ElasticSearch6.x 之JSON 數據導入（Windows平臺）

第一步：注意事項

使用json文件可以給es中導入數據，10萬條左右的數據可以一次導入，數量太大時導入就會報錯。大數量的到導入還是需要用bulk方式。

第二步：創建website 索引，並且指定映射關係

編輯內容：

{
  "settings": {
    "number_of_replicas": 1,
    "number_of_shards": 5
  },
  "mappings": {
    "blog":{
      "properties": {
        "title":{
          "type":"text",
          "analyzer": "ik_max_word"
        },
        "author":{
          "type":"text"
        },
        "postdate":{
          "type":"date",
          "format": "yyyy-MM-dd"
        },
        "abstract":{
          "type":"text",
          "analyzer": "ik_max_word"
        },
        "url":{
          "type":"text"
        }
      }
    }  
  }
}

第二步：文檔數據導入json文件(website.json)

第三步：windows cmd 窗口模式，執行如下指令，進行本地json 數據導入es 中：

windows10下的curl需要先下載windows版的curl，再輸入命令：

curl  -H "Content-Type: application/json" -XPOST  192.168.1.74:9200/website/blog/_bulk?pretty --data-binary "@C:\data\website.json" 

含義解釋：H參數：指定請求頭的數據格式，-XPOST ：post 請求，      /website/blog:代表website 索引下類型爲blog   data-binary:json 數據存儲地址。

第四步：驗證json 數據是否導入成功，執行如下命令。
