java代码实现通过consul获取微服务所在dataCente

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：

Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: org.glassfish.jersey.client.JerseyClientBuilder

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

  <dependency>
   <groupId>org.glassfish.jersey.core</groupId>
   <artifactId>jersey-client</artifactId>
   <version>2.17</version>
  </dependency>
