Orientdb將CSV文件導入到文檔模型

我想使用ETL將文件導入到Orientdb中的文件模型中csv文件我不知道這是否作爲新手正確，而不是文檔模型上的大量文檔，但我試過是：Orientdb將CSV文件導入到文檔模型

{ 
    "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": [] 
}

顯示該文件的內容的解析之後，我的這句話： [orientdb] DEBUG orientdb：發現在課堂上「空」

的CSV文件0文件

嗨，你能發佈csv文件嗎？你使用什麼版本？ Thx –

@MichelaBonizzi我正在使用2.2.22 oientdb公社版本。至於csv我編輯了問題 –

@MichelaBonizzi有什麼想法嗎？ –

我想你的代碼，我也有同樣的消息：

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

但我已經能夠導入所有的數據，正如你從截圖中看到的那樣。

做到這一點作爲@RobertoFranchini說，你要補充一點：

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

我做了這個小改變您的CSV文件：

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,

和所有的數據已導入。

希望它有幫助。

問候。

謝謝你已經修好了 –

你需要一個類分配給文件，現場變壓器加入連鎖，只要登錄後

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

Franchini，沒有工作我添加了該行，但問題仍然存在 –

在您的重複問題中，您使用class而不是@class。請更新這個問題。 –
