javax.servlet.ServletException: 请求[/平台] 不包含名为 'action' 的处理程序参数
javax.servlet.ServletException: Request[/platform] does not contain handler parameter named 'action'
我在开发 Struts 软件。软件 运行 正确，但是当我停留超过 5 分钟无所事事并点击加入另一个页面时，我收到错误 500 :
javax.servlet.ServletException: Request[/platform] does
not contain handler parameter named 'action'.
我和我的公司谈过，问题不可能出在服务器安全上。

您正在调用映射为 /platform 的操作，它需要一个名为 action 的参数。您应该将参数 action 添加到 URL.
<action attribute="platformForm" name="platformForm" path="/platform"
scope="request" parameter="action" type="fr.niji.struts.action.PlatformAction">
<forward name="list" path="/listPlatforms.jsp" />
<forward name="display" path="/displayPlatform.jsp" />
<forward name="change" path="/displayPlatform.jsp" />
</action>
千辛万苦后，我找到了解决办法。为了修改 URL，我继续我的 jsp 并修改标签 html:form。
例如，使用操作参数“添加”：
<html:form action="/platform.do?action=add" styleId="formPrincipale"> <html:hidden property="idPlatform" styleId="idPlatform"/> <html:hidden property="action" styleId="action" value="add"/>
