+
+## 🔧 **代码生成规范**
+
+### **1. API 接口生成**
+
+#### **基本结构**
+```dart
+// {Tag} API 接口定义
+// 基于 Swagger API 文档: {swagger_url}
+// 由 xy_swagger_generator by max 生成
+// Copyright (C) 2025 YuanXuan. All rights reserved.
+
+import 'package:dio/dio.dart';
+import 'package:retrofit/retrofit.dart';
+import 'package:learning_officer_oa/common/models/common/base_result.dart';
+
+// 按需导入分页类型
+import 'package:learning_officer_oa/common/models/common/base_page_result.dart';
+
+part '{tag_name}_api.g.dart';
+
+/// {Tag} API 接口
+/// 负责处理 {Tag} 相关的接口
+@RestApi(parser: Parser.JsonSerializable)
+abstract class {Tag}Api {
+  factory {Tag}Api(Dio dio, {String? baseUrl}) = _{Tag}Api;
+}
+```
+
+#### **方法生成规则**
+```dart
+/// {summary}
+@{HTTP_METHOD}('{path}')
+Future<{ReturnType}> {methodName}(
+  // 路径参数
+  @Path('{param}') {Type} param,
+  // 查询参数
+  @Query('{param}') {Type}? param,
+  // 请求体（仅当 swagger 中明确定义时）
+  @Body() {Type} request
+);
+```
+
+### **2. 返回类型规范**
+
+#### **类型提取优先级**
+1. **从 responses.200.content.application/json.schema 提取**
+2. **从 responses.200.content.text/plain.schema 提取**
+3. **特殊处理**: 健康检查接口返回 `BaseResult<void>`
+4. **默认**: `BaseResult<Map<String, dynamic>>`
+
+#### **分页类型判断**
+```dart
+// 当返回类型包含分页结构时使用 BasePageResult
+BasePageResult<{ItemType}>
+
+// 判断依据:
+// 1. schema 中包含 pageIndex, pageSize, totalCount 等字段
+// 2. 查询参数中包含分页参数 (page, size, limit 等)
+```
+
+### **3. 请求体生成规范**
+
+#### **添加 @Body() 的条件**
+```dart
+// 仅在以下情况添加 @Body() 参数:
+// 1. requestBody 在 swagger 中明确定义
+// 2. parameters 中存在 in: "body" 的参数
+// 3. 其他情况一律不添加
+```
+
+#### **请求体类型提取**
+```dart
+// 优先级:
+// 1. requestBody.content.application/json.schema
+// 2. requestBody.content.text/plain.schema
+// 3. 默认: Map<String, dynamic>
+```
+
+---
+
+## 📝 **数据模型生成规范**
+
+### **1. 模型类结构**
+
+#### **基本模板**
+```dart
+// {schemaName} 模型定义
+// 基于 Swagger API 文档: {swagger_url}
+// 由 xy_swagger_generator by max 生成
+// Copyright (C) 2025 YuanXuan. All rights reserved.
+
+import 'package:json_annotation/json_annotation.dart';
+import 'index.dart';
+
+part '{schema_name}.g.dart';
+
+@JsonSerializable(checked: true, includeIfNull: false)
+class {SchemaName} {
+  // 属性定义
+
+  const {SchemaName}({
+    // 构造函数参数
+  });
+
+  factory {SchemaName}.fromJson(Map<String, dynamic> json) =>
+      _${SchemaName}FromJson(json);
+
+  Map<String, dynamic> toJson() => _${SchemaName}ToJson(this);
+}
+```
+
+### **2. 属性生成规则**
+
+#### **可空性判断**
+```dart
+// 严格按照 OpenAPI 规范:
+// 1. 有 "nullable": true -> 可空类型 (Type?)
