MyBatis3一个查询DAO的实现
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;
}
