Request[/airSellOS] does not contain handler parameter named 'method'

bug：

javax.servlet.ServletException: Request[/airSellOS] does not contain handler parameter named 'method'.  This may be caused by whitespace in the label text.
 at org.apache.struts.actions.DispatchAction.unspecified(DispatchAction.java:224)
 at org.apache.struts.actions.DispatchAction.dispatchMethod(DispatchAction.java:258)

功能描述：

提交表单

<form action="<%=basePath%>airSellOS.do?method=user">

... ...

</form>

action airSellOS不对应任何的表单form

解决方案：

一、表单出加入属性“method="post"”

二、将action中method写入隐藏表单域中

      写法：<form action="<%=basePath%>airSellOS.do">

     <input type="hidden" name="method" value="user">
