###配置zuul路由
zuul.routes.service-a.path= /service-a/**
zuul.routes.service-a.serviceId = client
#zuul.routes..service-b.path= /service-b/**
#zuul.routes.service-b.serviceId  = hystrix-master

###配置本地跳轉
##zuul.routes.hystrix-master.url= forward:/local

###關閉指定的過濾器
zuul.ZuulRequestFilter.pre.disable = true

#####指定url訪問
####zuul.routes.service-a.url= http://localhost:8080/service-a

####簡化配置爲zuul.routes.<serviceId> = <path>
####默認自動整合eureka的所有服務
###zuul.routes.hystrix-master = /hystrix-master/**

####忽略指定  service
#####zuul.ignored-services= *
####忽略指定pattern
####zuul.ignored-patterns = /**/getClientDelay/**

####路由前綴
#zuul.prefix = /hello    ###有bug 能access successful  not route found
####移除所有服務代理前綴
#zuul.strip-prefix=false
