整合导入顺序：struts--->spring--->hibernate
加载原理：把struts的启动任务交给web.xml，然后spring的加载交给struts，
在粗体前后分别加入：
<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>
<message-resources parameter="com.handson.springlogin.struts.ApplicationResources" />
<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="classpath:applicationContext*.xml" />
</plug-in>
最后hibernate交给spring管理（导入时选择第二个）：
applicationContext-hibernate.xml
