ssh简单问题，请教各位

     先发代码：
   web.xml:
  
  <listener>
     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
   classpath:applicationContext.xml
</param-value>
</context-param>applicationContext.xml:  <bean name="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocation"
value="classpath:hibernate.cfg.xml">
</property>
</bean>
<bean name="testDao" class="com.lxf.dao.TestDao">
    <property name="sessionFactory">
      <ref bean="sessionFactory"/>
    </property>
</bean>
<bean name="/test" class="com.lxf.struts.action.TestAction">
   <property name="testDao">
      <ref bean="testDao"/>
   </property>
</bean>
struts-config:    <plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
        <set-property property="contextConfigLocation" 
            value="/WEB-INF/applicationContext.xml"/>
  </plug-in>
  
TestAction:      TestDao testDao;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
TestForm testForm = (TestForm) form;// TODO Auto-generated method stub
System.out.println(testDao);
testDao.getAllBook();
return null;
}
public void setTestDao(TestDao testDao) {
this.testDao = testDao;
}
public TestDao getTestDao() {
return testDao;
}
  对于大家来说这代码应该很简单了，现在我的问题是在TestAction里面testDao为空，不知道哪里错了或者漏写了什么，请大家指正下     我以为是没有读到applicationContext.xml 所以我在两个地方写了，tomcat启动也没报错
