本示例是 Spring+Struts+Hibernate 整合来编写一个用户注册的简单示例 , 项目名称为 mySSH, 示例中连接的数据库为 MySQL, 使用前应在 MySQL 中创建一个数据库 mySSH,mySSH 中创建数据库表 user,SQL 语句如下 ,CREATE TABLE ‘user’(‘id’ VARCHAR(32)NOT MULL,’username’ VARCHAR(32) NOT NULL,’password’ VARCHAR(32) NOT NULL,PRIMARY KEY (‘id’))ENGINE=MYISAM; 示例的简单代码如下 :

 

< 一 > 在 mySSH/WEB-INF 目录下编写 web.xml

 

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

< web-app xmlns = "http://java.sun.com/xml/ns/j2ee"

xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"

version = "2.4"

xsi:schemaLocation = "http://java.sun.com/xml/ns/j2ee  

http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >

 < servlet >

    < servlet-name > actionServlet </ servlet-name >

 < servlet-class > org.apache.struts.action.ActionServlet </ servlet-class >

    < init-param >

      < param-name > config </ param-name >

      < param-value > /WEB-INF/struts-config.xml </ param-value >

    </ init-param >

    < load-on-startup > 1 </ load-on-startup >

 </ servlet >

 < servlet-mapping >

    < servlet-name > actionServlet </ servlet-name >

    < url-pattern > *.do </ url-pattern >

 </ servlet-mapping >

</ web-app >

 

< 二 > 在 mySSH/WEB-INF/jsp 目录下编写用户注册页面 regedit.jsp

 

<%@ page contentType = "text/html;charset=GBK" %>

< html >

< head >< title > Spring,Struts 和 Hibernate 整合实例 </ title ></ head >

<%

   String msg=request.getAttribute( "msg" )== null ? "" :(String)request.getAttribute( "msg" );

%>

< body > <%= msg %>

   < form action = "/mySSH/regedit.do" method = "post" >

      用户名 : < input type = "text" name = "name" value = "${user.username }"/><br>

      密码 : < input type = "password" name = "password" value = "" />< br >

      < input type = "submit" name = "method" value = " 提交 " />

   </ form >

</ body >

</ html >

 

< 三 > 在 mySSH/WEB-INF/jsp 目录下编写用户注册成功页面 success.jsp

 

<%@ page contentType = "text/html;charset=GBK" %>

< html >

< head >< title > Spring,Struts 和 Hibernate 整合实例 </ title ></ head >

< body >

    提交成功 : 你输入的用户名是 :${user.name }, 密码是 :${user.password }

</ body >

</ html >

 

< 四 > 在 com.gc.vo 包下编写 POJO---User.java

 

package com.gc.vo;

public class User {

    private String id ;

    private String username ;

    private String password ;

    public User(String username,String password){

       this . username =username;

       this . password =password;

    }

    public User(){

      

    }

    public String getId() {

       return id ;

    }

    public void setId(String id) {

       this . id = id;

    }

    public String getPassword() {

       return password ;

    }

    public void setPassword(String password) {

       this . password = password;

    }

    public String getUsername() {

       return username ;

    }

    public void setUsername(String username) {

       this . username = username;

    }  

}

 

< 五 > 在 com.gc.vo 包下编写映射文件 User.hbm.xml

 

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

<! DOCTYPE hibernate-mapping PUBLIC

"-//Hibernate/Hibernate Mapping DTD 2.0//EN"

"http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >

< hibernate-mapping >

   < class name = "com.gc.vo.User" table = "user" >

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

        < generator class = "uuid.hex" ></ generator >

      </ id >

      < property name = "username"

                type = "java.lang.String"

                column = "username"

                not-null = "true"

                length = "32" >

      </ property >

      < property name = "password"

                type = "java.lang.String"

                column = "password"

                not-null = "true"

                length = "32" >

      </ property >

   </ class >

</ hibernate-mapping >

 

< 六 > 在 com.gc.dao 包下编写接口类 UserDAO.java

 

package com.gc.dao;

import com.gc.vo.*;

public interface UserDAO {

    // 新增用户

    public abstract void createUser(User user);

    // 修改用户

    public abstract void updateUser(User user);

    // 删除用户

    public abstract void deleteUser(User user);

    // 查询用户

    public abstract User queryUser(String name);

}

 

< 七 > 在 com.gc.dao.impl 包下编写接口类 UserDAO 的实现类 UserDAOImpl.java

 

package com.gc.dao.impl;

import com.gc.dao.UserDAO;

import com.gc.vo.User;

import java.util.ArrayList;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import org.springframework.orm.toplink.SessionFactory;

public class UserDAOImpl extends HibernateDaoSupport implements UserDAO{

    // 依赖注入 SessionFactory

    private SessionFactory sessionFactory ;

    // 定义查询 SQL 语气

    private String SQL = "from user u where u.username=?" ;

    // 新增用户

    public void createUser(User user){

       this .getHibernateTemplate().save(user);

    }

    // 修改用户

    public void updateUser(User user){

       this .getHibernateTemplate().update(user);

    }

    // 删除用户

    public void deleteUser(User user){

       this .getHibernateTemplate().delete(user);

    }

    // 查询用户

    public User queryUser(String name){

       List userList;

       if ( this .getHibernateTemplate().find( SQL , name)== null )

           userList= new ArrayList();

       else

           userList= this .getHibernateTemplate().find( SQL , name);

       return (User)userList.get(0);

    }

}

 

< 八 > 在 mySSH/WEB-INF 目录下编写 Struts 的配置文件 struts-config.xml

 

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

<! DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
