简介

SecuritySpring 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
Spring-Security实现登录接口_第1张图片

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。
Spring-Security实现登录接口_第2张图片
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AccessDeniedExceptionAuthenticationException

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
Spring-Security实现登录接口_第4张图片
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

​ 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

UserMapper

启动类

package com.zzuli;

import org.apache.ibatis.annotations.Mapper;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@MapperScan("com.zzuli.mapper")  //mapper扫描器
public class AppleunlockManageApplication {

    public static void main(String[] args) {
        SpringApplication.run(AppleunlockManageApplication.class, args);
    }

}

效果展示

注意:测试时要打开redis,数据库中的密码必须是加密后的
可以使用一下方法进行加密,passwordEncoderSecurityConfig中已经注入的

   @Resource
    private PasswordEncoder passwordEncoder;
	String encode = passwordEncoder.encode("123456");
    System.out.println(encode);
