struts+hibernate+spring一个入门的实用例子(上)

环境:eclipse3.2+myeclipse5.0m2,在tomcat上顺利运行,为了简便开发,这一个例子我没有写业务逻辑层,而且包名的设置也不太合理，各位可以自行修改.构造好开发环境,把需要的jar导入web project中.
1、创建一个名叫demo数据库,这里用mysql
    再创建一个表:
    create table user
(
         id  int(15) not null auto_increment,
         username varchar(50) not null,
        password varchar(50) not null,
        primary key(id)
)type=INNODB;
记得type要设为innodb或bdb类型的，不然的话不支持数据库事务.

2、domain层和DAO层.
使用MyEclipse的数据Database Explorer工具创建User.hmb.xml、AbstractUser.java、User.java映射文件。具体文件如下:
AbstractUser.java文件：
package com.test;

/**
* AbstractUser generated by MyEclipse - Hibernate Tools
*/

public abstract class AbstractUser implements java.io.Serializable {

// Fields

     private Integer id;
     private String username;
     private String password;

// Constructors

    /** default constructor */
    public AbstractUser() {
    }

    /** full constructor */
    public AbstractUser(Integer id, String username, String password) {
        this.id = id;
        this.username = username;
        this.password = password;
    }

// Property accessors

    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUsername() {
        return this.username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

User.java文件
package com.test;
// Generated by MyEclipse - Hibernate Tools

/**
* User generated by MyEclipse - Hibernate Tools
*/
public class User extends AbstractUser implements java.io.Serializable {

// Constructors

    /** default constructor */
    public User() {
    }

/** full constructor */
    public User(Integer id, String username, String password) {
        super(id, username, password);
    }
}

User.hbm.xml文件
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd提示：User.java,和User.hbm.xm两个文件放在同一个包文件夹里面。

接下来是创建UserDAO接口,和UserDAO接口的实现UserDAOImp.
UserDAO文件:
package com.test;">

<hibernate-mapping>
    <class name="com.test.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" length="50" not-null="true" />
        </property>
        <property name="password" type="java.lang.String">
            <column name="password" length="50" not-null="true" />
        </property>
    </class>
</hibernate-mapping>

publicinterface UserDAO {

publicabstractboolean isValidUser(String username,String password);

}

UserDAOImp文件,主要是用来验证用户名和密码正确不:

package com.test;

import org.hibernate.Query;

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

public class UserDAOImp extends HibernateDaoSupport implements UserDAO{

private static String hql = "from User as u where u.username=:userName"+" and u.password=:passWord";

public boolean isValidUser(String username, String password) {

Query query= this.getHibernateTemplate().getSessionFactory().getCurrentSession().createQuery(hql);

query.setString("userName", username);

query.setString("passWord", password);

return (query.list().size()>0);

}

我把配置文件放在最后才说,即是spring的的配置文件,这里利用spring来管理hibernate的dataSource和事务管理.

3、创建strutsMVC的框架的一些具体实现内容，把struts中的action控制放在spring中去配置，因为可以利用spring中DI或IoC的功能.

新建一个index.jsp文件,如下所示：
<%@ page language="java" pageEncoding="UTF-8"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>

<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>My JSP 'index.jsp' starting page</title>

</head>

<body>

<a href="login.jsp">进入登录系统</a>

</body>

</html>

再创建一个login.jsp文件

<%@ page language="java" pageEncoding="utf-8"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>

<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html lang="true">

<head>

<html:base />

<title>login.jsp</title>

</head>

<body>

<html:form action="/login">

username : <html:text property="username"/><html:errors property="username"/><br/>

password : <html:password property="password"/><html:errors property="password"/><br/>

<html:submit/><html:cancel/>

</html:form>

</body>

</html:html>

登录成功后的success.jsp
<%@ page language="java" pageEncoding="UTF-8"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>

<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>

<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>

<%@ taglib uri="http://struts.apache.org/tags-tiles" prefix="tiles" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html:html lang="true">

<head>

<html:base />

<title>success.jsp</title>

<!--

-->

</head>

<body>

Welcome!<br/>

<logic:present name="loginForm">

欢迎你,<bean:write name="loginForm" property="username"/>

</logic:present>

</body>

</html:html>
