这是我的代码：

 public class CollectionSource{
        private OkHttpClient httpClient = new OkHttpClient();
    public boolean collectSourceData() {
        ExecutorService ex = Executors.newFixedThreadPool(10);
        logger.info("docker source is starting!");
        for (int i =1; i<=10; i++) {
            String url = dockerSourceUrl + "2018-01-01"+ "?pageNum=" + i 
                +"&pageSize=100";
            DockerSyncTask dst = new DockerSyncTask(url);
            ex.submit(dst);
        }

        ex.shutdown();
        try {
            ex.awaitTermination(1L, TimeUnit.DAYS);
        } catch (InterruptedException e) {
            logger.error("awaitTermination error", e);
            return false;
        }

        logger.info("docker data source synchronized over!");
        return true;
    }
}

这是任务，内部类：

class DockerSyncTask implements Runnable {
    private String url;
    DockerSyncTask(String url) {
        this.url = url;
    }
    public void run() {
        Request request = new 
        Request.Builder().url(url).get().build();
        try {
            Response resp = httpClient.newCall(request).execute();

            if (!resp.isSuccessful()) {
                logger.warn("QuerySourceDataTask error with message:
                {}", resp.message());
            }

            String response = resp.body().string();
            if (response != null && !response.equalsIgnoreCase("")) {
                logger.debug("{} return:{}", url, response);
                //保存到DB
                savePageData(response);

            } else {
                logger.warn("QuerySourceDataTask return null with url:
                {}!", url);
            }
        } catch (IOException e) {
            logger.error("QuerySourceDataTask error, url is [{}]", 
            url, e);
        }
    }
}

当没有使用ExecutorService时（只有一个主线程），没有异常，有什么建议吗？

使用JDK1.8，okhttp3

get java.net.SocketException：当使用带有多线程的
