本文探讨了Apache Shiro框架中Realm配置引发的UnresolveableReferenceException异常问题。通过一个具体的例子展示了错误信息，并深入分析了问题根源在于Realm实例名称大小写不匹配导致的引用错误。

代码：

#创建一个realm
MyRealm1=com.hongao.shiro.chapterOne.MyRealm1
#指定securityManager的realms实现
securityManager.realms=$myRealm1

原因：MyRealm1首字母大写了，与$myRealm1 不匹配

org.apache.shiro.config.UnresolveableReferenceException: The object with id [myRealm1] has not yet been defined and therefore cannot be referenced. Please ensure objects are defined in the order in which they should be created and made available for future reference.
