Spring-Cloud-Gateway
本博客主要是搭建一个gateway的demo，记录了自己踩过的各种坑
项目目录 ：
gateway-service中的依赖：
注意此处不可添加spring-boot-starter-web的依赖，否则会报错。gateway是用过webflux实现 ，和spring MVC有冲突

discovery: #是否与服务发现组件进行结合，通过 serviceId(必须设置成大写) 转发到具体的服务实例。默认为false，设为true便开启通过服务中心的自动根据 serviceId 创建路由的功能。
locator:
enabled: true #路由访问方式：http://Gateway_HOST:Gateway_PORT/大写的serviceId/**，其中微服务应用名默认大写访问。
