struts1 配制文件<set-property/>

       <action name="Test" path="/logon" type="com.sve.Logon" validate="false" scope="request">
                        <set-property property="method" value="view"/>
                        <set-property property="permission" value="platform:common.page"/>
                        <set-property property="helpId" value="reporting.reportLandingPage"/>
                        <forward name="View" path="reporting"/>
        </action>
