于WebSocket连接配置不正确或者后台没有正确的处理WebSocket请求造成的。下面是一个基本的Spring Boot WebSocket配置示例：

首先，确保您已经添加了Spring WebSocket依赖项：

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-websocket</artifactId>
    </dependency>
</dependencies>

然后，创建一个WebSocket配置类，例如：

@Configuration
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new MyWebSocketHandler(), "/websocket").setAllowedOrigins("*");
    }
}

上面的代码中，我们注册了一个名为`MyWebSocketHandler`的WebSocket处理程序，并将它映射到路径`/websocket`。`setAllowedOrigins("*")`允许所有来源的WebSocket连接。

最后，在前端，确保您使用了正确的WebSocket URL。如果您的后台应用程序运行在`localhost:8080`上，则WebSocket URL应该是`ws://localhost:8080/websocket`。

如果您仍然遇到问题，请检查后台应用程序的日志，看看是否有任何错误消息。

webSocket connection to 'ws://localhost:8081/my-websocket' failed:

There could be multiple reasons for the webSocket connection failure. Here are some possible causes:
- The server is not running or is not listening on the specified port (8081 in this case).
- The URL is incorrect or malformed.
- The connection is blocked by a firewall or network restriction.
- The client or server code has a bug that prevents the connection from establishing.

To troubleshoot the issue, you can try the following steps:
- Check if the server is running and listening on the correct port.
- Verify the URL syntax and make sure it matches the server configuration.
- Check if there are any firewall rules or network restrictions that block the connection.
- Debug the client or server code to identify any bugs or errors that prevent the connection.
