在继承HibernateDaoSupport 后怎么查询指定字段

int name() {
Query q=super.getSession().createQuery("update TbUser set age=? where username=?");
q.setInteger(0,18);
q.setString(1,"YourSister");
int i=q.executeUpdate();
return i;
}

List my_findData() {
String hql = "select testa.id,testa.title from testa left join testb on testa.id=testb.id";
List list1 = super.getSession().createQuery(hql).list();
List list2 = new ArrayList();
for(int i=0;i<list1.size();i++){
Tblogin test = new Tblogin();
Object[] o=(Object[])list1.get(i);
int id=Integer.parseInt(o[0].toString());
test.setLoginId(id);
list2.add(test);
}
return list2;
}
