spring Ai框架调用openai大模型简易demo_spring ai demo

前提：
需要科学上网，key没有官方的，就找中转的key

1 pom依赖，注意添加的依赖和仓库配置

2 yml配置，如果是官方key，base-url就不用填了

spring:
  ai:
    openai:
      base-url: https://xxxxx
      api-key: xxxxxxx
      chat:
        options:
          model: gpt-3.5-turbo
          temperature: 0.6

3 测试调用

import org.springframework.ai.chat.ChatResponse;
import org.springframework.ai.chat.prompt.Prompt;
import org.springframework.ai.openai.OpenAiChatClient;
import org.springframework.ai.openai.OpenAiChatOptions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
@RequestMapping("/openai")
public class AiController_1 {
 
    @Autowired
    private OpenAiChatClient openAiChatClient;
 
    @RequestMapping("/chart_1")
    public Object chart_1() {
        String call = openAiChatClient.call("随便说点什么,10个字以内");
        return call;
    }
 
    @RequestMapping("/chart_2")
    public Object chart_2(String message) {
        //代码中配置，会覆盖application.yml中的配置
        Prompt prompt = new Prompt(
                message,
                OpenAiChatOptions.builder()
                        .withModel("gpt-3.5-turbo") //大模型用哪个
                        .withTemperature(0.9f) //温度高，更发散,准确性降低，温度低，更保守，准确性高
                        .build());
 
        ChatResponse call = openAiChatClient.call(prompt);
        return call.getResult().getOutput();
    }
 
}
