Shiro简介

Apache Shiro是一个强大且易用的Java安全框架,执行身份验证、授权、密码和会话管理。使用Shiro的易于理解的API,您可以快速、轻松地获得任何应用程序,从最小的移动应用程序到最大的网络和企业应用程序。

  • Shiro是一个开源的java安全(权限)框架,它能够实现身份验证、授权、加密和会话管理等功能。
  • Shiro是apache旗下的产品,它的官网是: shiro官网: Apache Shiro
  • Shiro不仅可以用于javaEE环境,也可以用于javaSE

主要功能

  • Authentication:身份认证,验证用户是否拥有某个身份。
  • Authorization: 权限校验,验证某个已认证的用户是否拥有某个权限。确定“谁”可以访问“什么”
  • Session Management:会话管理,管理用户登录后的会话,
  • Cryptography:加密,使用密码学加密数据,如加密密码。
  • Web Support:Web支持,能够比较轻易地整合到Web环境中。
  • Caching:缓存,对用户的数据进行缓存,
  • Concurrency:并发,Apache Shiro支持具有并发功能的多线程应用程序,也就是说支持在多线程应用中并发验证
  • Testing:测试,提供了测试的支持。
  • Run as :允许用户以其他用户的身份来登录。
  • Remember me :记住我

三个核心组件:Subject, SecurityManager 和 Realms

Subject:即“当前操作用户”。但是,在Shiro中,Subject这一概念并不仅仅指人,也可以是第三方进程、后台帐户(Daemon Account)或其他类似事物。它仅仅意味着“当前跟软件交互的东西”。
  Subject代表了当前用户的安全操作,SecurityManager则管理所有用户的安全操作。
SecurityManager:它是Shiro框架的核心,典型的Facade模式,Shiro通过SecurityManager来管理内部组件实例,并通过它来提供安全管理的各种服务。
Realm: Realm充当了Shiro与应用安全数据间的“桥梁”或者“连接器”。也就是说,当对用户执行认证(登录)和授权(访问控制)验证时,Shiro会从应用配置的Realm中查找用户及其权限信息。
  从这个意义上讲,Realm实质上是一个安全相关的DAO:它封装了数据源的连接细节,并在需要时将相关数据提供给Shiro。当配置Shiro时,你必须至少指定一个Realm,用于认证和(或)授权。配置多个Realm是可以的,但是至少需要一个。
  Shiro内置了可以连接大量安全数据源(又名目录)的Realm,如LDAP、关系数据库(JDBC)、类似INI的文本配置资源以及属性文件等。如果缺省的Realm不能满足需求,你还可以插入代表自定义数据源的自己的Realm实现。
