userdao.java

简单的SSH登陆其中用到Spring、Struts、hibernate

package com.frank.rule;

import org.springframework.orm.hibernate3.HibernateTemplate;

import com.frank.entity.MyUser;
import java.util.*;

public class UserDAO {
	private HibernateTemplate hibernateTemplate;

	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}

	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}
	public boolean login(MyUser user){
		try{
			
			String queryString="from MyUser as user where user.username='"+user.getUsername()
			+"' and user.userpass='"+user.getUserpass()+"'";
			List list=hibernateTemplate.find(queryString);
			if(list.size()>0){
				return true;
			}else{
				return false;
			}
		}catch(Exception ex){
			ex.printStackTrace();
			return false;
		}
	}
	public boolean insertUser(MyUser user){
		try{
			MyUser newUser=new MyUser();
			newUser.setUsername(user.getUsername());
			newUser.setUserpass(user.getUserpass());
			hibernateTemplate.save(newUser);
			return true;
		}catch(Exception ex){
			ex.printStackTrace();
			return false;
		}
	}
}
