昨晚在做一个 Elasticsearch Demo 的时候，发现了这个错误，纠结了一小会，我的 Demo 是爬虫随便爬取了一些网站的信息，然后通过 Elasticsearch 去存储，结果发现其中一个字段，Mapping定义的类型是objcet，因为是个Array，而 Mapping 又定义不了Array ，所以定义了一个object 类型。结果创建 Mapping 成功了，但是添加数据失败了。

}添加数据的时候报错：
failure in bulk execution:
[0]: index [site_index1], type [site_type1], id [https://www.sojson.com], message [MapperParsingException[object mapping for [image] tried to parse field [null] as object, but found a concrete value]]已经说的很清楚了，就是Mapping 和存储的数据类型对不上。
"image": {
"type": "object"
}我开始排查存储的值有没有null 值，发现没有，都是有值了。
其实当报这样的错。有一个最简单的排查方式，就是不创建mapping ，然后直接创建索引，你看看自适应的mapping ，这个field 是什么类型。那么你创建就是什么类型。
我用自适应类型，发现这个数组的是string 类型，那么我就把它定义为string ，就解决错误了。
