Azure data factory Azure Data Factory V2数据集动态文件夹

在Azure数据工厂（V1）中，我能够创建一张幻灯片并将输出存储到特定文件夹（即{Year}/{Month}/{Day}）。请参阅下面的代码

如何在Azure Data Factory V2中创建相同类型的切片？我发现必须创建参数。是的，我无法确定如何传递参数

 "folderPath": "@{dataset().path}",
"parameters": {
  "path": {
    "type": "String"

这里是原始的ADF V1代码

以下是将数据从SQL导入ADL时如何创建动态文件夹路径

{
    "name": "EBC_BriefingActivitySummary_L1_Snapshot",
    "properties": {
        "linkedServiceName": {
            "referenceName": "SIAzureDataLakeStore",
            "type": "LinkedServiceReference"
        },
        "type": "AzureDataLakeStoreFile",
        "typeProperties": {
            "format": {
                "type": "TextFormat",
                "columnDelimiter": ",",
                "rowDelimiter": "",
                "nullValue": "\\N",
                "treatEmptyAsNull": false,
                "firstRowAsHeader": false
            },
            "fileName": {
                "value": "EBC.rpt_BriefingActivitySummary.tsv",
                "type": "Expression"
            },
            "folderPath": {
                "value": "@concat('/Snapshots/EBC/rpt_BriefingActivitySummary/', formatDateTime(pipeline().parameters.scheduledRunTime, 'yyyy'), '/', formatDateTime(pipeline().parameters.scheduledRunTime, 'MM'), '/', formatDateTime(pipeline().parameters.scheduledRunTime, 'dd'), '/')",
                "type": "Expression"
            }
        }
    }
}

                "treatEmptyAsNull": false,
                "firstRowAsHeader": false
            },
            "fileName": {
                "value": "EBC.rpt_BriefingActivitySummary.tsv",
                "type": "Expression"
            },
            "folderPath": {
                "value": "@concat('/Snapshots/EBC/rpt_BriefingActivitySummary/', formatDateTime(pipeline().parameters.scheduledRunTime, 'yyyy'), '/', formatDateTime(pipeline().parameters.scheduledRunTime, 'MM'), '/', formatDateTime(pipeline().parameters.scheduledRunTime, 'dd'), '/')",
                "type": "Expression"
            }
        }
    }
}

第1步： 在folderpath中使用WindowsStartTime/WindowEndTime

"folderPath": {
"value": "<<path>>/@{formatDateTime(pipeline().parameters.windowStart,'yyyy')}-@{formatDateTime(pipeline().parameters.windowStart,'MM')}-@{formatDateTime(pipeline().parameters.windowStart,'dd')}/@{formatDateTime(pipeline().parameters.windowStart,'HH')}/",
"type": "Expression"
}

步骤3：在TumblingWindow触发器中添加运行参数 （这在第2步中提到）

   "parameters": {
        "windowStart": {
            "type": "Expression",
            "value": "@trigger().outputs.windowStartTime"
        },
        "windowEnd": {
            "type": "Expression",
            "value": "@trigger().outputs.windowEndTime"
        }
    }
