确保

struts config.xml

位于WEB-INF文件夹中。类似地，

hibernate.cfg.xml

也应该位于适当的位置（如果您正在使用它）。

您已将web应用程序配置为使用

struts config.xml

<init-param>
    <param-name>config</param-name>
    <param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>


配置
/WEB-INF/struts-config.xml

但指定文件夹中没有具有此名称的文件。确保该文件存在，或者如果对struts配置文件使用其他名称，则可以更改此init param值以反映文件可用性。如果每个模块有多个配置文件，可以使用逗号分隔名称

您需要从apache lib文件夹添加servlet-api.jar。您需要将struts.xml文件夹包含在java资源下的src文件夹中。

1）您提到的struts.xml文件名是config struts.xml，但在init参数中，您写的是struts config.xml。请正确核对姓名

2）或者（常见问题）是因为struts xml文件中缺少DTD标记。尝试将此代码添加到struts config.xml中的

标记上方

请分享您的软件包结构。您有没有找到解决此错误的方法？
