satoken springboot3

1、Sa-Token 介绍

1.1 Sa-Token 开发文档：https://sa-token.cc

1.2 Sa-Token 是一个轻量级 Java 权限认证框架，主要解决：登录认证、权限认证、单点登录、OAuth2.0、微服务鉴权等一系列权限相关问题。

2.2 yml 配置 sa-token


server:
  port: 8080
 
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/xxx

  data:
    redis:
      database: 1
 
sa-token:
  token-name: X-Token
  # token有效期，单位s 默认30天, -1代表永不过期
  timeout: -1
  # token 最低活跃频率（单位：秒），如果 token 超过此时间没有访问系统就会被冻结，默认-1 代表不限制，永不冻结
  active-timeout: 3600
