SpringBoot 集成 SpringSecurity + MySQL + JWT 无太多理论，直接盘
一般用于Web管理系统
可以先看 SpringBoot SpringSecurity 基于内存的使用介绍
本文介绍如何整合 SpringSecurity + MySQL + JWT
数据结构
数据库脚本：https://gitee.com/VipSoft/VipBoot/blob/develop/vipsoft-security/sql/Security.sql
常规权限管理数据结构设计，三张常规表：用户、角色、菜单，通过用户和角色的关系，角色和菜单（权限）的关系，实现用户和菜单（按钮）的访问控制权
用户登录
- SecurityConfig 中添加登录接口匿名访问配置
.antMatchers("/auth/login", "/captchaImage").anonymous()BCryptPasswordEncoder密码加密方式 - POST 登录接口
/auth/login调用
AuthorizationController.login用户登录接口
做入参、图形验证码等验证。 - 实现
UserDetailsService接口根据用户名，去数据库获取用户信息、权限获取等
- 密码验证
AuthorizationService.login
调用authenticationManager.authenticate(authenticationToken)看密码是否正确
可以在此集合 Redis 做失败次数逻辑处理 - 通过JWT 生成 Token
调用
jwtUtil.generateToken(userId)生成Token令牌
将 用户信息放入 Redis
剔除其它已登录的用户（如果需要） - 返回Map对象给前端
接口权限认证
- 获取
request.getHeader中的token信息AuthenticationTokenFilter.doFilterInternal
解析 Token 中的用户ID 去 Redis 缓存中获取用户信息
将信息赋到SecurityContextHolder.getContext().setAuthentication(authenticationToken)中，供权限验证获取用户信息使用, SecurityContextHolder使用了ThreadLocal机制来保存每个使用者的安全上下文 - 接口权限配置
UserController类的方法上，加了@PreAuthorize("@ps.hasAnyPermi('system:user:list')")用来做权限控制 - 访问权限控制
PermissionService.hasAnyPermi判断，用户所拥有的权限，是否包含@PreAuthorize("@ps.hasAnyPermi('system:user:list')")中配置的权限，包含则有权访问
用户登录代码

private static final String PERMISSION_DELIMETER = ",";
/**
