|
|||
|
|
|
|||
|
|
---
|
|||
|
|
|
|||
|
|
## 四、更新的 Service 接口和实现
|
|||
|
|
|
|||
|
|
### TeacherDashboardService
|
|||
|
|
**更新内容**: 将返回类型从 `Map<String, Object>` 改为具体 DTO
|
|||
|
|
|
|||
|
|
| 方法 | 原返回类型 | 新返回类型 |
|
|||
|
|
|------|----------|----------|
|
|||
|
|
| `getDashboard` | `Map<String, Object>` | `TeacherDashboardResponse` |
|
|||
|
|
| `getTodayLessons` | `List<Map<String, Object>>` | `List<LessonSimpleResponse>` |

|||
|
|
|
|||
|
|

|
|||
|
|
|
|||
|
|
## 五、已完善的 Mapper 层
|
|||
|
|
|
|||
|
|
所有 Mapper 接口已继承 `BaseMapper<T>`，具备以下基础方法：
|
|||
|
|
|
|||
|
|
| Mapper 名称 | 实体类型 | 支持的方法 |
|
|||
|
|
|-----------|---------|-----------|
|
|||
|
|
| `TeacherMapper` | `Teacher` | 增删改查、分页、条件查询 |
|
|||
|
|
| `StudentMapper` | `Student` | 增删改查、分页、条件查询 |
|
|||
|
|
| `ClazzMapper` | `Clazz` | 增删改查、分页、条件查询 |
|
|||
|
|
| `CourseMapper` | `Course` | 增删改查、分页、条件查询 |
|
|||
|
|
| `LessonMapper` | `Lesson` | 增删改查、分页、条件查询 |
|
|||
|
|
| `TaskMapper` | `Task` | 增删改查、分页、条件查询 |
|
|||
|
|
| `TaskCompletionMapper` | `TaskCompletion` | 增删改查、分页、条件查询 |
|
|||
|
|
| `GrowthRecordMapper` | `GrowthRecord` | 增删改查、分页、条件查询 |
|
|||
|
|
| `NotificationMapper` | `Notification` | 增删改查、分页、条件查询 |
|
|||
|
|
| `ClassTeacherMapper` | `ClassTeacher` | 增删改查、分页、条件查询 |
|
|||
|
|
| `LessonFeedbackMapper` | `LessonFeedback` | 增删改查、分页、条件查询 |
|
|||
|
|
| `StudentRecordMapper` | `StudentRecord` | 增删改查、分页、条件查询 |
|
|||
|
|
| `ResourceLibraryMapper` | `ResourceLibrary` | 增删改查、分页、条件查询 |
|
|||
|
|
| `ResourceItemMapper` | `ResourceItem` | 增删改查、分页、条件查询 |
|
|||
|
|
| `OperationLogMapper` | `OperationLog` | 增删改查、分页、条件查询 |
|
|||
|
|
| `AdminStatsMapper` | - | 统计查询 |
|
|||
|
|
| `TenantMapper` | `Tenant` | 增删改查、分页、条件查询 |
|
|||
|
|
| `CourseLessonMapper` | `CourseLesson` | 增删改查、分页、条件查询 |
|
|||
|
|
|
|||
|

|
|||
|
|
|
|||
|
|
## 六、使用 DTO 替代 Map 的优势
|
|||
|
|
|
|||
|
|
### 之前的代码（使用 Map）
|
|||
|
|
```java
|
|||
|
|
@GetMapping("/recommend")
|
|||
|
|
public Result<List<Map<String, Object>>> getRecommendedCourses() {
|
|||
|
|
List<Map<String, Object>> courses = service.getCourses();
|
|||
|
|
// 前端需要猜测字段含义
|
|||
|
|
return Result.success(courses);
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 改进后的代码（使用 DTO）
|
|||
|
|
```java
|
|||
|
|
@GetMapping("/recommend")
|
|||
|
|
public Result<List<RecommendedCourseResponse>> getRecommendedCourses() {
|
|||
|
|
return Result.success(service.getCourses());
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### 优势
|
|||
|
|
1. **类型安全**: 编译时检查字段类型
|
|||
|
|
2. **API 文档**: 自动生成 Swagger 文档，字段含义清晰
|
|||
|
|
3. **前端提示**: TypeScript 类型定义自动生成
|
|||
|
|
4. **重构友好**: IDE 可以安全重构字段名
|
|||
|
|
5. **代码可读性**: 一看就知道返回的是什么数据
|
|||
|
|
|
|||

|
|||
|
|
|
|||
|
|
## 七、接口完成率
|
|||
|
|
|
|||
|
|
### 旧后端 (NestJS) vs 新后端 (Spring Boot)
|
|||
|
|
|
|||
|
|
| 模块 | 旧后端接口数 | 新后端接口数 | 完成率 |
|
|||
|
|
|------|------------|------------|--------|
|
|||
|
|
| 教师端 | 37 | 40 | 100% |
|
|||
|
|
| 学校端 | 58 | 65 | 100% |
|
|||
|
|
| 家长端 | 14 | 14 | 100% |
|
|||
|
|
| 管理员端 | 39 | 39 | 100% |
|
|||
|
|
| 报告功能 | 4 | 5 | 100% |
|
|||
|
|
| **总计** | **152** | **163** | **100%** |
|
|||
|
|
|
|||
|
|
**备注**: 新后端接口数多于旧后端，因为补充了一些实用的增强接口。
|
|||

|
|||
|
|
|
|||
|
|
### 完成内容
|
|||
|
|
1. ✅ 实现剩余 4 个报告接口（`/reports/overview`、`/reports/teachers`、`/reports/courses`、`/reports/students`）
|
|||
|
|
2. ✅ 完善 Service 层代码，所有方法都有完整实现
|
|||
|
|
3. ✅ 接口返回体使用 DTO 替代 Map，类型安全、文档清晰
|
|||
|
|
|
|||
|
|
### 代码质量提升
|
|||
|
|
- 所有接口返回类型都是具体的 DTO 类
|
|||
|
|
- 所有 DTO 都有 `@Schema` 注解，生成完整的 API 文档
|
|||
|
|
- 所有 Service 方法都有清晰的注释
|
|||
|
|
- 所有 Controller 方法都有 `@Operation` 注解
|
|||
|
|
|
|||
|
|
### 端到端测试就绪
|
|||
|
|
- 所有接口已实现
|
|||
|
|
- 所有 Service 方法已实现
|
|||
|
|
- 所有 Mapper 已继承 BaseMapper
|
|||
|
|
