Mybatis RowBounds 限制查询条数的实现代码

private final static int rowLimit = 1000; 
//限制查询条数 
private final static RowBounds QUERY_LIMIT=new RowBounds(0,rowLimit); 
public List<T> select(String sqlID, T t) throws DBException, 
RecordNotFoundException { 
List<T> ret; 
try { 
if ("".equals(sqlID) || (null == sqlID)) { 
ret = getSqlSession().selectList(t.getMapperName() + SELECT, t,QUERY_LIMIT); 
} else { 
ret = getSqlSession().selectList(t.getMapperName() + MAPPER + sqlID, 
t,QUERY_LIMIT); 
} 
} catch (Exception e) { 
LOGGER.error(e.getMessage(), e); 
LOGGER.debug(t.toString()); 
throw new DBException(e); 
} 
if (ret == null && checkNull) { 
throw new RecordNotFoundException(t.getTableName()); 
} 
return ret; 
}
