Struts1.2+Spring2.5+Hibernate3.2框架搭建（十）
IUsesDAO.java 内容如下：
package com.zlk.dao;
?
import com.zlk.pojo.Users;
?
public interface IUsersDao {
??? /**
??? ?* 检测用户名是否存在
??? ?*/
??? public Users getUserByName(String username);
???
??? /**
??? ?* 判断用户名和密码是否存在
??? ?*/
??? public Users getUser(String username,String password);
?
??? /**
??? ?* 添加用户
??? ?*/
??? public boolean saveUser(Users users);
}
?
UsersDAOImpl.java 内容如下：
package com.zlk.dao.impl;
?
import java.util.List;
?
import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
?
import com.zlk.dao.IUsersDao;
import com.zlk.pojo.Users;
?
public class UsersDaoImpl extends HibernateDaoSupport implements IUsersDao {
?
??? public Users getUserByName(String username) {
?????? // TODO Auto-generated method stub
?????? Users users = null;
?????? try {
?????????? String hql = "from Users as u where u.username = ?";
?????????? List list = this.getHibernateTemplate().find(hql,username);
?????????? if(list!=null && list.size()>0){
????????????? users = (Users)list.get(0);
?????????? }
?????? } catch (DataAccessException e) {
?????????? // TODO Auto-generated catch block
?????????? e.printStackTrace();
?????? }
?????? return users;
??? }
???
??? public Users getUser(String username, String password) {
?????? // TODO Auto-generated method stub
?????? Users users = null;
?????? try {
?????????? String hql = "from Users as u where u.username = ? and u.password = ?";

??? }
???
??? public boolean saveUser(Users users) {

}
注意：
此处的HibernateDaoSupport 的路径可能有多个（可能导入了许多其它的包），注意此处的父类
为org.springframework.orm.hibernate3.support.HibernateDaoSupport
而不是org.springframework.orm.hibernate.support.HibernateDaoSupport
