（一）在pom.xml中添加依赖：

<dependency>
          <groupId>org.apache.shiro</groupId>
          <artifactId>shiro-core</artifactId>
          <version>${shiro.version}</version>

        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。*/

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

![Center 1][]
