JOLT Trasform - Help Needed

[#1]

Hi community,

i'm fighting with my JOLT transform, hope someone can help me on this.

I have the following json flow file:

[
  {
    "StartName": "<My_Start_Name_1>",
    "StartAddress": "<My_Start_Address_1>",
    "EndName": "<My_End_Name_1>",
    "EndAddress": "My_End_Address_1",
    "CubeSped": 0.58,
    "WeightSped": 36
  },
  {
    "StartName": "<My_Start_Name_2>",
    "StartAddress": "<My_Start_Address_2>",
    "EndName": "<My_End_Name_2>",
    "EndAddress": "My_End_Address_2",
    "CubeSped": 0.88,
    "WeightSped": 22
  }
]

My expected result should be:

{
    "Data": {
      "MessageId": "<My_Random_ID>",
      "MessageDate": "<My_Current_Date>",
      "Client": "<My_Customer>",
      "Order": [
        {
          "ProcessType": {
            "ReturnOrder": {
            }
          },
          "FreightTerm": "PointOfUse",
          "OrderNumber": "123456789160X",
          "OrderNumber2": "123456789160X",
          "TransmissionCommand": "Create",
          "SequenceNumber": "1",
          "SenderAbbreviation": "Test",
          "CustomerAddress": {
            "Name": "<My_Start_Name_1>",
            "Street": "<My_Start_Address_1>"
          },
          "ShipmentAddress": {
            "Name": "<My_End_Name_1>",
            "Street": "<My_End_Address_1>"
          },
          "Volume": "1",
          "Weight": "365"
        },
        {
            "ProcessType": {
                "ReturnOrder": {
                }
            },
            "FreightTerm": "PointOfUse",
            "OrderNumber": "123456789160X",
            "OrderNumber2": "123456789160X",
            "TransmissionCommand": "Create",
            "SequenceNumber": "1",
            "SenderAbbreviation": "Test",
            "CustomerAddress": {
                "Name": "<My_Start_Name_2>",
                "Street": "<My_Start_Address_2>"
            },
            "ShipmentAddress": {
                "Name": "<My_End_Name_2>",
                "Street": "<My_End_Address_2>"
            },
            "Volume": "1",
            "Weight": "365"
            }
        ]
    }
}

 Currently my spec are:

[
  {
    "operation": "shift",
    "spec": {
      "*": {
        "CubeSped": "Order[&1].Volume",
        "WeightSped": "Order[&1].Weight",
        "DocNumLDC": "Order[&1].OrderNumber",
        "StartName": "Order[&1].CustomerAddress.Name",
        "StartAddress": "Order[&1].CustomerAddress.Street",
        "EndName": "Order[&1].ShipmentAddress.Name",
        "EndAddress": "Order[&1].ShipmentAddress.Street"
      }
    }
  }, {
    "operation": "default",
    "spec": {
      "Order[]": {
        "*": {
          "top-level": {
            "ProcessType": {
              "ReturnOrder": ""
            },
            "FreightTerm": "PointOfUse",
            "OrderNumber2": "123456789160X",
            "TransmissionCommand": "Create",
            "SequenceNumber": "1",
            "SenderAbbreviation": "Test"
          }
        }
      }
    }
  }
]

Which becomes:

{
  "Order" : [ {
    "Volume" : 0.58,
    "Weight" : 36,
    "CustomerAddress" : {
      "Name" : "<My_Start_Name_1>",
      "Street" : "<My_Start_Address_1>"
    },
    "ShipmentAddress" : {
      "Name" : "<My_End_Name_1>",
      "Street" : "My_End_Address_1"
    },
    "top-level" : {
      "TransmissionCommand" : "Create",
      "ProcessType" : {
        "ReturnOrder" : ""
      },
      "FreightTerm" : "PointOfUse",
      "SequenceNumber" : "1",
      "SenderAbbreviation" : "Test",
      "OrderNumber2" : "123456789160X"
    }
  }, {
    "Volume" : 0.88,
    "Weight" : 22,
    "CustomerAddress" : {
      "Name" : "<My_Start_Name_2>",
      "Street" : "<My_Start_Address_2>"
    },
    "ShipmentAddress" : {
      "Name" : "<My_End_Name_2>",
      "Street" : "My_End_Address_2"
    },
    "top-level" : {
      "TransmissionCommand" : "Create",
      "ProcessType" : {
        "ReturnOrder" : ""
      },
      "FreightTerm" : "PointOfUse",
      "SequenceNumber" : "1",
      "SenderAbbreviation" : "Test",
      "OrderNumber2" : "123456789160X"
    }
  } ]
}

The point is:

• is there any way to move elements on top?
• is there a better way to achieve the result?
• Does anything else can be used instead of JOLT?

The result schema is needed after in order to covert everything into xml.

Many thanks for any help, appreciate.

Hey,

Generally JOLT tries to maintain the input order. The only way that I can think about is an hard-coded approach.

Add this after the default spec:

{
    "operation": "shift",
    "spec": {
      "Order": {
        "*": {
          "top-level": {
            "ProcessType": "[&2].ProcessType",
            "FreightTerm": "[&2].FreightTerm",
            "OrderNumber2": "[&2].OrderNumber2",
            "TransmissionCommand": "[&2].TransmissionCommand",
            "SequenceNumber": "[&2].SequenceNumber",
            "SenderAbbreviation": "[&2].SenderAbbreviation"
          },
          "CustomerAddress": "[&1].CustomerAddress",
          "ShipmentAddress": "[&1].ShipmentAdress",
          "Volume": "[&1].Volume",
          "Weight": "[&1].Weight"
        }
      }
    }
  }

Also, are you trying to "duplicate" the value of "OrderNumber2"?

The other solution I can remember to "replace" JOLT is by using FasterXML/Jackson
