MyBatis3一个查询DAO的实现
/** * 订单查询(用于订单列表展示用) */ public List<Ord> queryOrd(String ordno, String custno, int startRow, int rowSize, Ord.St... stArr) { Map<String, Object> map = params4queryOrd(ordno, custno, stArr); return getSqlSession().selectList(sqlmapNamespace + "." + "queryOrd", map, new RowBounds(startRow, rowSize)); } public int countOrd(String ordno, String custno, Ord.St... stArr) { Map<String, Object> map = params4queryOrd(ordno, custno, stArr); return getSqlSession().selectOne(sqlmapNamespace + "." + "countOrd", map); } private Map<String, Object> params4queryOrd(String ordno, String custno, Ord.St... stArr) { Map<String, Object> map = new HashMap<>(3); if (ordno != null) map.put("ordno", ordno); if (custno != null) map.put("custno", custno); if (stArr != null && stArr.length > 0) { int[] arr = new int[stArr.length]; for (int i = 0; i < stArr.length; i++) { arr[i] = stArr[i].key; } map.put("stArr", arr); } return map; }
