Shiro
Shiro是一个安全框架,用于认证、授权和管理应用程序的安全性。它提供了一组易于使用的API和工具,可以帮助您轻松地添加安全性到您的应用程序中;保护应用程序的机密性、完整性和可用性。可以与各种应用程序集成,包括Web应用程序、RESTful服务和基于消息的应用程序等。使用Shiro,您可以轻松地实现身份验证、权限控制、密码加密等功能,以确保您的应用程序得到充分的安全保护;
Security 和 Shiro
Spring Security和Shiro都是用于应用程序安全的框架,它们都提供了认证、授权和安全管理等方面的功能,但它们在实现方式和设计哲学上有一些不同。
- 来源不同:Spring Security最初是Spring框架的一个子项目,而Shiro是从Apache的一个开源项目而来
- 架构不同:Spring Security的设计哲学是将安全性集成到应用程序的架构中,这意味着Spring Security在许多方面都与Spring框架紧密耦合。而Shiro的设计哲学是通过简单的API和注解来实现安全性,使它可以与各种框架和技术集成
- 功能不同:尽管Spring Security和Shiro都提供了基本的认证和授权功能,但它们的实现方式和可定制性略有不同。Spring Security具有更多的配置选项和扩展性,而Shiro则更加简单易用,但可能在某些方面缺少灵活性
- 社区支持不同:由于Spring Security是Spring框架的一部分,因此它拥有强大的社区支持和生态系统。而Shiro虽然也有不错的社区支持,但在某些方面可能不如Spring Security流行
综上所述,选择Spring Security还是Shiro取决于您的具体需求和技术偏好。如果您已经使用了Spring框架,那么Spring Security可能是更好的选择。如果您需要一个更加简单易用的框架,并且需要与各种技术集成,那么Shiro可能更适合您的需求
Authentication:保证只有具有权限的用户才能访问系统中的特定资源,比如用户名/密码、敏感资源等。这样可以保护系统的安全性,防止未经授权的用户访问重要信息;
Authorization:作用在于根据用户提供的身份凭证,生成权限实体,并为之授予相应的权限;
Session Management:会话管理,Session 管理的作用主要是在网站浏览时保存用户的会话状态,当用户关闭浏览器时自动关闭会话,从而避免数据泄露;
Cryptography:加密,保护数据的安全性,如密码加密存储到数据库,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,即如在一个线程中开启另一个线程,能把权限自动传播过去;
Testing:提供测试支持;
Run As: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,通过session缓存数据
Subject(主体) :Shiro 框架中的一个核心概念获取当前登录的用户名和角色,验证当前用户的权限,提供当前用户信息,包括用户名、角色、权限等信息
SecurityManager(核心安全管理器): 是一个安全管理器,主要对账号、权限及身份认证进行设置和管理。它可以对 Spark 的部署模式进行配置,开放指定的权限,没有配置的权限就认为不具备相应的权限,这个安全管理器默认情况下是关闭的,需要手动去开启
Realm(领域) : Shiro 框架中用于保护应用程序中的数据安全的一种数据库;当用户执行认证(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。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。Realm 能做的工作主要有以下几个方面:
- 身份验证:验证账户和密码,并返回相关信息
- 权限获取:获取指定身份的权限,并返回相关信息
- 令牌支持:判断该令牌(Token)是否被支持
- 令牌有很多种类型,例如:HostAuthenticationToken(主机验证令牌),UsernamePasswordToken(账户密码验证令牌)
