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"}





    }





  }





 





}
