does not contain handler parameter named 'method' 异常

jsp文件中有一个form，

<form action="wapAddressAction.do?method=saveSelect" >

</form>

点击提交按钮，提示异常：

org.apache.catalina.core.StandardWrapperValve invoke
严重: Servlet.service() for servlet action threw exception
javax.servlet.ServletException: Request[/wap/wapAddressAction] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.

解决办法：

最后在form里面加了一个 method="post"就可以了
