这里有些奇怪（尽管它可能不是问题的唯一原因）：

在你的 struts 配置文件中，你已经定义了

<action attribute="adminUserCreationForm" .....
            type="Admin.Action.AdminUserCreationAction">

这意味着应该在 Admin.Action 包下找到类 AdminUserCreationAction。

但是，您的 AdminUserCreationAction 类在 Admin.Form 包下声明：

package Admin.Form;
public class AdminUserCreationForm ...

请尝试在这两种情况下使用相同的包名。
