    3.ShiroRealm，这是个自定义的认证类，继承自AuthorizingRealm，负责用户的认证和权限的处理，可以参考JdbcRealm的实现。
    4.EhCacheManager，缓存管理，用户登陆成功后，把用户信息和权限信息缓存起来，然后每次用户请求时，放入用户的session中，如果不设置这个bean，每个请求都会查询一次数据库。
    5.SecurityManager，权限管理，这个类组合了登陆，登出，权限，session的处理，是个比较重要的类。
    6.ShiroFilterFactoryBean，是个factorybean，为了生成ShiroFilter。它主要保持了三项数据，securityManager，filters，filterChainDefinitionManager。
    7.DefaultAdvisorAutoProxyCreator，Spring的一个bean，由Advisor决定对哪些类的方法进行AOP代理。
    8.AuthorizationAttributeSourceAdvisor，shiro里实现的Advisor类，内部使用AopAllianceAnnotationsAuthorizingMethodInterceptor来拦截用以下注解的方法。*/

ehcache-shiro.xml内容：

<ehcache updateCheck="false" name="shiroCache">
    <!--
       name:缓存名称。
       maxElementsInMemory:缓存最大数目
       maxElementsOnDisk：硬盘最大缓存个数。
       eternal:对象是否永久有效，一但设置了，timeout将不起作用。
       overflowToDisk:是否保存到磁盘，当系统当机时
       timeToIdleSeconds:设置对象在失效前的允许闲置时间（单位：秒）。仅当eternal=false对象不是永久有效时使用，可选属性，默认值是0，也就是可闲置时间无穷大。
       timeToLiveSeconds:设置对象在失效前允许存活时间（单位：秒）。最大时间介于创建时间和失效时间之间。仅当eternal=false对象不是永久有效时使用，默认是0.，也就是对象存活时间无穷大。
       diskPersistent：是否缓存虚拟机重启期数据 Whether the disk store persists between restarts of the Virtual Machine. The default value is false.
       diskSpoolBufferSizeMB：这个参数设置DiskStore（磁盘缓存）的缓存区大小。默认是30MB。每个Cache都应该有自己的一个缓冲区。
       diskExpiryThreadIntervalSeconds：磁盘失效线程运行时间间隔，默认是120秒。
       memoryStoreEvictionPolicy：当达到maxElementsInMemory限制时，Ehcache将会根据指定的策略去清理内存。默认策略是LRU（最近最少使用）。你可以设置为FIFO（先进先出）或是LFU（较少使用）。
        clearOnFlush：内存数量最大时是否清除。
         memoryStoreEvictionPolicy:
            Ehcache的三种清空策略;
            FIFO，first in first out，这个是大家最熟的，先进先出。
            LFU， Less Frequently Used，就是上面例子中使用的策略，直白一点就是讲一直以来最少被使用的。如上面所讲，缓存的元素有一个hit属性，hit值最小的将会被清出缓存。
            LRU，Least Recently Used，最近最少使用的，缓存的元素有一个时间戳，当缓存容量满了，而又需要腾出地方来缓存新的元素的时候，那么现有缓存元素中时间戳离当前时间最远的元素将被清出缓存。

启动后在页面上输入：http://localhost:8080/boot/会跳转到login登录页面：

登录后会跳转到welcome页面，该页面使用了shiro标签，会进行权限认证：
