- 概要
- 重构并扩展公告相关模型、DTO、服务,新增公告类型、图片与时间字段,调整缓存与查询处理。
- 新增枚举 AnnouncementTypeEnum。
- 主要改动(简要)
- Yi.Framework.AiHub.Application.Contracts/Dtos/Announcement/AnnouncementLogDto.cs
- 新增 ImageUrl、StartTime、EndTime、Type 字段,移除 Date 字段,Title 不再默认空串。
- Yi.Framework.AiHub.Domain/Entities
- 重命名 AnnouncementLogAggregateRoot -> AnnouncementAggregateRoot
- 表名由 Ai_AnnouncementLog 改为 Ai_Announcement(SugarTable 标注)
- 新增 ImageUrl、StartTime、EndTime、Type、Remark 字段(Remark 已存在,保持)
- Yi.Framework.AiHub.Domain.Shared/Enums/AnnouncementTypeEnum.cs
- 新增枚举文件(Activity=1, System=2)
- Yi.Framework.AiHub.Application.Contracts/IServices/IAnnouncementService.cs
- GetAsync 返回类型由 AnnouncementOutput 改为 List<AnnouncementLogDto>
- Yi.Framework.AiHub.Application/Services/AnnouncementService.cs
- 使用 Mapster 进行 DTO 映射
- 查询按 StartTime 降序,返回 List<AnnouncementLogDto>,缓存结构简化
- Yi.Abp.Web/YiAbpWebModule.cs
- 改为初始化 AnnouncementAggregateRoot 的表(Ai_Announcement)
- Yi.Ai.Vue3/types/import_meta.d.ts
- 移除 VITE_BUILD_COMPRESS 环境变量声明
- 重要注意/兼容性提示
- 接口变更:IAnnouncementService.GetAsync 返回类型已改变,调用方需同步更新(之前返回 AnnouncementOutput 的代码需调整)。
- 数据库表变更:表名从 Ai_AnnouncementLog -> Ai_Announcement,若需保留历史数据,请在部署前做好数据迁移(重命名表或迁移数据到新表结构),或使用 CodeFirst 初始化新表(当前代码在启动时会 InitTables<AnnouncementAggregateRoot>())。
- 新增 Mapster 适配(确保项目有 Mapster 依赖)。
- 前端类型声明移除环境变量后,前端构建/运行脚本若依赖 VITE_BUILD_COMPRESS 需同步调整。
- 若有缓存结构(AnnouncementCacheDto)或序列化相关约定变更,确认兼容性。
- 建议操作
- 更新所有使用 IAnnouncementService 的代码(API 层/前端适配返回结构)。
- 在非生产环境先执行数据迁移验证(保留旧表数据或写迁移脚本)。
- 确认 Mapster 包已安装并编译通过。
- 前端项目检查并同步 import_meta.d.ts 变更。
