struts2+spring配置后bean加载,bean为什么会初始化2次

下面是我的服务器出错情况:

我配置了一个UserActionBean,
<bean name="UserActionBean" class="com.test.modules.user.action.UserAction" singleton="false">
<property name="userHelper">
      <ref bean="UserHelperImplBean"/>
    </property>
  </bean>   
web.xml加载后UserActionBean初始化成功，可是到下面的action中要用时,就报找不到action了,检查了几天都没找到准确原因,大家认为可能是哪个环节出错了啊?
