  application:
    name: client

#eureka:
#  client:
#    service-url:
#      defaultZone: http://localhost:10000/eureka
eureka:

#定义一个serverList给我们做负载均衡
##格式{serviceId}:ribbon:listOfservers

        String ip = serviceInstance.getHost();
        int port = serviceInstance.getPort();
        return restTemplate.getForObject("http://"+ip+":"+port+"index",String.class,"")+port;
