spring-config-shiro.xml 在祖册securityManager，userRealm的 realm等等bean的时候找不到对应的文件，包名改了以后没改class的位置，用原来的包名搜索，替换成新的包名
ClassNotFoundException 异常 检查你的注解 和Bean扫描器
nested exception is java.lang.ClassNotFoundException: com.wamgxin.flow.core.security.shiro.cache.SpringCacheManagerWrapper
确定该路径下有这个类吗,还有xml里面的配置的包名.类名改了没有
ClassNotFoundException: com.wamgxin.flow.core.security.shiro.cache.SpringCacheManagerWrapper
at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:336)
首先你修改之后代码没问题，然后看运行抛出什么异常，根据你的异常信息，应该是没有注册进去你的bean没有注入的所以找不到该bean，也有可能是缓存的问题，你重新build一下项目 没准就好了。。。
在修改包名之前是好的，可以运行，不报错不抛异常，所以我觉得代码是没有问题的，问题出在修改了包名之后，某些地方不匹配了。不知道是不是这样，还望各位大佬指点
修改包名之后，路径会变，你检查下你的context.xml里面是不是配置了特定的路径。
说错了，你看下server.xml里面是不是有这种配置，删掉在试试。
