ElasticSearch 7.x 默认不在支持指定索引类型

在elasticsearch7.x上执行：
 

put es_test
{
    "settings":{    
    "number_of_shards" : 3,   
    "number_of_replicas" : 0    
    },    
     "mappings":{    
      "books":{     
        "properties":{        
            "title":{"type":"text"},
            "name":{"type":"text","index":false},
            "publish_date":{"type":"date","index":false},           
            "price":{"type":"double"},           
            "number":{
                "type":"object",
                "dynamic":true
            }
        }
      }
     }
}

执行结果则会出错：Root mapping definition has unsupported parameters

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Root mapping definition has unsupported parameters:  [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "Root mapping definition has unsupported parameters:  [books : {properties={number={dynamic=true, type=object}, price={type=double}, name={index=false, type=text}, title={type=text}, publish_date={index=false, type=date}}}]"
    }
  },
  "status": 400
}

如果在6.x上执行，则会正常执行

{
  "acknowledged" : true
}

出现这个的原因是，elasticsearch7默认不在支持指定索引类型，默认索引类型是_doc，如果想改变，则配置include_type_name: true 即可(这个没有测试，官方文档说的，无论是否可行，建议不要这么做，因为elasticsearch8后就不在提供该字段)。官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html

所以在Elasticsearch7中应该这么创建索引

put /test
{
  "settings":{
    "number_of_shards":3,
    "number_of_replicas":2
  },
  "mappings":{
    "properties":{
      "id":{"type":"long"},
      "name":{"type":"text","analyzer":"ik_smart"},
      "text":{"type":"text","analyzer":"ik_max_word"}
    }
  }
 
}
 
 
put /test1
{
  "settings":{
    "number_of_shards":3,
    "number_of_replicas":2
  },
  "mappings":{
    "properties":{
      "id":{"type":"long"},
      "name":{"type":"text"},
      "text":{"type":"text"}
    }
  }
 
}
