ChatGPT-Java是一款支援開箱即用的OpenAI Java SDK。目前以支援官網全部Api。我們贊成使用最新版本的GPT-3.5-Turbo和whisper-1模型。
2.Spring Boot是由Pivotal團隊提供的全新框架，其設計目的是用來簡化新Spring應用的初始搭建以及開發過程。這個框架採用特定的配置方式，無需開發人員再定義通用配置。透過這種方式，Spring Boot致力於在蓬勃發展的快速應用開發領域(rapid application development)成為領導者。
3.ChatUI Pro 是在ChatUI 基礎元件的基礎上，結合阿里小蜜的最佳實踐，沉澱和總結出來的一個開箱即用的，可快速搭建智慧對話機器人的框架。它簡單易上手，透過簡單的配置就能搭建出對話機器人；同時它強大易擴展，透過豐富的介面和自訂卡片滿足各種客製化需求。
本專案採用了GPT-3.5-Turb模型作為基礎，透過springboot結合redis、chat-java以及chatUI Pro實現簡單的人工智慧機器人。因為存取openAI的API回傳結果比較慢，專案中當前端將問題請求傳送到後端後，後端會將產生一個UUID，傳回前端，同時後端也會重新開啟一個執行緒去存取openAI，當openAI回傳結果後，後端將UUID做為key，openAI回傳的結果做為value儲存到redis。前端會根據後端第一次請求的結果中UUID做為參數每個5s請求一次後端的answer接口，answer接口會根據UUID查詢redis是否有值，直到後端answer接口返回結果後前端將結果輸出給使用者
1.建立springboot項目，項目命名mychatgpt。
2.導入專案pom的依賴

package com.xyh.mychatgpt.utils;
import com.unfbx.chatgpt.OpenAiClient;
import com.unfbx.chatgpt.entity.chat.ChatChoice;
import com.unfbx.chatgpt.entity.chat.ChatCompletion;
import com.unfbx.chatgpt.entity.chat.Message;
import com.unfbx.chatgpt.entity.common.Choice;
import com.unfbx.chatgpt.entity.completions.Completion;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
import java.util.Arrays;
import java.util.List;
/**
* @author xiangyuanhong
* @description: TODO
* @date 2023/3/21上午9:28
*/
@Component
public class ChatGPTUtils {
@Value("${xyh.openai.key}")
private String token;
@Autowired
private RedisUtils redisUtils;
public void ask(String model,String question,String uuid){
StringBuffer result=new StringBuffer();
try {
OpenAiClient openAiClient = new OpenAiClient(token, 3000, 300, 300, null);
if("GPT-3.5-Turb".equals(model)){
// GPT-3.5-Turb模型
Message message=Message.builder().role(Message.Role.USER).content(question).build();
ChatCompletion chatCompletion = ChatCompletion.builder().messages(Arrays.asList(message)).build();
List<ChatChoice> resultList = openAiClient.chatCompletion(chatCompletion).getChoices();
for (int i = 0; i < resultList.size(); i++) {
result.append(resultList.get(i).getMessage().getContent());
}
}else{
//text-davinci-003/text-ada-003
Completion completion = Completion.builder()
.prompt(question)
.model(model)
.maxTokens(2000)
.temperature(0)
.echo(false)
.build();
Choice[] resultList = openAiClient.completions(completion).getChoices();
for (Choice choice : resultList) {
result.append(choice.getText());
}
}
}catch (Exception e) {
System.out.println(e.getMessage());
result.append("小爱还不太懂，回去一定努力学习补充知识");
}
redisUtils.set(uuid,result.toString());
}
}4.開發專案Controller類，用來與前端互動
package com.xyh.mychatgpt.controller;
import cn.hutool.core.thread.ThreadUtil;
import cn.hutool.core.util.IdUtil;
import cn.hutool.core.util.StrUtil;
import com.xyh.mychatgpt.utils.ChatGPTUtils;
import com.xyh.mychatgpt.utils.R;
import com.xyh.mychatgpt.utils.RedisUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import javax.servlet.http.HttpServletRequest;
/**
* @author xiangyuanhong
* @description: TODO
* @date 2023/2/28下午4:57
*/
@RestController
public class IndexController {
@Autowired
private RedisUtils redisUtils;
@Autowired
private ChatGPTUtils chatGPTUtils;
@GetMapping("/ask")
public R ask(String question,HttpServletRequest request) {
String uuid=IdUtil.simpleUUID();
if (StrUtil.isBlank(question)) {
question = "今天天气怎么样？";
}
String finalQuestion = question;
ThreadUtil.execAsync(()->{
chatGPTUtils.ask("GPT-3.5-Turb", finalQuestion,uuid);
});
return R.ok().put("data",uuid);
}
@GetMapping("/answer")
public R answer(String uuid){
String result=redisUtils.get(uuid);
return R.ok().put("data",result);
}
}5.前端頁面開發，在專案templates目錄建立index.html頁面，並引入chatUI pro相關檔案
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta name="renderer" content="webkit" />
<meta name="force-rendering" content="webkit" />
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />

<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=0, minimum-scale=1.0, maximum-scale=1.0, viewport-fit=cover" />
<title>滴答小爱</title>
<link rel="stylesheet" href="//g.alicdn.com/chatui/sdk-v2/0.2.4/sdk.css" rel="external nofollow" >
</head>
<body>
<div id="root"></div>

<script src="js/jquery-3.6.3.min.js"></script>
<script src="//g.alicdn.com/chatui/icons/0.3.0/index.js" async></script>
</body>
</html>6.建立setup.js實作chatUI Pro與後端通訊交換。
var bot = new ChatSDK({
config: {
// navbar: {
// title: '滴答小爱'
// },
robot: {
avatar: 'images/chat.png'
},
// 用户头像
user: {
avatar: 'images/user.png',
},
// 首屏消息
messages: [
{
type: 'text',
content: {
text: '您好，小爱为您服务，请问有什么可以帮您的？'
}
}
],
// 快捷短语
// quickReplies: [
// { name: '健康码颜色',isHighlight:true },
// { name: '入浙通行申报' },
// { name: '健康码是否可截图使用' },
// { name: '健康通行码适用范围' },
// ],
// 输入框占位符
placeholder: '输入任何您想询问的问题',
},
requests: {
send: function (msg) {
if (msg.type === 'text') {
return {
url: '/ask',
data: {
question: msg.content.text
}
};
}
}
},
handlers: {
/**
*
* 解析请求返回的数据
* @param {object} res - 请求返回的数据
* @param {object} requestType - 请求类型
* @return {array}
*/
parseResponse: function (res, requestType) {
// 根据 requestType 处理数据
if (requestType === 'send' && res.code==0) {
// 用 isv 消息解析器处理数据
$.ajaxSettings.async=false;
var answer="";
var isOK=false;
while(!isOK){
$.get("/answer",{uuid:res.data},function(result){
console.log(result.data)
if(null != result.data){
isOK=true;
answer=result.data;
}
},"json");
if(!isOK){
sleep(5000);
}
}
$.ajaxSettings.async=true;
return [{"_id":res.data,type:"text",content:{text:answer},position:"left"}];
}
},
},
});
function sleep(n) { //n表示的毫秒数
var start = new Date().getTime();
while (true) {
if (new Date().getTime() - start > n) {
break;
}
}
}
bot.run();一旦完成專案搭建，啟動 Spring Boot 專案並造訪 http://ip: 埠 即可。專案最終效果：http://hyrun.vip/
