struts2+hibernate整合-实现登录功能

最近一直学习struts2+hibernate框架，于是想把两个框架整合到一起，做一个小的登录项目。其他不多说，直接看例子。

1）、Struts2 和hibernate的环境配置

　　包括jar包、web.xml以及hibernate.cfg.xml的配置，前面的文章有详细的讲述，这里就不在一一叙述。

2）、登录界面实现（使用了bootstrap自适应框架，详细内容见官网http://www.bootcss.com/）

<!doctype html>

<html lang="en">

<head>

<meta charset="UTF-8">

<title>登录</title>

<link rel="stylesheet" href="styles/bootstrap.min.css">

<link rel="stylesheet" href="styles/MyOwn.css">

</head>

<body>

    <nav class="navbar navbar-inverse navbar-fixed-top" role="navigation">

        <div class="navbar-header"></div>

    </nav>

    <div class="login-page  center-block">

        <div class="center-container">

            <h2 class="color text-center">登录系统</h2>

            <form class="form-horizontal center-block" role="form"

                action="login.action">

                <div class="form-group ">

                    <label class="col-sm-2 control-label">用户名</label>

                    <div class="col-sm-8">

                        <input type="text" class="form-control col-lg-sm" id="name"

                            name="username" placeholder="用户名">

                    </div>

                </div>

                <div class="form-group">

                    <label for="inputPassword3" class="col-sm-2 control-label">密码</label>

                    <div class="col-sm-8">

                        <input type="password" class="form-control" id="inputPassword3"

                            name="pwd" placeholder="密码">

                    </div>

                </div>

                <div class="form-group">

                    <div class="col-sm-offset-2 col-sm-10">

                        <div class="checkbox col-sm-5">

                            <label> <input type="checkbox"> 记住密码

                            </label>

                        </div>

                        <a class=" col-sm-4 control-label" href="register.html">新用户注册</a>

                    </div>

                </div>

                <div class="form-group ">

                    <div class="col-sm-8 col-sm-offset-2">

                        <button type="submit" class="btn btn-primary btn-block" id="btn">登录</button>

                    </div>

                </div>

            </form>

        </div>

    </div>

</body>

3）、生成实体类的对象关系映射文件，用户（ User.java）以及对应的User.hbm.xml

package com.entity;

public class User {

    private Integer id;

    private String username;

    private String pwd;

    public Integer getId() {

        return id;

    }

    public void setId(Integer id) {

        this.id = id;

    }

    public String getUsername() {

        return username;

    }

    public void setUsername(String username) {

        this.username = username;

    }

    public String getPwd() {

        return pwd;

    }

    public void setPwd(String pwd) {

        this.pwd = pwd;

    }

    public User(String username,String pwd) {

        this.username = username;

        this.pwd = pwd;

    }

    public User() {

        // TODO Auto-generated constructor stub

    }

}
<?xml version="1.0"?>

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

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

<!-- Generated 2016-11-26 16:32:02 by Hibernate Tools 3.4.0.CR1 -->

<hibernate-mapping>

    <class name="com.entity.User" table="USER">

        <id name="id" type="java.lang.Integer">

            <column name="ID" />

            <generator class="native" />

        </id>

        <property name="username" type="java.lang.String">

            <column name="USERNAME" />

        </property>

            <column name="PWD" />

        </property>

    </class>

</hibernate-mapping>

4）、创建用户自定义SessionFactory工厂（Hibernateutil.java）

package com.util;

import org.hibernate.SessionFactory;

import org.hibernate.boot.registry.StandardServiceRegistry;

import org.hibernate.boot.registry.StandardServiceRegistryBuilder;

import org.hibernate.cfg.Configuration;

public class Hibernateutil {

    private static SessionFactory sessionFactory = null;

    // 采用单例模式

    private Hibernateutil() {

    }

    public static SessionFactory getSessionFactory() {

        if (sessionFactory == null) {

            // 创建Configuration对象:对应hibernate的基本配置信息和对象关系映射信息

            Configuration config = new Configuration().configure();

            // 创建一个对象StandardServiceRegistry，configure("你的***.cfg.xml")，默认为hibernate.cfg.xml

            StandardServiceRegistry registry = new StandardServiceRegistryBuilder()

                    .configure().build();

            // 创建会话工厂对象

            sessionFactory = config.buildSessionFactory(registry);

            return sessionFactory;

        } else

            return sessionFactory;

    }

}

5）、创建用户业务逻辑接口和类(UserImpl.java和UserDao.java)

UserImpl.java

package com.service.impl;

import com.entity.User;

//用户业务逻辑接口

public interface UserImpl {

    // login登录

    public boolean Login(User user);

　　//注册

    public boolean Register(User user);

}

UserDao.java

package com.service.dao;

import java.util.List;

import org.hibernate.Session;

import org.hibernate.Transaction;

import org.hibernate.query.Query;

import com.entity.User;

import com.service.impl.UserImpl;

import com.util.Hibernateutil;

public class UserDao implements UserImpl {

    private Transaction ts = null;

    private String sql = "";

    private Session session = null;

    @Override

    public boolean Login(User user) {

        try {

            getSession();

            sql = "select username,pwd from User where username=?and pwd=?";

            Query query = session.createQuery(sql);

            query.setParameter(0, user.getUsername());

            query.setParameter(1, user.getPwd());

            List list = query.list();

            ts.commit();

            if (!list.isEmpty())

                return true;

            else

                return false;

        } catch (Exception ex) {

            ex.printStackTrace();

            return false;

        } finally {

            session.close();

        }

    }

    @Override

    public boolean Register(User user) {

        // TODO Auto-generated method stub

        try {

            getSession();

            session.save(user);

            return true;

        } catch (Exception ex) {

            ex.printStackTrace();

            return false;

        } finally {

            session.close();

        }

    }

    public void getSession() {

        session = Hibernateutil.getSessionFactory().openSession();

        ts = session.beginTransaction();

    }

}

6）、设计用户Action类

UserAction.java

package com.action.userAction;

import java.util.Map;

import javax.enterprise.event.Observes;

import org.apache.struts2.interceptor.RequestAware;

import com.entity.User;

import com.service.dao.UserDao;

public class UserAction implements RequestAware {

    private String username;

    private String pwd;

    private Map<String, Object> request;

    public String getUsername() {

        return username;

    }

    public void setUsername(String username) {

        this.username = username;

    }

    public String getPwd() {

        return pwd;

    }

    public void setPwd(String pwd) {

        this.pwd = pwd;

    }

    public String Login() {

        UserDao userDao = new UserDao();

        User user = new User();

        user.setUsername(username);

        user.setPwd(pwd);

        if (userDao.Login(user)) {

            request.put("username", username);

            return "success";

        } else

            return "error";

    }

    public String Register() {

        UserDao userDao = new UserDao();

        User user = new User();

        user.setUsername(username);

        user.setPwd(pwd);

        if(userDao.Register(user)){

            return "success";

        }else

        return "failure";

    }

    @Override

    public void setRequest(Map<String, Object> request) {

        // TODO Auto-generated method stub

        this.request = request;

    }

}

7）、注册struts.xml

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

<!DOCTYPE struts PUBLIC

        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"

        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>

    <!-- 配置扩展名 -->

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

        <action name="login" class="com.action.userAction.UserAction" method="Login">

            <result name="success">/index.html</result>

            <result name="error">/register.jsp</result>

        </action>

        <action name="register" class="com.action.userAction.UserAction" method="Register">

            <result name="success">/index.html</result>

            <result name="failure">/login.html</result>

        </action>

    </package>

</struts>
