警告: No configuration found for the specified action: 'hello' in namespace:
struts.xml

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

<action name="hello" 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!
