java代码实现通过consul获取微服务所在dataCenter

1. 用orbitz.consul client 端来获取
   代码如下：

package com.yj.consul.client.consulClient;

import com.orbitz.consul.AgentClient;
import com.orbitz.consul.Consul;

public class App 
{
    public static void main( String[] args )
    {
        Consul consul = Consul.builder().build();
        AgentClient agentClient = consul.agentClient();
        System.out.println(agentClient.getAgent().getConfig().getDatacenter());
    }
}

问题：

问题是，缺少org.glassfish.jersey.client.JerseyClientBuilder的包
pom文件中引入

  
   org.glassfish.jersey.core
   jersey-client
   2.17
