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：
<action
attribute="loginForm"
input="/login.jsp"
name="loginForm"
path="/login"
scope="request"
validate="true"
type="com.test.struts.action.LoginAction" /> </action-mappings>
改为：
<action
attribute="loginForm"
input="/login.jsp"
name="loginForm"
path="/login"
scope="request"
validate="true"
type="org.springframework.web.struts.DelegatingActionProxy" />
</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">
<beans>
<bean name="/login" class="net.xiaxin.action.LoginAction" singleton="false"></bean>
</beans>
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 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;
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"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>

<value>root</value>
</property>
<property name="password">

</property>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">

</property>
<property name="mappingResources">

</list>
</property>
<property name="hibernateProperties">

<prop key="hibernate.dialect">net.sf.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate.HibernateTransactionManager">
<property name="sessionFactory">

</property>
</bean>
<bean id="userDAO" class="com.test.UserDAOImp">
<property name="sessionFactory">
<ref local="sessionFactory" />
</property>
</bean>
<bean id="userDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="target">
<ref local="userDAO" />
</property>
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="is*">PROPAGATION_REQUIRED,readOnly</prop>
</props>
</property>
</bean> <bean name="/login" class="com.test.struts.action.LoginAction" singleton="false">
<property name="userDAO">
<ref bean="userDAOProxy" />
</property>
</bean>
</beans>
现在可以进行测试了！