+// 2. 没有 "nullable": true -> 非空类型 (Type)
+// 3. 忽略 required 字段，只看 nullable
+
+final String name;        // 非空
+final String? nickname;   // 可空 (nullable: true)
+```
+
+#### **类型映射**
+```dart
+// OpenAPI -> Dart 类型映射
+"string"    -> String
+"integer"   -> int
+"number"    -> double
+"boolean"   -> bool
+"array"     -> List<T>
+"object"    -> Map<String, dynamic> 或具体类型
+"$ref"      -> 引用的具体类型
+```
+
+#### **构造函数规则**
+```dart
+const {ClassName}({
+  required this.nonNullableField,  // 非空字段必须 required
+  this.nullableField,              // 可空字段不需要 required
+});
+```
+
+### **3. 导入管理**
+
+#### **按需导入原则**
+```dart
+// 只导入实际使用的类型
+// 分页相关
+import 'package:learning_officer_oa/common/models/common/base_page_result.dart';
+
+// 基础响应
+import 'package:learning_officer_oa/common/models/common/base_result.dart';
+
+// 模型类型
+import '../../api_models/{model_name}.dart';
+```
+
+---
+
+## 🚫 **禁止事项**
+
+### **1. 硬编码推断**
+```dart
+// ❌ 禁止基于路径关键词推断类型
+if (path.contains('login')) return 'UserLoginResult';
+
+// ❌ 禁止基于 tag 推断类型
+if (tag.contains('task')) return 'TaskInfoResult';
+
+// ❌ 禁止基于操作推断请求体
+if (method == 'POST') addBody();
+```
+
+### **2. 不存在的类型**
+```dart
+// ❌ 禁止生成 swagger 中不存在的类型
+Future<BaseResult<TaskInfoResult>>  // TaskInfoResult 不存在
+
+// ✅ 使用通用类型或实际存在的类型
+Future<BaseResult<Map<String, dynamic>>>
+Future<BaseResult<ActualExistingType>>
+```
+
+### **3. 主观判断**
+```dart
+// ❌ 禁止主观添加参数
+@Body() Map<String, dynamic> request  // swagger 中没有定义
+
+// ❌ 禁止主观修改类型
+List<dynamic> -> List<SpecificType>   // 没有明确的 items schema
+```
+
+---
+
+## ✅ **质量保证**
+
+### **1. 生成前检查**
+- **验证 swagger.json 格式正确性**
+- **检查所有 $ref 引用完整性**
+- **确认 components/schemas 定义完整**
+
+### **2. 生成后验证**
+- **所有生成的类型在 swagger 中都有定义**
+- **没有硬编码的类型映射**
+- **导入语句按需生成**
+- **代码通过 dart analyze 检查**
+
+### **3. 错误处理**
+```dart
+// 当 swagger 定义不完整时的处理策略:
+// 1. 记录警告日志
+// 2. 使用安全的默认类型
+// 3. 提示完善 swagger 文档
+// 4. 不进行主观推断
+```
+
+---
+
+## 📞 **沟通机制**
+
+### **文档问题反馈**
+1. **发现 swagger 定义缺失** -> 联系后端完善
+2. **类型定义不明确** -> 要求明确 schema
+3. **响应结构不一致** -> 统一响应格式
+4. **参数定义缺失** -> 补充参数说明
+
+### **版本管理**
+- **swagger.json 版本控制**
+- **生成代码版本标记**
+- **变更日志记录**
+- **向后兼容性检查**
+
+---
+
+## 🛠️ **工具配置规范**
+
+### **1. 生成器配置**
+```yaml
+# pubspec.yaml
+dependencies:
+  dio: ^5.0.0
+  retrofit: ^4.0.0
+  json_annotation: ^4.8.0
+
+dev_dependencies:
+  build_runner: ^2.3.0
+  retrofit_generator: ^8.0.0
+  json_serializable: ^6.6.0
+```
+
+### **2. 构建配置**
+```yaml
+# build.yaml
+targets:
+  $default:
+    builders:
+      json_serializable:
+        options:
+          checked: true
+          include_if_null: false
+          explicit_to_json: true
+```
+
+### **3. 分析配置**
+```yaml
+# analysis_options.yaml
+analyzer:
+  strong-mode:
+    implicit-casts: false
+    implicit-dynamic: false
+
+linter:
+  rules:
+    - prefer_const_constructors
+    - prefer_final_fields
+    - avoid_dynamic_calls
+```
+
+---
+
+## 📚 **最佳实践示例**
+
+### **1. 标准 API 接口**
+```dart
+/// 用户登录
+@POST('/api/v1/Login/userLogin')
