SpringBoot代码

当然我只做了一个简易版的AI对话，你可以在我的基础之上进行改动

引入库

        </dependency>

controller

package com.xinggui.demo.controller;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@Slf4j
@CrossOrigin(origins = "http://127.0.0.1:5500") // 假设前端在3000端口运行
public class test {
    @PostMapping("/test")
    public Response test(String problem){
        if(problem.length() == 0){
            return new Response("-1","请输入问题",null);
        }
        String result = null;
        try {
            result = ApiTestUtil.getProblem(problem);
        } catch (NoApiKeyException e) {
            log.error("apiKey错误");
        } catch (InputRequiredException e) {
            log.error("输入为空");
        }
        return new Response("0","success",result);
    }
}

返回对象类

这里我使用VScode中的liveServer插件，启动项目

后端对http://127.0.0.1:5500做了跨域配置

效果展示

这里还添加了一个Loading效果
