refactor(service): Service 层重构 - 接口与实现分离
重构以下服务类为接口 + 实现类结构，符合三层架构规范： - CourseCollectionService → CourseCollectionService + CourseCollectionServiceImpl - CourseLessonService → CourseLessonService + CourseLessonServiceImpl - ResourceLibraryService → ResourceLibraryService + ResourceLibraryServiceImpl - ThemeService → ThemeService + ThemeServiceImpl 变更详情: - 接口继承 IService<Entity>，定义业务方法签名 - 实现类继承 ServiceImpl 并实现对应接口，添加 @Override 注解 - CourseCollectionServiceImpl 注入 CourseLessonService 接口依赖 - FileStorageService 保持原结构（纯工具类无需拆分） 验证: - mvn compile -DskipTests 编译通过 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# 开发日志 - 2026-03-19
|
||||||
|
|
||||||
|
## Service 层重构
|
||||||
|
|
||||||
|
### 背景
|
||||||
|
|
||||||
|
根据项目统一开发规范要求，Service 层应采用 **接口 + 实现类** 的结构：
|
||||||
|
|
||||||
|
```
|
||||||
|
service/
|
||||||
|
├── XxxService.java ← 接口，继承 IService<Entity>
|
||||||
|
└── impl/
|
||||||
|
└── XxxServiceImpl.java ← 实现类，继承 ServiceImpl 并实现接口
|
||||||
|
```
|
||||||
|
|
||||||
|
### 重构内容
|
||||||
|
|
||||||
|
将以下 5 个服务类从实现类拆分为接口 + 实现类结构：
|
||||||
|
|
||||||
|
| 服务类 | 接口文件 | 实现类文件 | 状态 |
|
||||||
|
|--------|---------|-----------|------|
|
||||||
|
| `ThemeService` | `service/ThemeService.java` | `service/impl/ThemeServiceImpl.java` | ✅ |
|
||||||
|
| `ResourceLibraryService` | `service/ResourceLibraryService.java` | `service/impl/ResourceLibraryServiceImpl.java` | ✅ |
|
||||||
|
| `CourseLessonService` | `service/CourseLessonService.java` | `service/impl/CourseLessonServiceImpl.java` | ✅ |
|
||||||
|
| `CourseCollectionService` | `service/CourseCollectionService.java` | `service/impl/CourseCollectionServiceImpl.java` | ✅ |
|
||||||
|
| `FileStorageService` | 无需拆分（纯工具类） | 保持原结构 | ✅ |
|
||||||
|
|
||||||
|
### 重构详情
|
||||||
|
|
||||||
|
#### 1. ThemeService
|
||||||
|
- **接口方法**：`findAll()`, `findById()`, `create()`, `update()`, `delete()`, `reorder()`
|
||||||
|
- **实现类**：`ThemeServiceImpl` 继承 `ServiceImpl<ThemeMapper, Theme>` 并实现 `ThemeService` 接口
|
||||||
|
|
||||||
|
#### 2. ResourceLibraryService
|
||||||
|
- **接口方法**：`findAllLibraries()`, `findLibraryById()`, `createLibrary()`, `updateLibrary()`, `deleteLibrary()`, `findAllItems()`, `findItemById()`, `createItem()`, `updateItem()`, `deleteItem()`, `batchDeleteItems()`, `getStats()`
|
||||||
|
- **实现类**：`ResourceLibraryServiceImpl` 继承 `ServiceImpl<ResourceLibraryMapper, ResourceLibrary>` 并实现 `ResourceLibraryService` 接口
|
||||||
|
|
||||||
|
#### 3. CourseLessonService
|
||||||
|
- **接口方法**：`findByCourseId()`, `findById()`, `findByType()`, `create()`, `update()`, `delete()`, `reorder()`, `findSteps()`, `createStep()`, `updateStep()`, `deleteStep()`, `reorderSteps()`, `findCourseLessonsForTeacher()`
|
||||||
|
- **实现类**：`CourseLessonServiceImpl` 继承 `ServiceImpl<CourseLessonMapper, CourseLesson>` 并实现 `CourseLessonService` 接口
|
||||||
|
|
||||||
|
#### 4. CourseCollectionService
|
||||||
|
- **接口方法**：`findTenantCollections()`, `getCollectionDetail()`, `pageCollections()`, `getPackagesByCollection()`, `createCollection()`, `setCollectionPackages()`, `updateCollection()`, `deleteCollection()`, `publishCollection()`, `archiveCollection()`, `republishCollection()`, `withdrawCollection()`, `submitCollection()`, `rejectCollection()`, `renewTenantCollection()`
|
||||||
|
- **实现类**：`CourseCollectionServiceImpl` 继承 `ServiceImpl<CourseCollectionMapper, CourseCollection>` 并实现 `CourseCollectionService` 接口
|
||||||
|
- **依赖注入**：注入 `CourseLessonService` 用于查询课程环节
|
||||||
|
|
||||||
|
### 验证结果
|
||||||
|
|
||||||
|
```bash
|
||||||
|
export JAVA_HOME="/f/Java/jdk-17"
|
||||||
|
mvn compile -DskipTests
|
||||||
|
```
|
||||||
|
|
||||||
|
**编译结果**：✅ BUILD SUCCESS
|
||||||
|
|
||||||
|
### 影响范围
|
||||||
|
|
||||||
|
- Controller 层引用保持不变（Spring 自动注入接口实现）
|
||||||
|
- 其他服务层调用保持不变
|
||||||
|
- 无数据库变更
|
||||||
|
- 无 API 变更
|
||||||
|
|
||||||
|
### 备注
|
||||||
|
|
||||||
|
- `FileStorageService` 是纯工具类服务，不涉及数据库操作，无需继承 `IService`，保持当前结构即可