+Future<BaseResult<UserLoginResult>> userLogin(
+  @Body() LoginRequest request
+);
+
+/// 获取用户列表（分页）
+@GET('/api/v1/User/GetUserList')
+Future<BasePageResult<UserResult>> getUserList(
+  @Query('page') int page,
+  @Query('size') int size,
+  @Query('keyword') String? keyword
+);
+
+/// 健康检查
+@GET('/health')
+Future<BaseResult<void>> healthCheck();
+
+/// 无明确 schema 的接口
+@POST('/api/v1/Action/DoSomething')
+Future<BaseResult<Map<String, dynamic>>> doSomething();
+```
+
+### **2. 标准数据模型**
+```dart
+@JsonSerializable(checked: true, includeIfNull: false)
+class UserResult {
+  /// 用户ID
+  final int id;
+
+  /// 用户名
+  final String username;
+
+  /// 昵称（可空）
+  final String? nickname;
+
+  /// 头像URL（可空）
+  final String? avatarUrl;
+
+  /// 是否激活
+  final bool isActive;
+
+  const UserResult({
+    required this.id,
+    required this.username,
+    this.nickname,
+    this.avatarUrl,
+    required this.isActive,
+  });
+
+  factory UserResult.fromJson(Map<String, dynamic> json) =>
+      _$UserResultFromJson(json);
+
+  Map<String, dynamic> toJson() => _$UserResultToJson(this);
+}
+```
+
+### **3. 参数类生成**
+```dart
+@JsonSerializable(checked: true, includeIfNull: false)
+class GetUserListParameters {
+  final int page;
+  final int size;
+  final String? keyword;
+
+  const GetUserListParameters({
+    required this.page,
+    required this.size,
+    this.keyword,
+  });
+
+  factory GetUserListParameters.fromJson(Map<String, dynamic> json) =>
+      _$GetUserListParametersFromJson(json);
+
+  Map<String, dynamic> toJson() => _$GetUserListParametersToJson(this);
+}
+```

+  
+  ApiGenerator({
+    required this.className,
+    this.generateModels = true,

+- **文件名**: snake_case (`api_generator.dart`)
+
+### 注释规范
+
+```dart
+/// 生成 Retrofit API 代码的生成器
+/// 
+/// 支持多种配置选项，包括：
+/// - 模块化 API 生成
+/// - 基础响应类型
+/// - 分页支持
+/// 
+/// 示例用法：
+/// ```dart
+/// final generator = RetrofitApiGenerator(
+///   className: 'ApiService',
+///   splitByTags: true,
+/// );
+/// ```
+class RetrofitApiGenerator {
+  /// API 服务类名
+  final String className;
+  
+  /// 是否按标签分割 API
+  final bool splitByTags;
+  
+  /// 创建 Retrofit API 生成器
+  /// 
+  /// [className] 生成的 API 服务类名
+  /// [splitByTags] 是否按标签分割成多个 API 类
+  RetrofitApiGenerator({
+    this.className = 'ApiService',
+    this.splitByTags = false,
+  });
+}

+# Augment 代码生成快速参考
+
+## 🚀 **快速开始**
+
+### **生成 API 代码**
+```bash
+# 生成所有代码
+dart run bin/main.dart generate --api --models --split-by-tags
+
+# 只生成 API 接口
+dart run bin/main.dart generate --api --split-by-tags
+
+# 只生成数据模型
+dart run bin/main.dart generate --models
+```
+
+### **项目集成**
+```yaml
+# pubspec.yaml
+dependencies:
+  dio: ^5.0.0
+  retrofit: ^4.0.0
+  json_annotation: ^4.8.0
+
+dev_dependencies:

+  json_serializable: ^6.6.0
+```
+
+```bash
+# 运行代码生成
+dart pub get
+dart pub run build_runner build
+```
+
+---
+
+## 📋 **常见问题解决**
+
+### **Q: 生成的类型不存在怎么办？**
+```dart
+// ❌ 错误：生成了不存在的类型
+Future<BaseResult<TaskInfoResult>> someMethod();
