            //todo 将问答信息入库进行记录，可自行实现
        }
    }

        //需要开启一个新的线程来执行netty server 服务器
        new Thread(() -> {
            try {
                start();
                log.info("消息推送线程开启！");
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }).start();
    }
}

2）在handler目录下新建handler类

package com.example.xunfeigpt.netty.handler;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;

import com.example.xunfeigpt.bean.NettyGroup;
import com.example.xunfeigpt.bean.ResultBean;
import com.example.xunfeigpt.service.PushService;
import io.netty.channel.ChannelHandler;
import io.netty.channel.ChannelHandlerContext;
import io.netty.channel.SimpleChannelInboundHandler;
import io.netty.handler.codec.http.websocketx.TextWebSocketFrame;
import io.netty.util.AttributeKey;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Slf4j
@Component
@ChannelHandler.Sharable
public class WebSocketHandler extends SimpleChannelInboundHandler<TextWebSocketFrame> {
    @Autowired
    private PushService pushService;

    @Override
    public void handlerAdded(ChannelHandlerContext ctx) throws Exception {
        log.info("handlerAdded被调用,{}", JSON.toJSONString(ctx));
        //todo 添加校验功能，校验合法后添加到group中

        // 添加到channelGroup 通道组
        NettyGroup.getChannelGroup().add(ctx.channel());
    }

    @Override
    protected void channelRead0(ChannelHandlerContext ctx, TextWebSocketFrame msg) throws Exception {
        log.info("服务器收到消息：{}", msg.text());
        // 获取用户ID,关联channel
        JSONObject jsonObject = JSON.parseObject(msg.text());
        String channelId = jsonObject.getString("uid");

        // 将用户ID作为自定义属性加入到channel中，方便随时channel中获取用户ID
        AttributeKey<String> key = AttributeKey.valueOf("userId");
        //String channelId = CharUtil.generateStr(uid);
        NettyGroup.getUserChannelMap().put(channelId, ctx.channel());
        boolean containsKey = NettyGroup.getUserChannelMap().containsKey(channelId);
        //通道已存在，请求信息返回
        if (containsKey) {
            //接收消息格式{"uid":"123456","text":"中华人民共和国成立时间"}
            String text = jsonObject.getString("text");
            //请求大模型服务器，获取结果
            ResultBean resultBean = pushService.pushMessageToXFServer(channelId, text);
            String data = (String) resultBean.getData();
            //推送
            pushService.pushToOne(channelId, JSON.toJSONString(data));
        } else {
            ctx.channel().attr(key).setIfAbsent(channelId);
            log.info("连接通道id:{}", channelId);
            // 回复消息
            ctx.channel().writeAndFlush(new TextWebSocketFrame(JSON.toJSONString(ResultBean.success(channelId))));
        }
    }

    @Override
    public void handlerRemoved(ChannelHandlerContext ctx) throws Exception {
        log.info("handlerRemoved被调用,{}", JSON.toJSONString(ctx));
        // 删除通道
        NettyGroup.getChannelGroup().remove(ctx.channel());
        removeUserId(ctx);
    }

    @Override
    public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) throws Exception {
        log.info("通道异常：{}", cause.getMessage());
        // 删除通道
        NettyGroup.getChannelGroup().remove(ctx.channel());
        removeUserId(ctx);
        ctx.close();
    }

    private void removeUserId(ChannelHandlerContext ctx) {
        AttributeKey<String> key = AttributeKey.valueOf("userId");
        String userId = ctx.channel().attr(key).get();
        NettyGroup.getUserChannelMap().remove(userId);
    }
}

5、在service目录下
1）新建PushService接口

import com.example.xunfeigpt.bean.ResultBean;

public interface PushService {
    void pushToOne(String uid, String text);

    void pushToAll(String text);

