新建索引

PUT /test2
    {
      "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 0
      },
      "mappings": {
        "user":{
          "properties":{
            "id":{
              "type":"long"
            },
            "title":{
              "type":"text",
              "analyzer":"ik_max_word"
            },
            "content":{
              "type":"text",
              "analyzer":"ik_max_word"
            },
            "postdate":{
              "type":"date"
            },
            "url":{
              "type":"text"
            }
          }
        }
      }
    }

然后报错，Root mapping definition has unsupported parameters

{
      "error": {
        "root_cause": [
          {
            "type": "mapper_parsing_exception",
            "reason": "Root mapping definition has unsupported parameters:  [user : {properties={postdate={type=date}, id={type=long}, title={analyzer=ik_max_word, type=text}, content={analyzer=ik_max_word, type=text}, url={type=text}}}]"
          }
        ],
        "type": "mapper_parsing_exception",
        "reason": "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters:  [user : {properties={postdate={type=date}, id={type=long}, title={analyzer=ik_max_word, type=text}, content={analyzer=ik_max_word, type=text}, url={type=text}}}]",
        "caused_by": {
          "type": "mapper_parsing_exception",
          "reason": "Root mapping definition has unsupported parameters:  [user : {properties={postdate={type=date}, id={type=long}, title={analyzer=ik_max_word, type=text}, content={analyzer=ik_max_word, type=text}, url={type=text}}}]"
        }
      },
      "status": 400
    }

**查看官网示例后发现 7.4 默认不在支持指定索引类型，默认索引类型是\_doc（隐含：****include\_type\_name=false）。见官网：[https://www.elastic.co/guide/en/elasticsearch/reference/current/removal-of-types.html\#\_typeless\_apis\_in\_7\_0][https_www.elastic.co_guide_en_elasticsearch_reference_current_removal-of-types.html_typeless_apis_in_7_0]**

修改成：

PUT /test2
    {
      "settings": {
        "number_of_shards": 3,
        "number_of_replicas": 0
      },
      "mappings": {
        "properties":{
          "id":{
            "type":"long"
          },
          "title":{
            "type":"text",
            "analyzer":"ik_max_word"
          },
          "content":{
            "type":"text",
            "analyzer":"ik_max_word"
          },
          "postdate":{
            "type":"date"
          },
          "url":{
            "type":"text"
          }
        }
      }
    }

成功
