Spring Security 6 step by step

Spring Security Basics

为什么使用Spring Security

1. Spring Security由Spring的一个团队构建，该团队擅长安全性，并考虑了所有安全场景。使用SpringSecurity，我们可以用最少的配置保护web应用。所以这里没有必要重新发明轮子。
2. Spring Security处理常见的安全漏洞，如CSRE、COR等。对于发现的任何安全漏洞，框架将在许多组织使用时立即修补
3. 使用SpringSecurity，我们可以以最少的配置轻松地保护页面/API路径、强制角色、方法级安全等。同时Spring Security支持各种安全标准来实现身份验证，例如使用用户名/密码身份验证、JWT令牌、OAuthe、OpenID等。
