struts.xml的文件如下，並將它與web.xml文件創建

請問您可以添加您的web.xml嗎？> – 2011-04-27 06:28:02

net.vanita.contact.view.ContactAction是否擴展org.apache.struts.actionAction？ – lobster1234 2011-04-27 08:04:50

公共類ContactAction擴展ActionSupport – user714698 2011-04-27 09:23:40

爲什麼你使用

<s:form action="/add" method="post">

在那裏你可以簡單地通過使用

<s:form action="add" method="post">

問題做到這一點的是，Struts2框架無法找到你的行動給定的命名空間。
