/*
* 1.LifecycleBeanPostProcessor,这是个DestructionAwareBeanPostProcessor的子类,负责org.
* apache.shiro.util.Initializable类型bean的生命周期的,初始化和销毁。主要是AuthorizingRealm类的子类,
* 以及EhCacheManager类。
* 2.HashedCredentialsMatcher,这个类是为了对密码进行编码的,防止密码在数据库里明码保存,当然在登陆认证的生活,
* 这个类也负责对form里输入的密码进行编码。
* 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。
