es Root mapping definition has unsupported parameters解决方法

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"}}}}
