1.目录结构

2.OpenAiProperties.java 新增apiUrl

package com.sunxiansheng.openai.config.properties;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;/*** Description: OpenAI配置属性类** @Author sun* @Create 2024/12/14 11:44* @Version 1.0*/
@Data
@ConfigurationProperties(prefix = "openai")
public class OpenAiProperties {/*** OpenAI API Key*/private String apiKey;/*** OpenAI API URL 有默认值*/private String apiUrl = "https://api.openai.com/v1/chat/completions";
}

3.OpenAIAutoConfiguration.java

package com.sunxiansheng.openai.config;import com.sunxiansheng.openai.client.OpenAiClient;
import com.sunxiansheng.openai.config.properties.OpenAiProperties;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;/*** Description: OpenAI自动配置类** @Author sun* @Create 2024/12/14 11:39* @Version 1.0*/
@Configuration
@EnableConfigurationProperties({OpenAiProperties.class}) // 启用配置类
public class OpenAIAutoConfiguration {/*** 创建 OpenAiClient** @return*/@Bean@ConditionalOnMissingBeanpublic OpenAiClient openAiClient() {return new OpenAiClient();}
}

4.OpenAiClient.java 使用gson重构

package com.sunxiansheng.openai.client;import com.google.gson.JsonArray;
import com.google.gson.JsonObject;
import com.google.gson.JsonParser;
import com.sunxiansheng.openai.config.properties.OpenAiProperties;

import java.util.logging.Logger;/*** Description: OpenAI 客户端类** @Author sun* @Create 2024/12/14 11:56* @Version 1.1*/
public class OpenAiClient {@Resourceprivate OpenAiProperties openAiProperties;private static final OkHttpClient CLIENT = new OkHttpClient.Builder().connectTimeout(120, TimeUnit.SECONDS).readTimeout(120, TimeUnit.SECONDS).writeTimeout(120, TimeUnit.SECONDS).build();private static final Logger LOGGER = Logger.getLogger(OpenAiClient.class.getName());/*** 向 AI 提问通用方法** @param model        使用的 AI 模型，如 "gpt-4o"* @param prompt       提示内容* @param base64Encode 是否对内容进行 Base64 编码* @return AI 的响应内容*/public String askAI(String model, String prompt, boolean base64Encode) {try {// 处理 Base64 编码String encodedPrompt = base64Encode ? encodeBase64(prompt) : prompt;// 构造请求体RequestBody body = RequestBody.create(createJsonRequest(model, encodedPrompt), MediaType.get("application/json; charset=utf-8"));// 构建请求Request request = new Request.Builder().url(openAiProperties.getApiUrl()).header("Authorization", "Bearer " + openAiProperties.getApiKey()).header("Content-Type", "application/json").post(body).build();// 发送请求并获取响应try (Response response = CLIENT.newCall(request).execute()) {if (!response.isSuccessful()) {throw new IOException("Unexpected response: " + response);}// 解析 JSON 响应return parseResponse(response.body().string());}} catch (IOException e) {LOGGER.log(Level.SEVERE, "Error occurred during API request: " + e.getMessage(), e);throw new RuntimeException("API request failed", e);}}/*** 对输入内容进行 Base64 编码** @param prompt 输入内容* @return 编码后的字符串*/private String encodeBase64(String prompt) {return Base64.getEncoder().encodeToString(prompt.getBytes(StandardCharsets.UTF_8));}/*** 构建请求的 JSON 数据** @param model         使用的 AI 模型* @param encodedPrompt 编码后的输入内容* @return 构建好的 JSON 字符串*/private String createJsonRequest(String model, String encodedPrompt) {JsonObject jsonRequest = new JsonObject();jsonRequest.addProperty("model", model);JsonArray messages = new JsonArray();// 添加 system 信息JsonObject systemMessage = new JsonObject();systemMessage.addProperty("role", "system");systemMessage.addProperty("content", "请根据以下内容提供问题的解决方案。使用中文回答，不要使用markdown语法和特殊符号**之类的，注意，内容可能经过 Base64 编码。");messages.add(systemMessage);// 添加 user 信息JsonObject userMessage = new JsonObject();userMessage.addProperty("role", "user");userMessage.addProperty("content", encodedPrompt);messages.add(userMessage);jsonRequest.add("messages", messages);return jsonRequest.toString();}/*** 解析 API 响应内容** @param responseBody 响应的 JSON 内容* @return 解析后的结果*/private String parseResponse(String responseBody) {JsonObject jsonObject = JsonParser.parseString(responseBody).getAsJsonObject();JsonArray choices = jsonObject.getAsJsonArray("choices");if (choices != null && choices.size() > 0) {JsonObject choice = choices.get(0).getAsJsonObject();JsonObject message = choice.getAsJsonObject("message");return message.get("content").getAsString();}throw new RuntimeException("Invalid response: No choices found.");}
}

1.目录结构

2.application.yml 新增api-url

openai:api-key: guest # 必填，OpenAI API Keyapi-url: https://api.openai.com/v1/chat/completions # 可选，有默认值，为了防止以后 URL 变化

3.OpenAiController.java

package com.sunxiansheng.openai.controller;import com.sunxiansheng.openai.client.OpenAiClient;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import javax.annotation.Resource;/*** Description: OpenAI 控制器类** @Author sun* @Create 2024/12/14 12:27* @Version 1.0*/
@RestController
public class OpenAiController {@Resourceprivate OpenAiClient openAiClient;@RequestMapping("/ask")public String ask(String question) {String res = openAiClient.askAI("gpt-4o", question, false);return "AI回答：" + res;}
}

4.OpenAiApplication.java

package com.sunxiansheng.openai;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** Description: OpenAI启动类** @Author sun* @Create 2024/12/14 12:23* @Version 1.0*/
@SpringBootApplication
public class OpenAiApplication {public static void main(String[] args) {SpringApplication.run(OpenAiApplication.class, args);}
}
