想法
暴露一些端点，提供一些功能。
-
http-cache
-
RateLimiter
-
... ...
不是用网关，单体应用
拦截器处理，基于 redis 的 cache 时间或者 RateLimiter处理。
结构：serviceName:http-cache:/user/1?queryString If-Modified-Since 结构：serviceName:RateLimiter:/user/1 99
使用网关
将端点信息存储到 redis 里，供 网关使用。 结构：serviceName:http-cache:endpoint:/user/{id} 100s
结构：serviceName:RateLimiter:endpoint:/user/{id} 100/s