    ResultBean pushMessageToXFServer(String uid, String text);
}

2）在impl文件夹下新建PushServiceImpl类

package com.example.xunfeigpt.service.impl;

import com.alibaba.fastjson.JSON;

import com.example.xunfeigpt.bean.NettyGroup;
import com.example.xunfeigpt.bean.ResultBean;
import com.example.xunfeigpt.bean.RoleContent;
import com.example.xunfeigpt.config.XFConfig;
import com.example.xunfeigpt.listener.XFWebClient;
import com.example.xunfeigpt.listener.XFWebSocketListener;
import com.example.xunfeigpt.service.PushService;
import io.netty.channel.Channel;
import io.netty.handler.codec.http.websocketx.TextWebSocketFrame;
import lombok.extern.slf4j.Slf4j;
import okhttp3.WebSocket;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;

import java.util.ArrayList;
import java.util.concurrent.ConcurrentHashMap;

@Slf4j
@Service
public class PushServiceImpl implements PushService {
    @Autowired
    private XFConfig xfConfig;

    @Autowired
    private XFWebClient xfWebClient;

    @Override
    public void pushToOne(String uid, String text) {
        if (StringUtils.isEmpty(uid) || StringUtils.isEmpty(text)) {
            log.error("uid或text均不能为空");
            throw new RuntimeException("uid或text均不能为空");
        }
        ConcurrentHashMap<String, Channel> userChannelMap = NettyGroup.getUserChannelMap();
        for (String channelId : userChannelMap.keySet()) {
            if (channelId.equals(uid)) {
                Channel channel = userChannelMap.get(channelId);
                if (channel != null) {
                    ResultBean success = ResultBean.success(text);
                    channel.writeAndFlush(new TextWebSocketFrame(JSON.toJSONString(success)));
                    log.info("信息发送成功：{}", JSON.toJSONString(success));
                } else {
                    log.error("该id对于channelId不存在！");
                }
                return;
            }
        }
        log.error("该用户不存在！");
    }

    @Override
    public void pushToAll(String text) {
        String trim = text.trim();
        ResultBean success = ResultBean.success(trim);
        NettyGroup.getChannelGroup().writeAndFlush(new TextWebSocketFrame(JSON.toJSONString(success)));
        log.info("信息推送成功：{}", JSON.toJSONString(success));
    }

    //测试账号只有2个并发，此处只使用一个，若是生产环境允许多个并发，可以采用分布式锁
    @Override
    public synchronized ResultBean pushMessageToXFServer(String uid, String text) {
        RoleContent userRoleContent = RoleContent.createUserRoleContent(text);
        ArrayList<RoleContent> questions = new ArrayList<>();
        questions.add(userRoleContent);
        XFWebSocketListener xfWebSocketListener = new XFWebSocketListener();
        WebSocket webSocket = xfWebClient.sendMsg(uid, questions, xfWebSocketListener);
        if (webSocket == null) {
            log.error("webSocket连接异常");
            ResultBean.fail("请求异常，请联系管理员");
        }
        try {
            int count = 0;
            int maxCount = xfConfig.getMaxResponseTime() * 5;
            while (count <= maxCount) {
                Thread.sleep(200);
                if (xfWebSocketListener.isWsCloseFlag()) {
                    break;
                }
                count++;
            }
            if (count > maxCount) {
                return ResultBean.fail("响应超时，请联系相关人员");
            }
            return ResultBean.success(xfWebSocketListener.getAnswer());
        } catch (Exception e) {
            log.error("请求异常：{}", e);
        } finally {
            webSocket.close(1000, "");
        }
        return ResultBean.success("");
    }
}

6、测试controller

import com.example.xunfeigpt.bean.ResultBean;
import com.example.xunfeigpt.service.PushService;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@Slf4j
@RestController
@RequestMapping("/xfModel")
public class XFMessageController {
    @Autowired
    private PushService pushService;

    @GetMapping("/test")
    public ResultBean test(String uid, String text) {
        if (StringUtils.isEmpty(uid) || StringUtils.isEmpty(text)) {
            log.error("uid或text不能为空");
            return ResultBean.fail("uid或text不能为空");
        }
        return pushService.pushMessageToXFServer(uid, text);
    }
}

7、websocket测试
