package org.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import springDao.Sstest;
import springDao.SstestDAO;

public class SpringDaoTest {
 public static void main(String a[]){
  ApplicationContext cont = new ClassPathXmlApplicationContext("applicationContext.xml");
  SstestDAO  s = (SstestDAO) cont.getBean("SstestDAO");
   SstestDAO  s = (SstestDAO) cont.getBean("SstestDAOProxy");
  Sstest st = new Sstest();
  st.setUsername("spring");
  st.setPassword("spring");
  s.save(st);   
 } 
}
六、由于映射了两次，所以你要在hibernate.cfg.xml文件中，把原来映射的文件注解掉：
<mapping resource="hibernateDao/Sstest.hbm.xml" />
因为现在已有一行这样的代码：
<mapping resource="springDao/Sstest.hbm.xml" />
七、实现hibernate spring 代理，加上下面的代码即可：
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
  <property name="sessionFactory">
   <ref local="sessionFactory"/>
  </property>
 </bean>
 <bean id="SstestDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  <property name="proxyTargetClass">
   <value>true</value>
  </property>
  <property name="transactionManager">
   <ref bean="transactionManager"/>
  </property>
  <property name="target">
   <ref local="SstestDAO"/>
  </property>
  <property name="transactionAttributes">
   <props>
    <prop key="*">PROPAGATION_REQUIRED</prop>
   </props>
  </property>
 </bean>
在进行测试，测试时，还是用原来的类，只需把SstestDAO  s = (SstestDAO) cont.getBean("SstestDAO");变成
SstestDAO  s = (SstestDAO) cont.getBean("SstestDAOProxy");这次的bean是用的代码类实现
下面是完整的代码：
在这个实例中hibernate包中的文件BaseHibernateDAO. ,HibernateSessionFactory ,IBaseHibernateDAO, Sstest,SstestDAO, Sstest.hbm.xml ，和在一个简单的struts，hibernate例子以及struts,hibernate集成中的文件是一样的，代码一样，下面是一些其它代码：

  </head> 
  <body>
   <h2>用户信息</h2>
    用户名：<s:property value="username" escape="request"/>
    密码：${requestScope.password }
  </body>
</html>

该把修改web.xml，把原来的
<filter-mapping>
  <filter-name>struts</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>
改为
<filter-mapping>
  <filter-name>struts</filter-name>
  <url-pattern>*.action</url-pattern>
 </filter-mapping>
而上传页面调用时直接用文件名调用（如upload.jsp）。struts2只处理 *.action 的请求。
或者
<filter>
<filter-name>struts2</filter-name>
<filter-class>
org.apache.struts2.dispatcher.FilterDispatcher
</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
去掉也行

若是java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileUploadException错误
那就有可能是导包的问题，若用的是右击项目，选择属性，然后导入相应的包，就有可能出显此类的错误，解决方法是：把commons-fileupload-1.2.1.jar,commons-io-1.4.jar复制到到WEB-INF下的lib目录中，虽然效果是一样，但不会出错了

　　OSGi(基于Java的动态模型规范)

　　注：OSGi(Open Service Gateway Initiative)指OSGi Alliance组织制定的一个基于Java语言的服务(业务)规范——OSGi服务平台(Service Platform)。 该规范和核心部分是一个框架 ，其中定义了应用程序的生命周期模式和服务注册。这个框架实现了一个优雅、完整和动态的组件模型。应用程序(称为bundle)无需重新引导可以被远程安装、启动、升级和卸载(其中Java包/类的管理被详细定义)。API中还定义了运行远程下载管理政策的生命周期管理。服务注册允许bundles去检测新服务和取消的服务，然后相应配合。

　　Java内容仓库，最早于2002年2月由JCP发布

　　注：JCP(Java Community Process) 是一个开放的国际组织，主要由Java开发者以及被授权者组成，职能是发展和更新Java技术规范、参考实现(RI)、技术兼容包(TCK)。JCP维护的规范包括J2ME、J2SE、J2EE，XML，OSS，JAIN等。组织成员可以提交JCR(Java SpECification RequESts)，通过特定程序以后，进入到下一版本的规范里面。

　　Google Web Toolkit(最早发布于2006年5月)

　　注：GWT(Google Web Toolkit) 是 Google 推出的一个开发 Ajax 应用的框架，它支持用 Java 开发和调试 Ajax 应用。

　　Groovy(最早发布于2004年5月)

　　注：Groovy是一种面向对象的程序设计语言，作为Java程序设计语言的一种可选替代品，并增加了Python，Ruby和Smalltalk中的一些特性。

　　云雾计算(用于虚拟服务器的设计理念，或无需EJB的分布式计算)

　　注：“云雾计算”的英文即Cloud Computing。自谷歌发展起来之后，极大规模的服务器集中在一起，统一管理，形成了“云雾计算”(“Cloud Computing”)的物质基础。“云雾计算”是社会计算能力的大集中，也是所谓“SaaS”的客观基础。

　　有趣的是，其中有几种技术已经成熟，或者说是“老”了，并且正在其被推荐应用的项目中有成熟的应用。当然，这五种技术都很有价值。OSGi是Eclipse的建模系统，Goovry因其正式的规范说明和频繁的改进版发布赢得支持。GWT也算是成熟稳定，云雾计算正在受到更为广泛市场的接受。

　　JRC和云雾计算是最近才被广泛接受的技术，但是厂商正在利用竞争和商业关系猎取支持来发布相关的产品(比如GridGain，Gigaspaces，和Terracotta)，而有的厂商还正在对此进行策划(TSS计划在TSSJS2008发布JCR相关的声明)。

　　这是一份很有趣的列表。你认为应该在2008学习哪几种Java技术呢?哪些技术现在正在展露头角并成为你以后学习的方向呢?(http://developer.e800.com.cn/articles/2008/87/1218074549696_1.html)
