package com.example.mychatgpt;

import org.apache.juli.logging.Log;

import org.yeauty.annotation.*;
import org.yeauty.pojo.Session;

import java.io.IOException;
import java.util.Map;

@serverendpoint(path = "/ws", host = "0.0.0.0", port = "8888")
public class MyWebSocket {

@OnOpen
public void onOpen(Session session, HttpHeaders headers, @RequestParam String req, @RequestParam MultiValueMap reqMap, @PathVariable String arg, @PathVariable Map pathMap) {
    System.out.println("new connection");
    System.out.println(req);
}

@OnClose
public void onClose(Session session) throws IOException {
    System.out.println("one connection closed");
}

@OnError
public void onError(Session session, Throwable throwable) {
    System.out.println("出现错误");
    throwable.printStackTrace();
}

@OnMessage
public void onMessage(Session session, String message) {
    System.out.println("接收到消息");
    System.out.println(message);
    session.sendText("Hello Netty!");
}

@OnBinary
public void onBinary(Session session, byte[] bytes) {
    System.out.println("接收到二进制信息");
    for (byte b : bytes) {
        System.out.println(b);
    }
    session.sendBinary(bytes);
}

@OnEvent
public void onEvent(Session session, Object evt) {
    if (evt instanceof IdleStateEvent) {
        IdleStateEvent idleStateEvent = (IdleStateEvent) evt;
        switch (idleStateEvent.state()) {
            case READER_IDLE:
                System.out.println("read idle");
                break;
            case WRITER_IDLE:
                System.out.println("write idle");
                break;
            case ALL_IDLE:
                System.out.println("all idle");
                break;
            default:
                break;
        }
    }
}

}

我把
@BeforeHandshake
public void handshake(Session session, HttpHeaders headers, @RequestParam String req, @RequestParam MultiValueMap reqMap, @PathVariable String arg, @PathVariable Map pathMap){
session.setSubprotocols("stomp");
if (!"ok".equals(req)){
System.out.println("Authentication failed!");
session.close();
}
}
这段删除了，因为有这一段，客户端就一直连接中无法成功，也不报错。。。但是删除了能连接上但是就一直报错。。。

mvn打下dependency列表 贴出来看看

[BraveSLC]

注释掉这些或者改成自己的逻辑

if (!"ok".equals(req)){
System.out.println("Authentication failed!");
session.close();
