遇到的问题：

请求接口http://localhost:8040/user/123 正常应该被zuul网关转发到microservice-provider-user服务的接口中但是测试过程中一直出现

com.netflix.client.ClientException: Load balancer does not have available server for client

 原因：zuul网关服务microservice-gateway-zuul 的健康检查服务没开启，

	org.springframework.boot
	spring-boot-starter-actuator

spring.cloud.consul.heartbeat.enabled = true

spring.cloud.consul.healthCheckPath = /health 

spring.cloud.consul.healthCheckInterval = 15s
