Config

spring:

server:
  port: 8070
#  servlet:
#    context-path: /zuul

# eureka 注册中心配置
eureka:

# 指定路由规则
zuul:
  routes:
#    api-a:

#简写
    ratel-microservice-order: #微服务名字
      path: /order/** #匹配规则
#  ignored-services: ratel-microservice-order #忽略掉这个微服务，否则url以 /ratel-microservice-order 为前缀的也会访问 order 服务

进阶配置

请求转发

# 指定路由规则
# 匹配优先级 按配置先后循序
zuul:
  routes:
    api-foward: #微服务名字 或 url 前缀
      path: forward:/test #表示将匹配上的 请求转发到当前网关的接口上
