Import Orientdb将csv导入文档模型

我正在尝试使用ETL将csv文件导入Orientdb中的文档模型 作为新手，我不知道这是否正确，关于文档模型的文档也不多，但我尝试的是：

{
  "config": {
    "log": "debug"
  },
  "begin": [],
  "source": {
    "file": {
      "path": "C:/Users/M/Desktop/files/lact.csv"
    }
  },
  "extractor": 
{ "csv": 
      {  "separator": ",", 
         "nullValue": "NULL"
      }
  },
  "transformers": [
    {
      "log": {}
    }
  ],
  "loader": {
    "orientdb": {
      "dbURL": "plocal:../databases/Model_doc",



       "dbType": "document",
      "classes": [
        {
          "name": "Annotations"
        },


      ]
    }
  },
  "end": []
}

在显示文件内容的解析后，我得到这样一句话： [orientdb]调试orientdb:在类“null”中找到0个文档

Csv文件

您需要为文档分配一个类，在日志之后将字段转换器添加到链中

"transformers": [
{
  "log": {}
},
{
  "field": {
    "fieldName": "@class",
    "value": "Annotations"
  }
}
],

我尝试了你的代码，我有同样的信息：

[orientdb] DEBUG orientdb: found 0 documents in class 'null'

但我已经能够导入所有数据，正如你从我的屏幕截图中看到的

要做到这一点，正如@RobertoFranchini所说，您必须添加以下内容：

 "transformers": [
{
  "log": {}
},
{
  "field": {
    "fieldName": "@class",
    "value": "Annotations"
  }
}
],

我对您的csv文件做了以下小更改：

Entry,Entry_name,Status,Protein_names,Gene_names,Organism,Length,Cross_reference(STRING)
Q29836,1B67_HUMAN,reviewed,HLA class I histocompatibility antigen, B-67 alpha chain (MHC class I antigen B*67),HLA-B HLAB,Homo sapiens (Human),362,9606.ENSP00000399168
P30501,1C02_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-2 alpha chain (MHC class I antigen Cw*2),HLA-C HLAC,Homo sapiens (Human),366,
P30508,1C12_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-12 alpha chain (MHC class I antigen Cw*12),HLA-C HLAC,Homo sapiens (Human),366,
Q29960,1C16_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-16 alpha chain (MHC class I antigen Cw*16),HLA-C HLAC,Homo sapiens (Human),366,
Q29865,1C18_HUMAN,reviewed,HLA class I histocompatibility antigen, Cw-18 alpha chain (MHC class I antigen Cw*18),HLA-C HLAC,Homo sapiens (Human),366,

所有数据都已导入

希望能有帮助

问候。

您好，您能发布csv文件吗？你用的是什么版本？Thx@MichelaBonizzi我使用的是2.2.22 oientdb社区版。至于csv，我编辑了question@MichelaBonizzi有什么想法吗？嗨，你能发布csv文件吗？你用的是什么版本？Thx@MichelaBonizzi我使用的是2.2.22 oientdb社区版。至于csv，我编辑了question@MichelaBonizzi有什么想法吗？Franchini，没有用，我加了一行，但问题仍然存在，在你重复的问题中，你使用class而不是@class。请更新此问题。Franchini，不起作用，我添加了行，但问题仍然存在。在重复的问题中，您使用class而不是@class。请更新此问题。
