请有人帮忙。我两周以来一直在尝试这个。

答案 0 :(得分：0)

错误消息确切地说明了什么是错的。

您的配置文件为您的操作类使用一个包，您的操作类在另一个包中。

您的下一个问题是找不到结果，因为配置文件使用所有大写结果名称，而常量值都是小写的。

你也在使用旧的过滤器。为什么验证逻辑重复？

答案 1 :(得分：0)

struts.xml文件应放在

中

无论

1）在Java资源中 - ＆gt; src文件夹 - ＆gt; struts.xml。

OR

2）在WebContent中 - ＆gt; WEB-INF - ＆gt;类（创建一个名为＆＃34的新文件夹;类＆＃34;） - ＆gt; struts.xml中
