修复 ElasticSearch 'No handler for type [int] declared on field ...'

问题：

你想在 ElasticSearch 中创建具有自定义映射的索引，但你看到类似这样的错误消息：

elasticsearch-error.txt

elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'No handler for type [int] declared on field [id]')

elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'No handler for type [int] declared on field [id]')

你的映射可能如下所示

mapping-bad.json

"id": {
    "type":  "int"
}

"id": {
    "type":  "int"
}

在你的映射 properties 中。

这里的问题是 int：ElasticSearch 使用 integer 作为整数类型，而不是 int！

为了修复此问题，将属性更改为

mapping-fixed.json

"id": {
    "type":  "integer"
}

"id": {
    "type":  "integer"
}

并重试创建索引。
