我使用的是spring boot版本2.1.8.release，我遇到了以下问题：
你有解决办法吗？

这是我的测试，我用的是Windows10之类的操作系统，这是我的测试，

import org.I0Itec.zkclient.ZkClient;
import org.junit.Test;

import kafka.utils.ZKStringSerializer$;
import kafka.utils.ZkUtils;
import kafka.zk.EmbeddedZookeeper;

public class BaseTest {

private static final String ZKHOST = "127.0.0.1";

@Test
public void producerTest(){

    // setup Zookeeper
    EmbeddedZookeeper zkServer = new EmbeddedZookeeper();
    String zkConnect = ZKHOST + ":" + zkServer.port();
    ZkClient zkClient = new ZkClient(zkConnect, 30000, 30000, ZKStringSerializer$.MODULE$);
    ZkUtils zkUtils = ZkUtils.apply(zkClient, false);

    zkClient.close();
    zkServer.shutdown();
}
}
