為什么賬號(hào)密碼跟數(shù)據(jù)庫的數(shù)據(jù)都一樣但是顯示密碼錯(cuò)誤，控制臺(tái)沒有報(bào)錯(cuò)誤，也生成了sql語句

dao層的主要代碼：

public class EmployeeDaoImpl implements EmployeeDao {

private SessionFactory sessionFactory;

public void setSessionFactory(SessionFactory sessionFactory) {

this.sessionFactory = sessionFactory;

}

@Override

public Employee findByUsAndPw(Employee employee) {

// TODO Auto-generated method stub

String hql="from Employee where username=? and password=?";

Session session=sessionFactory.getCurrentSession();

Transaction tx=session.beginTransaction();

Query query=session.createQuery(hql);

query.setParameter(0, employee.getUsername());

query.setParameter(1, employee.getPassword());

List <Employee> list=query.list();

/*

* 這里存在Hibernate版本的問題 ? 抽時(shí)間弄

*?

*/

tx.commit();

if(list.size()>0){

return list.get(0);

}

return null;

}

}
