//DAO中根据用户名和密码查询用户的方法(HQL查询)
@Override
public Employee findByUsernameAndPassword(Employee employee) {
String hql="from Employee where username = :username and password = :password";
List<?> list=this.getHibernateTemplate().find(hql, employee.getUsername(),employee.getPassword());
if (list.size()>0) {
