1.數據層使用了SqlSugar 庫類 。
數據層使用了SqlSugar 庫類 ,有興趣的 可以學習 http://www.codeisbug.com/Doc/8/1133,個人覺得比EF 簡單,容易上手,推薦+1。
數據層使用代碼生成,所以考慮得比較多。
1.GetAllList()--獲取全部數據
2.GetAllListByCache()--通過緩存獲取全部數據
3.GetListByCondition(string queryJson)--通過條件獲取數據
4.GetListByPage(PageInfo pageInfo, string queryJson)--通過 條件 和 分頁 信息 獲取數據
5.GetEntity(string keyValue)--通過主鍵 獲取 單條實體
6.DelEntity(string keyValue)--通過主鍵 刪除 單條實體
7.DelListByCondition(string queryJson)--通過條件 刪除 單條實體
8.DelEntityByKeys(int[] keyValues)--通過主鍵 刪除 數據
9.SaveForm(string keyValue, T Entity)--保存數據(新增、修改)
2.動軟代碼
