简介
Security
是 Spring
家族中的一个安全管理框架。相比与另外一个安全框架Shiro
,它提供了更丰富的功能,社区资源也比Shiro丰富。
具体介绍和入门看springSecurity入门
原理初探
在实现之前幺要了解一下登录校验的流程以及SpringSecurity
的原理以及认证流程
1、登录校验流程
2、 SpringSecurity完整流程SpringSecurity
的原理其实就是一个过滤器链,内部包含了提供各种功能的过滤器。这里我们可以看看入门案例中的过滤器。
图中只展示了核心过滤器,其它的非核心过滤器并没有在图中展示。
UsernamePasswordAuthenticationFilter:负责处理我们在登陆页面填写了用户名密码后的登陆请求。入门案例的认证工作主要有它负责。
ExceptionTranslationFilter:处理过滤器链中抛出的任何AccessDeniedException
和AuthenticationException
。
FilterSecurityInterceptor:负责权限校验的过滤器。
我们可以通过Debug
查看当前系统中SpringSecurity
过滤器链中有哪些过滤器及它们的顺序。
3、认证流程
概念速查:
-
Authentication
接口: 它的实现类,表示当前访问系统的用户,封装了用户相关信息。 -
AuthenticationManager
接口:定义了认证Authentication的方法 -
UserDetailsService
接口:加载用户特定数据的核心接口。里面定义了一个根据用户名查询用户信息的方法。 -
UserDetails
接口:提供核心用户信息。通过UserDetailsService
根据用户名获取处理的用户信息要封装成UserDetails
对象返回。然后将这些信息封装到Authentication
对象中。
实现思路
登录
①自定义登录接口
调用ProviderManager
的方法进行认证 如果认证通过生成jwt
把用户信息存入redis
中
②自定义UserDetailsService
在这个实现类中去查询数据库
校验:
①定义Jwt认证过滤器
获取token
解析token
获取其中的userid
从redis
中获取用户信息
存入SecurityContextHolder
这里我们主要是实现登录接口的功能
核心思想就是就是将认证流程
中的UserDetailsService
重写其loadUserByUsername
的方法,使其从数据库中查询数据,然后用自己的类(我这里是UserLogin
)实现UserDetails
,在loadUserByUsername
中返回UserLogin
登录接口实现
准备工作
添加依赖,添加工具类,创建数据库,编写配置文件
1、添加依赖
<!--redis依赖-->
<dependency>

可以使用一下方法进行加密,passwordEncoder
