#自定义路由映射
#order-service是订单服务的名称，访问路径为
#旧：  http://localhost:9000/order-serice/api/v1/order/find
#新:  http://localhost:9000/apigateway/order/api/v1/order/find
zuul:
 routes:
#方法一：
#  product-service: /apigateway/product/**
#  order-service: /apigateway/order/**
#方法二:
  product-route:    #路由名称，可以任意取
   service-id: product-service
   path: /apigateway/product/**
  order-route:
   service-id: order-service
   path: /apigateway/order/**
#忽略整个服务，不对外提供接口
#多个服务用逗号隔开product-service,order-service
#即不能用http://localhost:9000/order-serice/api/v1/order/find方式访问
 # ignored-services: product-service
#正则表达式忽略多个服务

#zuul使用Ribbon负载均衡,所以要配置ribbon超时时间,否则很短
 host:
  connect-timeout-millis: 15000 #HTTP连接超时要比Hystrix的大
  socket-timeout-millis: 60000  #socket超时
ribbon:
 ReadTimeout: 10000
 ConnectTimeout: 10000
