Spring最近刚刚推出了SpringAI封装了AI大模型接口的使用。本文将参考Spring官网案例一步步教你如何调用OpenAI的接口让ChatGPT接口返回一个笑话。
前提条件
请下载并安装好JDK17或更新的版本本文使用的是JDK21。JDK下载地址。准备好梯子。没有梯子调用OpenAI接口会报500错误。也别问我梯子是啥懂得都懂。准备好OpenAI接口的API Key淘宝上有卖的应该不差过10元。如果你的Maven用的是阿里云仓库建议先注释掉。AI依赖包太新了目前阿里云还没有。
创建项目 使用idea创建一个新的Spring项目。File New Project Spring Initializer Server URL一定要用Spring的https://start.spring.io其他的地址目前还没更新。 JDK版本一定要大于等于17低版本不支持Springboot3 依赖包选择Spring Web和OpenAI在最下方如下图 创建成功之后等待项目自动下载依赖包。这里就看大家网速了。
配置开发 项目创建好之后加入OpenAI接口配置。 application.properties spring.application.nameJavaAI
# openai api-key 没有的建议自己去买一个我这个应该很快就会失效
spring.ai.openai.api-keysk-YBp5UzXATs19YDXrnkIRT3BlbkFJcjUcXqcdCLSxNpbUR4Ts
# ChatGPT模型版本
spring.ai.openai.chat.options.modelgpt-3.5-turbo
spring.ai.openai.chat.options.temperature0.7pom.xml这里面的内容是自动生成的一般不用改。 ?xml version1.0 encodingUTF-8?

/project在你的启动类中加入代理设置不然掉接口会报500。 JavaAiApplication.java import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;SpringBootApplication
public class JavaAiApplication {public static void main(String[] args) {// 设置代理这里需要根据自己找的代理软件来调整配置System.setProperty(proxySet,true);System.setProperty(proxyType,4);// 代理地址根据代理软件System.setProperty(proxyHost, 127.0.0.1);// 代理端口HttpSystem.setProperty(proxyPort,21882);SpringApplication.run(JavaAiApplication.class, args);}
}创建controller使用调用OpenAI的接口。 ChatController import org.springframework.ai.chat.ChatResponse;
import org.springframework.ai.chat.messages.UserMessage;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.openai.OpenAiChatClient;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
import reactor.core.publisher.Flux;import java.util.Map;/*** ChatGPT接口调用br** author Gem* version 1.0* date 2024/4/18*/
RestController
public class ChatController {private final OpenAiChatClient chatClient;Autowiredpublic ChatController(OpenAiChatClient chatClient) {this.chatClient chatClient;}GetMapping(/ai/generate)public Map generate(RequestParam(value message, defaultValue Tell me a joke) String message) {return Map.of(generation, chatClient.call(message));}GetMapping(/ai/generateStream)public FluxChatResponse generateStream(RequestParam(value message, defaultValue Tell me a joke) String message) {Prompt prompt new Prompt(new UserMessage(message));return chatClient.stream(prompt);}
}到此开发配置结束。
启动调试 启动项目启动前请先开启梯子默认端口号8080。 启动成功日志 Connected to the target VM, address: 127.0.0.1:55997, transport: socket. ____ _ __ _ _/\\ / ____ __ _ _(_)_ __ __ _ \ \ \ \
