現在創建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>

 

改為：

<action
      attribute="loginForm"
      input="/login.jsp"
      name="loginForm"
      path="/login"
      scope="request"
      validate="true"
      type="org.springframework.web.struts.DelegatingActionProxy" />

  </action-mappings>

 

綠色字體部份為修改內容

這里將使用spring的代理器來對Action進行控制

 

當提交到/login.do是將控制權交給了spring，然后由spring來決定是否轉回到struts的Action

 

現在來配置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>

 

綠色字體是關于轉交控制權的配置內容

 

屬性singleton="false"，指明了Action 的實例獲取方式為每次重新創建。解決了Struts中令人詬病的線程安全問題（Struts中，由一個Action實例處理所有的請求，這就導致了類公用資源在并發請求中的線程同步問題。）（摘自spring開發指南）

 

建立數據庫在 這里我使用的是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;

 

創建Hibernate框架

使用MyEclipse的數據Database Explorer工具創建User.hmb.xml、AbstractUser.java、User.java映射文件

創建完成后可以將自動生成的hibernate.cfg.xml刪除

 

創建UserDAO.java、UserDAOImp.java

 

修改LoginAction.java文件，使用userDao的方法來進行用戶驗證

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 {

 private UserDAO userDAO;

 

 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();
  }
 }

}
綠色字體為修改部份

 

現在剩下最后的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>
  </property>
  <property name="url">
   <value>jdbc:mysql://localhost:3306/test</value>
  </property>
  <property name="username">
   <value>root</value>
  </property>
  <property name="password">
   <value></value>
  </property>
 </bean>

 

 <bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
  <property name="dataSource">
   <ref local="dataSource" />
  </property>
  <property name="mappingResources">
   <list>
    <value>com\test\Hibernate\User.hbm.xml</value>
   </list>
  </property>
  <property name="hibernateProperties">
   <props>
    <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">
   <ref local="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>

 

現在可以進行測試了！
