Struts 2 + Hibernate 用户的登录与注销

 1.反向工程生成用户实体类

User.java

package com.sunline.entity;/** * User entity. @author MyEclipse Persistence Tools */public class User  implements java.io.Serializable {    // Fields         private Integer userId;     private String userName;     private String userPassword;     private String userStatus;    // Constructors    /** default constructor */    public User() {    }        /** full constructor */    public User(String userName, String userPassword, String userStatus) {        this.userName = userName;        this.userPassword = userPassword;        this.userStatus = userStatus;    }       // Property accessors    public Integer getUserId() {        return this.userId;    }        public void setUserId(Integer userId) {        this.userId = userId;    }    public String getUserName() {        return this.userName;    }        public void setUserName(String userName) {        this.userName = userName;    }    public String getUserPassword() {        return this.userPassword;    }        public void setUserPassword(String userPassword) {        this.userPassword = userPassword;    }    public String getUserStatus() {        return this.userStatus;    }        public void setUserStatus(String userStatus) {        this.userStatus = userStatus;    }}

User.hbm.xml

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><!--     Mapping file autogenerated by MyEclipse Persistence Tools--><hibernate-mapping>    <class name="com.sunline.entity.User" table="user" catalog="hengfeng">        <id name="userId" type="java.lang.Integer">            <column name="user_id" />            <generator class="native"></generator>        </id>        <property name="userName" type="java.lang.String">            <column name="user_name" length="40" not-null="true" />        </property>        <property name="userPassword" type="java.lang.String">            <column name="user_password" length="30" not-null="true" />        </property>        <property name="userStatus" type="java.lang.String">            <column name="user_status" length="30" not-null="true" />        </property>    </class></hibernate-mapping>

Hibernate配置文件

Hibernate.cfg.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"><!-- Generated by MyEclipse Hibernate Tools.                   --><hibernate-configuration><session-factory><property name="dialect">org.hibernate.dialect.MySQLDialect</property><property name="connection.url">jdbc:mysql://localhost:3306/hengfeng?characterEncoding=UTF-8</property><property name="connection.username">root</property><property name="connection.password">******</property><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="myeclipse.connection.profile">com.mysql.jdbc.Driver</property><property name="show_sql">true</property><property name="format_sql">true</property><property name="hbm2ddl.auto">update</property><mapping resource="com/sunline/entity/Basedata.hbm.xml" /><mapping resource="com/sunline/entity/Targetdimension.hbm.xml" /><mapping resource="com/sunline/entity/User.hbm.xml" /></session-factory></hibernate-configuration>

Struts 2 配置文件

Struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts><package name="SunlineShow" extends="struts-default">   <!-- 登录 -->   <action name="Main" class="com.sunline.action.LoginAction"><result name="success">/jsp/Main.jsp</result><result name="error">/error.jsp</result></action>      <!-- 注销登录 -->   <action name="LogOut" class="com.sunline.action.LogoutAction"><result name="success">/index.jsp</result></action></package></struts>    

Hibernate配置文件解析类

HibernateSessionFactory.java

package com.sunline.dao;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.cfg.Configuration;public class HibernateSessionFactory {    private SessionFactory sessionFactory;    public HibernateSessionFactory(){            }        public SessionFactory config(){        try{            Configuration configuration= new Configuration();            Configuration configure=configuration.configure("hibernate.cfg.xml");            return configure.buildSessionFactory();        }catch(Exception e){        e.getMessage();        return null;        }    }        public Session getSession(){        sessionFactory=config();        return sessionFactory.openSession();    }}

数据访问层Dao类

UserDao.java

package com.sunline.dao;import java.util.List;import org.hibernate.Query;import org.hibernate.Session;import org.hibernate.Transaction;import com.sunline.entity.User;public class UserDao {private Session session;private Transaction transaction;private Query query;HibernateSessionFactory getSession;    public List<User> Login(String user_name,String user_password){    getSession = new HibernateSessionFactory();    session = getSession.getSession();        try{            String hqlsql="from User as u where u.userName=? and u.userPassword=?";            query=session.createQuery(hqlsql);            query.setParameter(0, user_name);            query.setParameter(1, user_password);            List<User> list=query.list();            transaction=session.beginTransaction();            System.out.println("查询成功!");            transaction.commit();            return list;        }catch(Exception e){            System.out.println("查询错误!");            e.printStackTrace();            return null;        }    }}

Action控制类

登录控制类:

LoginAction.java

package com.sunline.action;import java.util.List;import java.util.Map;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;import com.sunline.dao.UserDao;import com.sunline.entity.User;public class LoginAction extends ActionSupport {private static final long serialVersionUID = 1889710968497585080L;private String user_name ;private String user_password;public String getUser_name() {return user_name;}public void setUser_name(String user_name) {this.user_name = user_name;}public String getUser_password() {return user_password;}public void setUser_password(String user_password) {this.user_password = user_password;}@Overridepublic String execute() throws Exception {// TODO Auto-generated method stubUserDao dao = new UserDao();List<User> list = dao.Login(this.user_name, this.user_password);if(list.size()>=1){ActionContext context = ActionContext.getContext();Map<String, Object> session = context.getSession();//session.put("user",list);session.put("user",this.user_name);return SUCCESS;}else{return ERROR;}}}

注销控制类:

LogoutAction.java

package com.sunline.action;import java.util.Map;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;public class LogoutAction extends ActionSupport {private static final long serialVersionUID = 1L;@Overridepublic String execute() throws Exception {// TODO Auto-generated method stub        Map session = ActionContext.getContext().getSession();         session.remove("user"); return SUCCESS;}    }
