SpringCloud学习（五）：Zuul 路由过滤/网关

菜鸟学渣接触spring cloud 系列...

公司也上微服务了，再不学习下就凉了，所以来踩坑吧...

版本：

　　spring-boot: 2.0

　　spring-cloud: Finchley.SR1

已有项目：

　　[eureka-server] # 注册中心 port 8761

　　[eureka-client-one] # 微服务1 port 8501

　　[eureka-client-two] # 微服务2 port 8502

　　[eureka-client-turbine] # 断路监控 port 8503

能上图绝不BB：

　　 SpringCloud学习（五）：Zuul 路由过滤/网关

　　添加网关后，所有微服务API都通过ZUUL访问，zuul根据url分发到各个微服务实例

　　spring-cloud-gateway是Spring自己撸的网关，和netflx-zuul性质一样，后面也去学习一下.

一、Zuul网关 [eureka-client-zuul]

　　新建项目[eureka-client-zuul]

　　引入依赖 spring-cloud-starter-netflix-zuul
