struct中action-mappings/action可以拥有set-property子标签，这里描述它的用法。

要使用action-mappings/action/set-property，需要编写ActionMapping子类，并给action-mappings 标签加上type属性，属性值就是我们编写的字类。这样当action的execute享有客户操作时将得到我们编写的ActionMapping事例。

我们编写的ActionMapping要具有action-mappings/action/set-property所设置的所有属性。如果action-mappings/action拥有set-property子标签，那么execute方法获得的ActionMapping事例就拥有set-property所设置的属性值。

例:

1.struts_config.xml

<action-mappings type="testActionMapping">
    <action name="loginActionForm" path="/login" scope="request" type="testAction">
      <set-property property="name" value="larrin" />
     </action>
<action-mappings>

2.testActionMapping

   public testActionMapping extends ActionMapping
   {
      ....
      private String name;
      String getName(){return name;}
      void setName(String val){name = val;}
      ...
   }

3.testAction
   public testAction extends Action
   {
     public ActionForward execute(ActionMapping actionMapping,
                                                           ActionForm actionForm,
                                                           HttpServletRequest httpServletRequest,
                                                           HttpServletResponse httpServletResponse)
     {
         testActionMapping testForm = (testActionMapping )actionForm;
         String name = testForm.getName();
     }
   }
