在s:form里加上你的namespace便可. 
如 
<s:form namespace="/你的namespace" action="module"> ... </s:form>

struts.xml 

<package name="struts2" namespace="/page" extends="struts-default"> 

<action name="hello" class="com.str2.web.action.LoginAction"> 
<result name="re">/WEB-INF/page/test.jsp</result> 
<result name="log">/login.jsp</result> 
<result name="ok">/content.jsp</result> 
</action> 

</package> 


login.jsp 

  <s:form action="/page/hello"> 
  <s:textfield name="username" label="username"></s:textfield> 
  <s:password name="password" label="password"></s:password> 
  <s:submit/> 
  <s:reset/> 
  </s:form>

 

打開login.jsp的時候，控制檯總是輸出,可是不影響使用: 

警告: No configuration found for the specified action: 'hello' in namespace: ''. Form action defaulting to 'action' attribute's literal value.

警告: No configuration found for the specified action: 'hello' in namespace: ''. Form action defaulting to 'action' attribute's literal value.

 

後將 login.jsp 

  <s:form action="/page/hello"> 

改成 
  <s:form action="hello" namespace="/page"> 

問題解決!
