在s:form里加上你的namespace即可. 
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> 

 

打开login.jsp的时候，控制台老是输出,但是不影响使用: 

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. 

 

后将 login.jsp 

  <s:form action="/page/hello"> 

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

问题解决!
