Shiro配置错误之“Error creating bean with name ‘shiroFilter’ defined in class path resource”
引子 ：
登录验证使用的是Shiro框架，由于新手，遇到很多问题。在配置过程中遇到“Error creating bean with name 'shiroFilter' defined in class path resource”这种错误，也百度了很多资料，后来陆续该了些东西，最后想到要记录些东西，以备后续自己能用到。所以错误日志也就是解决之前赋值保留的。
错误日志：

解决：找了将近两个小时、返现是自己之前将项目包路径进行了一些改变、导致无法加载自定义Bean CustomRealm 所致
