javax.websocket.DeploymentException: Multiple Endpoints may not be deployed to the same path [/websocket/{sid}] : existing endpoint was class com.sanyi.qibaobusiness.framework.webSocket.WebSocketServe

报错：

javax.websocket.DeploymentException: Multiple Endpoints may not be deployed to the same path [/websocket/{sid}] : existing endpoint was class com.sanyi.qibaobusiness.framework.webSocket.WebSocketServer and new endpoint is class com.sanyi.qibaobusiness.framework.webSocket.WebSocketServer

原因tomcat集成websocket不需要自己集成WebSocketConfig

删除项目中的 WebSocketConfig

下面的代码是原来集成的，注释掉就好了。

@Configuration
public class WebSocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }
}
