struts2+Hibernate实现用户登陆功能

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

model层

User

package com.zs.model;

public class User {

    private String username;

    private String password;

    private Short sex;

    private String email;

    private String address;

    private String grade;

    public void setUsername(String username) {

        this.username = username;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    public Short getSex() {

    }

    public void setSex(Short sex) {

        this.sex = sex;

    }

    public String getEmail() {

        return email;

Hibernate：

配置hibernate.hbm.xml：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE hibernate-configuration PUBLIC

        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <!--数据库映射Java用户-->

        <mapping resource="com/zs/model/User.hbm.xml" />

Struts：

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC

    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"

    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>

    <package name="default" extends="struts-default">

        <!--登陆主页面时候的Action-->

        <action name="index">

            <result>/index.jsp</result>

        </action>

        <!--在index.jsp提交submit后若登陆成功则转到adminlogin,否则转到index-->

        <action name="userlogin" class="com.zs.web.admin.AdminLoginAction">

            <result name="success">/admin/adminlogin.jsp</result>

            <result name="input">/index.jsp</result>

        </action>

    </package>

</struts>

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;

import com.zs.model.User;

public class AdminLoginAction extends ActionSupport implements SessionAware {

    /**

     *

     */

    private static final long serialVersionUID = 1L;

    UserDao dao = new UserDaoImpl();

    private String username;

    private String password;

    private Map<String,Object> session;

    public String execute(){

            User user = dao.isValidAdmin(username, password);//将username和password传递到dao层交个hibernate判断

            if(user!=null){

                session.put("user", user);//若登陆成功则将该user记录在session中

                return SUCCESS;

            }else{

                addActionError("你没有管理权限");

                return INPUT;

            }

    }

    public String getUsername() {

        return username;

    }

    public void setUsername(String username) {

        this.username = username;

    }

    public String getPassword() {

        return password;

    }

    public void setPassword(String password) {

        this.password = password;

    }

    public Map getSession() {

        return session;

    }

    public void setSession(Map session) {

        this.session = session;

    }

}

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;

import com.zs.dao.UserDao;

import com.zs.model.User;

public class UserDaoImpl extends BaseDaoImpl implements UserDao {

    @Override

    public void saveUser(User user) {

        // 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
