Spring Boot 整合 Spring AI 实现项目接入ChatGPT(OpenAl的调用）

import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
import com.openai.api.AskCompletionResponse;
import com.openai.api.Completions;
import com.openai.api.EngineApi;
import com.openai.api.ModelApi;
import com.openai.api.OpenaiService;
 
@RestController
public class ChatController {
 
    private final OpenaiService openaiService;
 
    public ChatController(OpenaiService openaiService) {
        this.openaiService = openaiService;
    }
 
    @PostMapping("/completions")
    public AskCompletionResponse generateCompletion(@RequestBody CompletionRequest completionRequest) {
        Completions completions = Completions.builder()
                .model(completionRequest.getModel())
                .prompt(completionRequest.getPrompt())
                .maxTokens(completionRequest.getMaxTokens())
                .temperature(completionRequest.getTemperature())
                .build();
 
        return openaiService.completions().create(completions);
    }
}
 
// 请求体类
class CompletionRequest {
    private String model;
    private String prompt;
    private Integer maxTokens;
    private Double temperature;
 
    // getter和setter方法
}

这个代码示例展示了如何在Spring Boot应用程序中创建一个REST控制器，它接收一个包含提示和模型信息的CompletionRequest对象，并使用OpenAI的API生成文本。这个控制器方法使用OpenAI的服务来发送完成请求并返回响应。
