推荐答案
最后我找到了解决方案，将 .action 添加到 action 值后.
Finally i found the solution is that , after adding .action to the action value.
一切正常.
<s:form action="invoke.action">
<s:textfield name="name" label="UserName"></s:textfield><br>
<s:password name="password" label="Password"></s:password><br>
<s:submit value="GO"></s:submit>
