ERROR ContextLoader:350 - Context initialization failed-优快云博客

博客讲述了在开发中遇到的问题，起初以为是com.lnx.oa.dao.IApplicationDao类名称有误，修改后仍出错。后来发现是com.lnx.oa.dao.Impl.ApplicationDaoImpl类缺少关键注释@Repository，导致Spring无法初始化该类，进而出现依赖注入错误。

一开始以为是com.lnx.oa.dao.IApplicationDao类的名称有误，但是改了之后还是有错，后来发现是com.lnx.oa.dao.Impl.ApplicationDaoImpl类中缺了关键
注释@Repository ，没有该注释，spring就不知道该怎么去初始化.IApplicationDao，所以会报依赖注入出错，找不到该类
