ElasticSearch6.x 之JSON 数据导入（Windows平台）

第一步：注意事项

使用json文件可以给es中导入数据，10万条左右的数据可以一次导入，数量太大时导入就会报错。大数量的到导入还是需要用bulk方式。

第二步：创建website 索引，并且指定映射关系

编辑内容：

{ 
  "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：文档数据导入json文件(website.json)

第三步：windows cmd 窗口模式，执行如下指令，进行本地json 数据导入es 中：

windows10下的curl需要先下载windows版的curl，再输入命令：

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

含义解释：H参数：指定请求头的数据格式，-XPOST ：post 请求，      /website/blog:代表website 索引下类型为blog   data-binary:json 数据存储地址。

第四步：验证json 数据是否导入成功，执行如下命令。
