实现的功能，在登陆页面输入Username和PassWord后，将username和password通过Hibernate匹对数据库是否含有一样的username和password，若有则登陆进去，若没有则返回到登陆页面

Action:
package com.zs.web.admin;
import java.util.Map;
import org.apache.struts2.interceptor.SessionAware;
import com.opensymphony.xwork2.ActionSupport;
import com.zs.dao.UserDao;
import com.zs.dao.impl.UserDaoImpl;

判断用户和密码是否存在于数据库中
package com.zs.dao.impl;
import java.util.List;
import com.zs.dao.BaseDaoImpl;

// TODO Auto-generated method stub
}
@Override
public List<User> getAll(Class clazz) {
// TODO Auto-generated method stub
return null;
}
@Override
public User isValidUser(String username, String password) {
// TODO Auto-generated method stub
return null;
}
//判断数据库中时候含有该用户
@Override
public User isValidAdmin(String username, String password) {
User user = null;
//调用hibernate
List<User> list =super.search("FROM User WHERE grade=‘admin‘ AND username =‘"+username+"‘ AND password = ‘"+password+"‘");
if(list!=null && list.size()>0){//若找到的list不为空那么则说明数据库中包含这个人
user = list.get(0);
}
return user;
}
}
Hibernate初始化借口并且从数据库中取数据
package com.zs.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
public class BaseDaoImpl implements IBaseDao {
private SessionFactory sessionFactory;
private Session session;
private Transaction transaction;
//初始session接口
public void init(){
Configuration configuration = new Configuration().configure();
ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties())
.buildServiceRegistry();
sessionFactory = configuration.buildSessionFactory(serviceRegistry);
session = sessionFactory.openSession();
transaction = session.beginTransaction();
}
@Override
public Session getSession() {
init();
return session;
}
@Override
public void closeSession() {
session.close();
}
@Override
public List search(String hql) {
//调用session接口
Session session = null;
session = getSession();
List alist = null;
alist = session.createQuery(hql).list();//从数据库中查询
session.close();
return alist;
}
}
可以先建好一个名为User的数据库，设置一个用户，然后便可以测试了
