Question

这是我目前的配置文件

＆＃13;

{
	"config": {
		"haltOnError": false
	},
	"source": {
		"file": {
			"path": "/home/user1/temp/real_user/user3.csv"
		}
	},
	"extractor": {
		"csv": {
			"columns": ["id", "name", "token", "username", "password", "created", "updated", "enabled", "is_admin", "is_banned", "userAvatar"],
			"columnsOnFirstLine": true
		},
		"field": {
			"fieldName": "created",
			"expression": "created.asDateTime()"
		}
	},
	"transformers": [{
		"vertex": {
			"class": "user"
		}
	}],
	"loader": {
		"orientdb": {
			"dbURL": "plocal:/home/user1/orientdb/real_user",
			"dbAutoCreateProperties": true,
			"dbType": "graph",
			"classes": [{
				"name": "user",
				"extends": "V"
			}],
			"indexes": [{
				"class": "user",
				"fields": ["id:long"],
				"type": "UNIQUE"
			}]
		}
	}
}

我的csv目前看起来像这样

我仍然想知道当我执行ETL时，orientdb不会将我的日期时间识别为日期时间。

我尝试将数据类型放在列字段中＆＃34; created：datetime＆＃34;，但它最终没有显示任何数据。

我想知道这种情况的正确解决办法是什么。

Answer 1

从下一版本2.2.8开始，您将能够为日期和日期时间定义不同的默认模式：CSV extractor documentation

请注意，在定义列时，需要指定列的类型：

            "columns": ["id:string", "created:date", "updated:datetime"],

您可以使用2.2.8 ETL模块和2.2.7的快照jar，没有任何问题：
