Json 使用 Jolt 进行顶级数组转换

Question

我正在尝试使用 Jolt 执行从顶级 json 数组到另一个数组的复杂转换。在每个项目中，我有几个对象需要映射到另一个对象。当它是简单的字符串时，我可以很容易地映射它们，但是当它是关于对象到对象的时候，我不知道该怎么做。在下面的示例中，我想从 customer 对象中提取数据。我想为其他几个人做这件事，比如 addresses 和 order_items 这是我的输入：

[
    {
        "tax_amount": "0.0000",
        "shipping_discount_amount": "0.0000",
        "addresses": [
            {
                "firstname": "kevin",
                "address_type": "billing",

这是规范文件

[
  {
    "operation": "shift",
    "spec": {
      "orders": {
        "*": {
          "customer": {
            "entity_id": "customer[&1].id",
            "firstname": "customer[&1].firstName",
            "lastname": "customer[&1].lastName",
            "dob": "customer[&1].birthDate"
          },
          "increment_id": "[&1].saleId",
          "created_at": "[&1].saleDate",

          "grand_total": "[&1].totalAmount"
        }
      }
    }
  }
]

目前，我的输出是

[ {
  "saleDate" : "2014-11-12 16:40:58",
  "saleId" : "200000002",
  "shippingFeesVTA" : "0.0000",
  "shippingFeesWithoutTax" : "5.0000",
  "totalAmount" : "5.0000"
}, {
  "saleDate" : "2015-01-13 11:45:26",

  "shippingFeesVTA" : "0.0000",
  "shippingFeesWithoutTax" : "5.0000",
  "totalAmount" : "5.0000"
} ]

我希望这样:

[ {
  "saleDate" : "2014-11-12 16:40:58",
  "saleId" : "200000002",
  "shippingFeesVTA" : "0.0000",
  "shippingFeesWithoutTax" : "5.0000",
  "totalAmount" : "5.0000",
  "customer": {
    "id": 1,
    "firstName": "kevin",
    "lastName":"test",
    "birthDate":"1980-11-03 00:00:00"
  }
}, {
  "saleDate" : "2015-01-13 11:45:26",
  "saleId" : "200000003",
  "shippingFeesVTA" : "0.0000",
  "shippingFeesWithoutTax" : "5.0000",
  "totalAmount" : "5.0000",
  "customer": {
    "id": 1,
    "firstName": "kevin",
    "lastName":"test",
    "birthDate":"1980-11-03 00:00:00"
  }
} ]

有人知道怎么做吗？

更新： 我怎样才能将我的 order_items 数组转换为另一个数组？相同的输入，但输出为：

这个规范做到了

[
  {
    "operation": "shift",
    "spec": {
      "orders": {
        "*": {
          "increment_id": "[&1].saleId",
          "created_at": "[&1].saleDate",
          "shipping_amount": "[&1].shippingFeesWithoutTax",
          "shipping_tax_amount": "[&1].shippingFeesVTA",
          "grand_total": "[&1].totalAmount",

          "customer": {
            "entity_id": "[&2].customer.id",
            "firstname": "[&2].customer.firstName",
            "lastname": "[&2].customer.lastName",
            "dob": "[&2].customer.birthDate"
          }
        }
      }
    }
  }
]
