Shiro是Apache 的一个强大且易用的Java安全框架,执行身份验证、授权、暗码学和会话管理。Shiro 主要分为两个部分就是认证和授权两部分
一、介绍
- Subject代表了当前用户的安全操纵
- 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。
- Authenticator即认证器,对用户身份举行认证,Authenticator是一个接口,shiro提供ModularRealmAuthenticator实现类,通过ModularRealmAuthenticator基本上可以满足大多数需求,也可以自界说认证器。
- Authorizer即授权器,用户通过认证器认证通过,在访问功能时需要通过授权器判定用户是否有此功能的操纵权限。
- 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。
- sessionManager即会话管理,shiro框架界说了一套会话管理,它不依赖web容器的session,所以shiro可以使用在非web应用上。
Shiro相关类介绍
- (1)Authentication 认证 —— 用户登录
- (2)Authorization 授权 —- 用户具有哪些权限
- (3)Cryptography 安全数据加密
- (4)Session Management 会话管理
- (5)Web Integration web系统集成
- (6)Interations 集成其它应用,spring、缓存框架
