The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true.

# 一、前言 #

在创建es索引的时候，会遇到这样的错误：

创建语句：

PUT /griffin
    {
        "aliases": {},
        "mappings": {
          
            "_doc": {
                "properties": {
                    "name": {
                        "fields": {
                            "keyword": {
                                "ignore_above": 256,
                                "type": "keyword"
                            }
                        },
                        "type": "text"
                    },
                    "tmst": {
                        "type": "date"
                    }
                }
            }
        },
        "settings": {
            "index": {
                "number_of_replicas": "2",
                "number_of_shards": "5"
            }
        }
    }

{
      "error": {
        "root_cause": [
          {
            "type": "illegal_argument_exception",
            "reason": "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
          }
        ],
        "type": "illegal_argument_exception",
        "reason": "The mapping definition cannot be nested under a type [_doc] unless include_type_name is set to true."
      },
      "status": 400
    }

原因是：不能在type类型上创建映射 ， 在es7中已经在内部取消了， type。

# 二、解决方案 #

去掉 \_doc ， 就可以了

PUT /griffin
    {
        "aliases": {},
        "mappings": {
        
                "properties": {
                    "name": {
                        "fields": {
                            "keyword": {
                                "ignore_above": 256,
                                "type": "keyword"
                            }
                        },
                        "type": "text"
                    },
                    "tmst": {
                        "type": "date"
                    }
                }
        },
        "settings": {
            "index": {
                "number_of_replicas": "2",
                "number_of_shards": "5"
            }
        }
    }
