定时任务管理服务模块
|
||||
=============================================================
|
||||
|
||||
该模块实现了定时任务管理相关的所有业务逻辑。
|
||||
包括任务的分页查询、详情查询、添加、更新、删除、状态设置等功能。
|
||||
|
||||
主要功能：
|
||||
1. 分页查询：支持按任务名称、状态等条件筛选
|
||||
2. 详情查询：根据ID获取任务详细信息
|
||||
3. 任务管理：添加、更新、删除（支持批量）
|
||||
4. 状态管理：启用、暂停、恢复任务
|
||||
5. 立即执行：手动触发任务执行
|
||||
6. 调度器同步：自动同步任务状态到调度器
