springboot websocket @MessageMapping注解不生效

Question

@Controller
public class WsController {

    @MessageMapping("ws/chat")
    public void handleChat(@Header("destination") String destination) throws Exception
    {
        System.out.println(destination);
    }

}

java springboot 使用websocket实现在线聊天，添加@MessageMapping("ws/chat")注解之后handleChat方法显示Method 'handleChat(java.lang.String)' is never used从未被调用，
websocket连接正常，消息发送也正常：

打开浏览器f12可见
<<< CONNECTED
version:1.1
heart-beat:0,0

>>> SEND
destination:http://localhost:8082/ws.chat
content-length:12

哈哈哈哈

Answer 1

@MessageMapping中的路径配置有没有写错？你的Feign跟这个有没有冲突？
