Answer 1

如果你导入这包Struts-spring-plugin-2.2.1还报错，则你可以<package name="default" extends="struts-default">修改成：
<package name="login" extends="struts-default">

Answer 2

这个是应该是因为在struts.xml中的配置出了问题，你不妨把package中的extends属性值配上，例如：<package name="user" extends="struts-default">。

Answer 3

少了一个Struts-spring-plugin-2.2.1包

Answer 4

我也不太清楚

Answer 5

没有加载上freemark!

追问

不是呢，包都加了。我实在是没有办法了。问题是我上午运行好着，下午就不行了，而且那个类明明存在，硬说找不到！
