遇到了很奇怪的事情，项目里有个类A无论是在Spring，Struts中都没有被配置(已经反复确认了一下午了)
通过IDEA的Alt + F7 清除了其他类对该类的依赖，清除了该类的注解，直到Alt+F7找不到引用，等于说这个类A就是一个完全独立没有被任何引用的类，如下图
而且我还将类本身写了空类，事实上已经隔离了hibernate，spring和struts的配置也是保证启动的最小配置，不删除该类项目能正常启动，只要删了他，或者network包下的另外两个类，就会报相同的错，感觉就像赖着不走一样，但network包下的其他类，包括曾经有一个基类也能被正常删除
错误还不是一般的ClassNotFound这种错误，我也没见过这个错误，尝试过升级降级log4j、spring、struts的版本都不行
