DispatchAction ServletException: Request does not contain handler parameter named 'method'
提问by DavidAdair
I have searched all over and am unable to find an answer to my issue. From what I know about DispatchAction's this code should be working fine. The stack trace is as follows. I am using Struts1.3 and Spring with tiles for layouts (Please excuse my code blocks I am pretty new to using stackoverflow) Please let me know if you need more information to help me. Thanks for your time.
我已经搜索了所有内容，但无法找到我的问题的答案。根据我对 DispatchAction 的了解，这段代码应该可以正常工作。堆栈跟踪如下。我正在使用 Struts1.3 和 Spring 和用于布局的瓷砖（请原谅我的代码块，我对使用 stackoverflow 还很陌生）如果您需要更多信息来帮助我，请告诉我。谢谢你的时间。
javax.servlet.ServletException: Request[/authorizeShipment] does not contain handler parameter named 'method'. This may be caused by whitespace in the label text.

The exception is raised because Struts cannot find a "method=xxxx" in HTTP request.
引发异常是因为 Struts 在 HTTP 请求中找不到“method=xxxx”。
I think you should change from
我认为你应该从
<html:submit parameter="method" value="deny">
to
到
<html:hidden parameter="method" value="deny"> or some other tags for hidden.
I mean, the "method=deny" should be looked as
我的意思是，“方法=拒绝”应该被视为
<input type="hidden" name="method" value="deny"/>
In your HTML pages generated from the JSP. Please check that.
在您从 JSP 生成的 HTML 页面中。请检查一下。
PS : You can use Browser Developer tool to check HTTP requests. All recent browsers can do that.
