第一课和第二课我们学习shiro的快速开始和spring-shiro的整合，这张我们学习shiro的验证和授权，以及盐值加密，第二realm，说起来学习，其实不过是粘贴代码罢了。
先来看目录结构，为了方便，java类都放在同一个包下面了

Shiro Core Components - Not Spring Specific
========================================================= -->
<!-- Shiro's main business-tier object for web-enabled applications
(use DefaultSecurityManager instead when there is no web environment)-->
<!-- 1.配置securityManager -->
<bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
<property name="cacheManager" ref="cacheManager"/>
<property name="authenticator" ref="authenticator"></property>
<!-- Single realm app. If you have multiple realms, use the 'realms' property instead. -->
<!-- <property name="sessionMode" value="native"/> -->
<!-- <property name="realm" ref="jdbcRealm"/> -->
<property name="realms">
<list>
<ref bean="jdbcRealm"/>
<ref bean="secondRealm"/>
</list>
</property>
<!-- 超时时间 -->
<property name="rememberMeManager.cookie.maxAge" value="10"></property>
</bean>
<!-- Let's use some enterprise caching support for better performance. You can replace this with any enterprise
caching framework implementation that you like (Terracotta+Ehcache, Coherence, GigaSpaces, etc -->
<!-- 2.配置cacheManager
2.1需要加入ehcache的jar包及配置文件
-->
<bean id="cacheManager" class="org.apache.shiro.cache.ehcache.EhCacheManager">
<!-- Set a net.sf.ehcache.CacheManager instance here if you already have one. If not, a new one
will be creaed with a default config:
<property name="cacheManager" ref="ehCacheManager"/> -->
<!-- If you don't have a pre-built net.sf.ehcache.CacheManager instance to inject, but you want
a specific Ehcache configuration to be used, specify that here. If you don't, a default

<!-- Used by the SecurityManager to access security data (users, roles, etc).
Many other realm implementations can be used too (PropertiesRealm,
LdapRealm, etc. -->

3.1直接配置实现了 org.apache.shiro.realm.Realm接口的bean

for Spring-configured Shiro objects so you don't have to
1) specify an init-method and destroy-method attributes for every bean
definition and
2) even know which Shiro objects require these methods to be
called. -->
<!-- 4.配置lifecycleBeanPostProcessor，可以自动的调用配置在spring ioc容器中shiro bean 的生命周期方法 -->

<!-- Enable Shiro Annotations for Spring-configured beans. Only run after
the lifecycleBeanProcessor has run: -->

web.xml uses the DelegatingFilterProxy to access this bean. This allows us
to wire things with more control as well utilize nice Spring things such as
PropertiesPlaceholderConfigurer and abstract beans or anything else we might need: -->
