 /**
- * 缓存所有api，方便网关鉴权
+ * =====================================网关鉴权使用说明=======================================
+ * 场景：
+ *      微服务部署在内网，确定安全，无需在每个微服务都实现一次权限控制的逻辑，可以在网关层面实现统一鉴权
+ * 使用方式：
+ *      1、在每个微服务的配置文件中添加参数：security.aspect.enabled: false 关闭系统默认的通过注解方式鉴权，默认开启
+ *      2、在每个微服务的配置文件中添加参数：routePrefix: 值为网关中微服务匹配的路由地址，例如: /auth
+ *      3、在网关配置文件中添加参数：security.gateway.enabled: true 启用网关统一鉴权，默认关闭
+ *
+ * 通过反射扫描所有控制器，缓存所有控制器的映射路径以及对应的权限注解，缓存到redis，方便网关鉴权
