安全、Spring Security
Spring Security是针对Spring项目的安全框架,也是Spring Boot底层安全模 块默认的技术选型。他可以实现强大的web安全控制。对于安全控制,我们仅 需引入spring-boot-starter-security模块,进行少量的配置,即可实现强大的 安全管理。
几个类:
WebSecurityConfigurerAdapter:自定义Security策略 AuthenticationManagerBuilder:自定义认证策略
@EnableWebSecurity:开启WebSecurity模式

一个西瓜圆又圆 劈它一刀成两半 你一半来 给你你不要 给他他不收 那就不给 把两人撵走 他们不走你走 走啦,一挥手,伤自尊
不买西瓜别缠我,缓慢纠缠様 两人缠我赖皮,手慢动作左右挥动 看我厉害,转头缓步拍苍蝇状 拍死了,手抱西瓜状+奥特曼十字手+广播操准备运动的站立
