SSH整合中碰到的问题

使用的版本为:struts2.1.8+hibernate3.2+spring2.5
applicationContext.xml配置如下:
<bean id="dao" class="com.xwx.dao.UserService">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
<bean id="userAction" class="com.xwx.action.UserAction">
<property name="us" ref="dao"/>
</bean>struts.xml配置如下:
<constant name="struts.objectFactory" value="org.apache.struts2.spring.StrutsSpringObjectFactory" />    <package name="user" namespace="/" extends="struts-default">
        <action name="userAction" class="userAction" >
         <result>/ok.jsp</result>
        </action>
    </package>页面代码如下:
  <s:form action="userAction" method="post">
   <s:textfield name="u.name" label="name"/><br/>
   <s:textfield name="u.password" label="password"/><br/>
   <s:submit/>
  </s:form>
其它的userAction与dao层就不贴了，没意义启动正常，页面正常显示，表单提交时，出现如下错误

  1.   

       你看一下你那个userAction写的估计有问题。。 特别是哪个报错的namespace
      

  2.   

    没有找到userAction，lz看看自己是否写错了，一般struts与spring结合class都是action类的第一个字母小写即可。
    还要在struts中加入这一句即可
    struts.objectFactory=spring
      

  3.   

    <constant name="struts.objectFactory" value="spring" />
    试试
      

  4.   

    struts2中的 form提交方式是你 写的那样吗？userAction
