我想在ESP32上使用websocket与java websocket服务器通信。我正在使用ESP32文档中的代码示例： https://github.com/espressif/esp-idf/tree/a45e99853/examples/protocols/websocket

我调整的是ssid名称和密码以及websocket端点地址。我的Java代码如下：

package com.webapp.ws;

import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.websocket.OnError;
import javax.websocket.Onmessage;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;

@ServerEndpoint("/hello")
public class HelloEndpoint {
    private Session session;

    @OnOpen
    public void onCreateSession(Session session){
        System.out.println("Connected " + session.toString());
        this.session = session;
    }

    @Onmessage
    public void OnTextMessage(String message){
        System.out.println("message=" + message);
        if(this.session != null && this.session.isOpen()){
            try {
                System.out.println("received: " + message);
                this.session.getBasicRemote().sendText("From server: " + message);
            } catch (IOException ex) {
                Logger.getLogger(HelloEndpoint.class.getName()).log(Level.SEVERE,null,ex);
            }
        }
    }

    @OnError
    public void onError(Session session,Throwable thr) {
        Logger.getLogger(HelloEndpoint.class.getName()).log(Level.SEVERE,thr.toString());

    }
}

不幸的是，我无法获得esp和java（托管在tomee上）之间的通信。来自ESP的日志如下：

在tomcat日志上，我只能看到已创建新连接，仅此而已。这意味着不会随时调用Onmessage注释。

有人可以帮助我解决这个问题吗？
