eleasticsearch运行时错误 - 传输层上捕获的异常 - java.nio.channels.UnresolvedAddressException

我目前正在构建一个可以获得弹性搜索结果列表的系统，但是我在servicemix中遇到一个重复出错的错误（它发生在30-60秒左右），这个错误是连接失败的 . 我如何阻止这种情况发生？注意运行ElasticSearch 1.7.1：

这是我认为引起问题的代码，因为它是连接到我的弹性服务器的代码 .

• 查询只返回所有内容

• ImmutableSettings仅包含{"name" => "elk"}

• InetSocketTransportAddress通常使用localhost：9300（但是我也测试了错误的地址） .

public static SearchResponse getElkResponse(InetSocketTransportAddress elkHost, HashMap<String, String> settingsMap, QueryBuilder query, int minTimeRange) {
    Settings settings = ImmutableSettings.settingsBuilder()
            .put(settingsMap)
            .build();


    TransportClient client = new TransportClient(settings).addTransportAddress(elkHost);
    client.admin().indices().prepareRefresh().execute().actionGet(); //not sure why this is need?
    SearchRequestBuilder req = client.prepareSearch()
            .setTimeout(TimeValue.timeValueMinutes(1))
            .addSort("@timestamp", SortOrder.ASC)
            .setQuery(query)
            .setPostFilter(FilterBuilders.rangeFilter("@timestamp").from("now-" + minTimeRange + "m").to("now"))
            .setSize(100);
    SearchResponse res = req.execute().actionGet();
    return res;
}
