無法在OrientDB中導入數據

Question

我想在OrientDB中上傳數據，但是有錯誤。 這是json文件：嘗試將數據上傳到csv文件中，並與服務器和虛擬機建立鏈接

{
    "source": {
        "file": {
            "path": "/root/Orientdb/bin/temp/datasets/server.csv"
        }
    },
    "extractor": {
        "row": {}
    },
    "transformers": [{
        "csv": {
            "separator": ",",
            "columnsOnFirstLine": false,
            "columns": ["name", "description", "servercategory", "primarysupport", "secondarysupport", "powersource", "serialnumber", "brand", "model", "serverlocation", "osfamily", "osversion", "cpuspeed", "ram", "numberofprocessor", "cpucorecount", "leftpowersource", "rightpowersource"]
        }
    }, {
        "vertex": {
            "class": "Server"
        }
    }, {
        "merge": {
            "joinFieldName": "virtualhost",
            "lookup": "Server.name"
        }
    }, {
        "edge": {
            "class": "VirtualMachine",
            "joinFieldName": "to",
            "lookup": "Server.name",
            "unresolvedLinkAction": "CREATE"
        }
    }],
    "loader": {
        "orientdb": {
            "dbURL": "plocal:/databases/GratefulDeadConcerts",
            "dbType": "graph",
            "wal": false,
            "batchCommit": 1000,
            "tx": true,
            "txUseLog": false,
            "useLightweightEdges": true,
            "classes": [{
                "name": "Server",
                "extends": "V"
            }, {
                "name": "VirtualMachine",
                "extends": "E"
            }],
            "indexes": [{
                "class": "Server",
                "fields": ["id:name"],
                "type": "UNIQUE"
            }]
        }
    }
}

但是，運行命令（./oetl.sh server.json）之后會出現錯誤。 我應該怎么做才能解決這個問題？ 或者我不應該在運行腳本之前創建類（服務器和虛擬機）？ 謝謝。

錯誤消息是

我已經在Google網上論壇上回答了您https://groups.google.com/forum/#!topic/orient-database/XxdE3UnhFPA

Answer 2

請在json中使用下面的merge和edge塊並檢查。

{“ merge”：{“ joinFieldName”：“到”，“ lookup”：“ Server.name”}}，{“ edge”：{“ class”：“ VirtualMachine”，“ joinFieldName”：“ virtualhost”，“ lookup “：” Server.name“，” unresolvedLinkAction“：” CREATE“}

謝謝
