环境：Windows2003&jdk1.5.05&Eclipse3.1+MyEclipse4.03

做一登录练习。

现已经完成了login的struts部份，实现了动态ActionForm和动态validator验证，详细全部文件内容如下：

struts-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.1//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_1.dtd">

<struts-config>
<data-sources />
<form-beans >
    <form-bean name="loginForm" type="org.apache.struts.validator.DynaValidatorForm">
      <form-property name="password" type="java.lang.String" />
      <form-property name="username" type="java.lang.String" />
    </form-bean>

</form-beans>

<global-exceptions />
<global-forwards >
<forward name="indexGo" path="/index.jsp" />
</global-forwards>

<action-mappings >
    <action
      attribute="loginForm"
      input="/login.jsp"
      name="loginForm"
      path="/login"
      scope="request"
      validate="true"
      type="com.test.struts.action.LoginAction" />
</action-mappings>

<message-resources parameter="com.test.struts.ApplicationResources" />
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames" value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />
</plug-in>
</struts-config>

index.jsp

<head>

<a href="login.jsp">Login</a>

LoginAction.java

//Created by MyEclipse Struts
// XSL source (default): platform:/plugin/com.genuitec.eclipse.cross.easystruts.eclipse_4.0.1/xslt/JavaClass.xsl

package com.test.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.validator.DynaValidatorForm;

/**
* MyEclipse Struts
* Creation date: 10-27-2005
*
* XDoclet definition:
* @struts.action path="/login" name="loginForm" input="login.jsp" scope="request" validate="true"
*/
public class LoginAction extends Action {

// --------------------------------------------------------- Instance Variables

// --------------------------------------------------------- Methods

/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) {
DynaValidatorForm loginForm = (DynaValidatorForm) form;
// TODO Auto-generated method stub
String username=(String)loginForm.get("username");
String password=(String)loginForm.get("password");
loginForm.set("password",null);
if(username.equals("sonic")||password.equals("sonic")){
   System.out.println("AAA");
   return mapping.findForward("indexGo");
}
else {
   System.out.println("BBB");
   return mapping.getInputForward();
}
}

}

ApplicationResources.properties

prompt.username=User Name
prompt.password=User Password

errors.required={0} is required.

ApplicationResources_zh_CN.properties

prompt.username=用户名称
prompt.password=登录密码

errors.required={0} 是必须的.

validation.xml

<form-validation>
<formset>
<form name="loginForm">
   <field property="username" depends="required">
    <arg0 key="prompt.username" />
   </field>
   <field property="password" depends="required">
    <arg0 key="prompt.password" />
   </field>
</form>
</formset>
</form-validation>

到此已经完成了全部代码！

********************************************************************
现在创建spring框架

配置struts-config.xml文件，添加（spring）的插件

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/applicationContext.xml" />
</plug-in>

修改LoginAction配置

原：

改为：

</action-mappings>

绿色字体部份为修改内容

这里将使用spring的代理器来对Action进行控制

当提交到/login.do是将控制权交给了spring，然后由spring来决定是否转回到struts的Action

现在来配置spring

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

绿色字体是关于转交控制权的配置内容属性singleton="false"，指明了Action 的实例获取方式为每次重新创建。解决了Struts中令人诟病的线程安全问题（Struts中，由一个Action实例处理所有的请求，这就导致了类公用资源在并发请求中的线程同步问题。）（摘自spring开发指南）

建立数据库在这里我使用的是mysql4.1.1x

CREATE TABLE `user` (
`ID` int(11) NOT NULL auto_increment,
`USERNAME` varchar(50) NOT NULL default '',
`PASSWORD` varchar(50) NOT NULL default '',
PRIMARY KEY (`ID`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

创建Hibernate框架

使用MyEclipse的数据Database Explorer工具创建User.hmb.xml、AbstractUser.java、User.java映射文件

创建完成后可以将自动生成的hibernate.cfg.xml删除

创建UserDAO.java、UserDAOImp.java

修改LoginAction.java文件，使用userDao的方法来进行用户验证

package com.test.struts.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.test.UserDAO;

public class LoginAction extends Action {
public UserDAO getUserDAO() {
return userDAO;
}

public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}

public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
DynaValidatorForm loginForm = (DynaValidatorForm) form;
// TODO Auto-generated method stub
String username = (String) loginForm.get("username");
String password = (String) loginForm.get("password");
loginForm.set("password", null);
if (userDAO.isValidUser(username,password)) {
   return mapping.findForward("indexGo");
} else {
   return mapping.getInputForward();
}
}

}
绿色字体为修改部份

现在剩下最后的spring配置了

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