實現商鋪管理

實現商店列表

實現分頁查詢店鋪，通過條件組合，來篩選出條件範圍內的店鋪列表

分頁查詢中使用LIMIT

第一個參數指定第一個返回記錄行的偏移量，第二個參數指定返回記錄行的最大數目

 1 /**
 2      * 分頁查詢店鋪,可輸入的條件有：店鋪名(模糊)，店鋪狀態，店鋪類別，區域id，owner
 3      * @param shopCondition
 4      * @param rowIndex 從第幾行開始取數據
 5      * @param pageSize 表示返回多少行數據
 6      * @param 標簽的作用 取參數的時候需要唯一的標識
 
 7      * @return
 8      */
 9     List<Shop> queryShopList(@Param("shopCondition")Shop shopCondition,
10             @Param("rowIndex") int rowIndex,@Param("pageSize") int pageSize);
11     /**
12      * 返回queryShopList總數
13      * @param shopCondition
14      * @return
15      */
16     int
 
 queryShopCount(@Param("shopCondition")Shop shopCondition);

SQL

分頁查詢店鋪信息：可輸入的條件有：店鋪名（模糊查詢），店鋪狀態，店鋪類別，區域Id,owner

使用動態SQL來查
