Parsing Elasticsearch无法使用自定义格式分析日期

根据文档（），应该可以使用Joda时间兼容的日期模式解析日期

我的数据包含如下日期：“2015-02-09 02:10:05245”

可以使用以下模式使用Joda time解析这些数据：“yyyy-MM-dd-HH:MM:ss，SSS”

但是，当我告诉索引使用此模式解析日期时，将数据加载到Elasticsearch失败，出现以下错误：

在索引模板中，“mydate”的指定方式如下：

{
  "template": "te*",
  "mappings": {
    "_default_" : {
      "properties": {
        "mydate": {
          "index": "analyzed",
          "type": "date",
          "format": "yyyy-MM-dd HH:mm:ss,SSS"
        }
      }
    }
  }
}

应该可以了，对吧？

这对我来说在ES 1.4.4上很有用

PUT hilden1

PUT hilden1/type1/_mapping
{
  "properties": {
    "dt": {"type": "date", "format": "yyyy-MM-dd HH:mm:ss,SSS"}
  }
}

POST hilden1/type1
{
  "dt": "2015-02-09 02:10:05,245"
}

GET hilden1/type1/_search

我真的不知道为什么，但我现在有工作要做。我注意到您显式地创建了一个类型“type1”，我依赖于默认值。我更改了索引，将默认值替换为type1，并告诉logstash使用type1作为索引类型。现在它可以工作了。你很可能在一个索引中有很多类型，所以最好的做法是调用它们来帮助我找到我的错误。我的映射声明了错误的

类型

，因此elasticsearch无法映射指定的日期格式。使用正确的类型名称为我解决了问题。
