SpringBoot 整合Shiro框架
Shiro
什么是Shiro?
●Apache Shiro是一个Java 的安全(权限)框架。
●Shiro可以非常容易的开发出足够好的应用，其不仅可以用在JavaSE环境，也可以用在JavaEE环境。
●Shiro可以完成，认证，授权，加密，会话管理，Web集成，缓存等.
●下载地址: http://shiro.apache.org/
有哪些功能
●Authentication: 身份认证、登录，验证用户是不是拥有相应的身份;
●Authorization:授权,即权限验证，验证某个已认证的用户是否拥有某个权限，即判断用户能否进行什么操作，如:验证某个用户是否拥有某个角色，或者细粒度的验证某个用户对某个资源是否具有某个权限!
●Session Manager: 会话管理，即用户登录后就是第-次会话，在没有退出之前，它的所有信息都在会话中;会话可以是普通的JavaSE环境，也可以是Web环境;
●Cryptography: 加密,保护数据的安全性，如密码加密存储到数据库中，而不是明文存储;
●Web Support: Web支持，可以非常容易的集成到Web环境;
●Caching: 缓存，比如用户登录后，其用户信息，拥有的角色、权限不必每次去查,这样可以提高效率
●Concurrency: Shiro支持多线程应用的并发验证，即，如在-个线程中开启另-一个线程,能把权限自动的传
播过去
●Testing:提供测试支持;
●RunAs:允许一个用户假装为另-一个用户(如果他们允许)的身份进行访问;
●Remember Me:记住我，这个是非常常见的功能，即一-次登录后， 下次再来的话不用登录了
Shiro架构(外部)
从外部来看Shiro,即从应用程序角度来观察如何使用shiro完成工作:
●subject: 应用代码直接交互的对象是Subject, 也就是说Shiro的对外API核心就是Subject, Subject代表了当前的用户，这个用户不-定是一个具体的人，与当前应用交互的任何东西都是Subject,如网络爬虫，机器人等，与Subject的所有交互都会委托给SecurityManager; Subject其实是一一个门面， SecurityManageer 才是
实际的执行者
●SecurityManager: 安全管理器，即所有与安全有关的操作都会与SercurityManager交互, 并且它管理着所有的Subject,可以看出它是Shiro的核心，它负责与Shiro的其他组件进行交互，它相当于SpringMVC的DispatcherServlet的角色
●Realm: Shiro从Realm获取安全数据 (如用户,角色，权限)，就是说SecurityManager要验证用户身份，那么它需要从Realm获取相应的用户进行比较，来确定用户的身份是否合法;也需要从Realm得到用户相应的角色、权限，进行验证用户的操作是否能够进行，可以把Realm看DataSource;
Shiro架构(内部)
●Subject: 任何可以与应用交互的用户;
●Security Manager:相当于SpringMVC中的DispatcherSerlet; 是Shiro的心脏， 所有具体的交互都通过Security Manager进行控制，它管理者所有的Subject, 且负责进行认证,授权，会话，及缓存的管理。
●Authenticator:负责Subject认证， 是-一个扩展点，可以自定义实现;可以使用认证策略(Authentication Strategy)，即什么情况下算用户认证通过了;
●Authorizer:授权器，即访问控制器，用来决定主体是否有权限进行相应的操作;即控制着用户能访问应用中
的那些功能;
●Realm: 可以有-一个或者多个的realm, 可以认为是安全实体数据源，即用于获取安全实体的，可以用JDBC实现，也可以是内存实现等等，由用户提供;所以- -般在应用中都需要实现自己的realm
●SessionManager:管理Session生 命周期的组件,而Shiro并不仅仅可以用在Web环境，也可以用在普通的JavaSE环境中
●CacheManager: 缓存控制器，来管理如用户，角色，权限等缓存的;因为这些数据基本上很少改变,放到缓存中后可以提高访问的性能;
●Cryptography:密码模块，Shiro 提高了一些常见的加密组件用于密码加密， 解密等
Shiro快速开始
准备工作
创建一个普通maven项目springboot-08-shiro,然后删除src目录,这样的话就可以在这个项目里新建很多model.
在springboot-08-shiro里新建model hello_shiro
