为了实现表示唯一访问者指标总数的日期直方图，查询 Elasticsearch 的最佳方法是什么？

考虑以下数据：

PUT /events
{
"mappings" : {
        "_doc" : {
            "properties" : {
                "userId" : { "type" : "keyword" },
                "eventDate" : { "type" : "date" }
            }
        }
    }
}

POST /events/_bulk
{ "index" : { "_index" : "events", "_type" : "_doc", "_id" : "1" } }
{"userId": "1","eventDate": "2019-03-04T13:40:18.514Z"}
{ "index" : { "_index" : "events", "_type" : "_doc", "_id" : "2" } }
{"userId": "2","eventDate": "2019-03-04T13:46:18.514Z"}
{ "index" : { "_index" : "events", "_type" …

我正在尝试为Exchange Web服务编写自定义Java客户端.我已经使用生成的客户端存根wsimport工具,说明在这里从EWS的Services.wsdl文件.现在我编写了使用这些存根的代码.我得到以下异常:

Exception in thread "main" com.sun.xml.internal.ws.wsdl.parser.InaccessibleWSDLException: 2   counts of InaccessibleWSDLException.

我们在上面看到的ExchangeDevelopmentTest是一个使用另一个类的客户端,而另一个类 …
