警告:No configuration found for the specified action

阅读更多

Struts2配置有命名空间的Action时,前台<s:form > 中需要加入命名空间属性 namespace,这个属性的值与struts2配置中的空间名要一至

<!--struts2配置-->
   
 <package name="admin" namespace="/admin"  extends="struts-default"> 

     <action name="myLogin" class="admin.action.LoginAction"> 

         <result name="input">/index.jsp</result> 

         <result name="success">/welcome.jsp</result> 

     </action> 

 </package> 
   

 <!--前台-->      

 <s:form  action="myLogin" method="post" namespace="/admin"  > 

 <s:textfield name="username" label="用户名"></s:textfield> 

 <s:textfield name="password" label="密码"></s:textfield> 

 <s:submit label="登录"></s:submit> 

 </s:form> 

 

如果你不是使用的struts2的标签,而是使用的传统的html代码,则表单的action属性必须加上完整的路径和后缀

也就是说,必须改成如下代码:

<form name="form" method="post" action="/admin/login.action">