+
+// ✅ 解决：检查 swagger.json 中是否定义了 TaskInfoResult
+// 如果没有定义，联系后端添加 schema 定义
+// 或者使用通用类型：
+Future<BaseResult<Map<String, dynamic>>> someMethod();
+```
+
+### **Q: 接口缺少参数怎么办？**
+```dart
+// ❌ 错误：swagger 中没有定义参数，但生成器添加了
+@POST('/api/v1/SomeAction')
+Future<BaseResult<void>> someAction(
+  @Body() Map<String, dynamic> request  // 不应该存在
+);
+
+// ✅ 解决：检查 swagger.json 中的参数定义
+// 如果确实需要参数，联系后端在 swagger 中添加定义
+```
+
+### **Q: 可空性不正确怎么办？**
+```dart
+// ❌ 错误：字段应该可空但生成为非空
+final String name;  // 但实际可能为 null
+
+// ✅ 解决：检查 swagger.json 中的 nullable 字段
+{
+  "name": {
+    "type": "string",
+    "nullable": true  // 添加这个字段
+  }
+}
+```
+
+### **Q: 分页接口没有使用 BasePageResult？**
+```dart
+// ❌ 错误：分页接口使用了错误的返回类型
+Future<BaseResult<List<UserResult>>> getUserList();
+
+// ✅ 解决：检查接口是否真的是分页接口
+// 确保 swagger 中定义了分页相关的查询参数和响应结构
+Future<BasePageResult<UserResult>> getUserList();
+```
+
+---
+
+## 🔧 **调试技巧**
+
+### **1. 检查 swagger.json**
+```bash
+# 验证 swagger.json 格式
+curl -X POST "https://validator.swagger.io/validator/debug" \
+  -H "Content-Type: application/json" \
+  -d @swagger.json
+```
+
+### **2. 查看生成日志**
+```bash
+# 启用详细日志
+dart run bin/main.dart generate --api --models --verbose
+```
+
+### **3. 手动验证类型**
+```dart
+// 在生成的代码中添加断言验证
+assert(response.data is UserResult);
+assert(response.data?.name != null);
+```
+
+---
+
+## 📝 **代码模板**
+
+### **标准 API 接口模板**
+```dart
+/// {接口描述}
+@{HTTP_METHOD}('{路径}')
+Future<{返回类型}> {方法名}(
+  // 路径参数（如果有）
+  @Path('{参数名}') {类型} 参数名,
+  
+  // 查询参数（如果有）
+  @Query('{参数名}') {类型}? 参数名,
+  
+  // 请求体（仅当 swagger 中明确定义时）
+  @Body() {类型} request
+);
+```
+
+### **标准数据模型模板**
+```dart
+@JsonSerializable(checked: true, includeIfNull: false)
+class {类名} {
+  /// {字段描述}
+  final {类型} {字段名};
+  
+  const {类名}({
+    required this.{非空字段},
+    this.{可空字段},
+  });
+
+  factory {类名}.fromJson(Map<String, dynamic> json) =>
+      _${类名}FromJson(json);
+
+  Map<String, dynamic> toJson() => _${类名}ToJson(this);
+}
+```
+
+---
+
+## ⚡ **性能优化**
+
+### **1. 按需导入**
+```dart
+// ✅ 只导入需要的类型
+import 'package:learning_officer_oa/common/models/common/base_result.dart';
+
+// ❌ 避免导入不需要的类型
+// import 'package:learning_officer_oa/common/models/common/base_page_result.dart';
+```
+
+### **2. 使用 const 构造函数**
+```dart
+// ✅ 使用 const 构造函数
+const UserResult({
+  required this.id,
+  required this.name,
+});
+
+// ❌ 避免非 const 构造函数
+UserResult({
+  required this.id,
+  required this.name,
+});
+```
+
+### **3. 合理的类型选择**
+```dart
+// ✅ 使用具体类型
+Future<BaseResult<UserResult>> getUser();
+
+// ❌ 避免过度使用 dynamic
+Future<BaseResult<dynamic>> getUser();
+```

+  final String baseResultType;
+  final String pageResultType;
+  
+  OptimizedRetrofitGenerator({
+    this.className = 'ApiService',
+    this.generateModularApis = true,
+    this.generateBaseResult = true,
+    this.generatePagination = true,
+    this.generateFileUpload = true,
+    this.baseResultType = 'BaseResult',
+    this.pageResultType = 'BasePageResult',
+  });
+}
+```
+
+#### 特性
