UiPath2025笔记第十节：利用java反射编写智能体

一、主体思想

将操作方法传递给DeepSeek模型，Ai通过用户的语境识别出要做出的动作，并给出方法。

二、AiUtil工具类

public class AiUtil {public static String getAiResponse(String input) throws JSONException, IOException {OkHttpClient client = new OkHttpClient();// 构建JSON对象JSONObject requestBody = new JSONObject();requestBody.put("model", "deepseek-v3.1-250821");JSONArray messages = new JSONArray();JSONObject systemMsg = new JSONObject();systemMsg.put("role", "system");systemMsg.put("content", "你现在是一个智能体的ai，现在此智能体目前有三个功能台添加，删除，修改，查询用户，分别为add,delete,update,select三个函数。" +"当用户和你对话时，你需根据语境判断出操作方法，以json格式输出，包括回答内容content，操作方法method");messages.put(systemMsg);JSONObject userMsg = new JSONObject();userMsg.put("role", "user");userMsg.put("content", input);messages.put(userMsg);requestBody.put("messages", messages);RequestBody body = RequestBody.create(requestBody.toString(),MediaType.parse("application/json"));Request request = new Request.Builder().url("https://qianfan.baidubce.com/v2/chat/completions").post(body).addHeader("Authorization", "Bearer ").addHeader("Content-Type", "application/json").build();Response response = client.newCall(request).execute();String responseBody = response.body().string();// 解析响应，只提取内容JSONObject jsonResponse = new JSONObject(responseBody);JSONArray choices = jsonResponse.getJSONArray("choices");JSONObject firstChoice = choices.getJSONObject(0);JSONObject message = firstChoice.getJSONObject("message");return message.getString("content");}
}

三、Ai要操作的方法

public class Utils {public Utils() {}public static void add(){System.out.println("添加用户成功");}public static void delete(){System.out.println("删除用户成功");}public static void update(){System.out.println("更新用户成功");}public static void select(){System.out.println("查找用户成功");}}

四、测试

public class Test01 {@Testpublic void test1() throws IOException, ClassNotFoundException, NoSuchMethodException, InstantiationException, IllegalAccessException, InvocationTargetException {String aiResponse = AiUtil.getAiResponse("我忘了我的用户信息了");System.out.println(aiResponse);JSONObject jsonObject = new JSONObject(aiResponse);String methodName = jsonObject.getString("method"); // 得到"add"System.out.println(methodName);Class<?> aClass = Class.forName("com.zy.Utils");Object instance = aClass.newInstance();Method method = aClass.getMethod(methodName);method.invoke(instance);}
}
