mulesoft 中的 dataweave 1.0 到 2.0 遷移

Question

我正在嘗試將下面的數據編織從 1.0 轉換為 2.0，但我嘗試過的所有操作都會出現以下錯誤，例如評估表達式錯誤、無效輸入“減少”和替換。

騾子 3 數據編織 1.0：

%dw 1.0
%output application/xml
%var basicPolicy = payload.DTOApplication.DTOBasicPolicy
%var insuredInfo = payload.DTOApplication.DTOInsured
%var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
%var lineLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "Liability")][0]
%var lineProperty = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "CommercialProperty")][0]
%var lineProductLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "ProductLiability")][0]
%var primaryClassTotalExposure = lineLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == primaryExposure)].@Exposure default [] reduce ((val,acc=0) -> acc + (val replace "\$" with "" replace "," with "") as :number)
%var primaryClassPLTotalExposure = lineProductLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == primaryExposurePL)].@Exposure default [] reduce ((val,acc=0) -> acc + (val replace "\$" with "" replace "," with "") as :number)

{
    
    Policy: {
        PolType: basicPolicy.@SubTypeCd default "",
        Zip: insuredPrimaryAddr.@PostalCode[0..4] default "",
        EffDate: basicPolicy.@EffectiveDt default "",
        ExpDate: basicPolicy.@ExpirationDt default "",
        EBCov: lineProperty.@EquipmentBreakdown default "No",
        PolFeeOR2: payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "",
        PolFeeOR: (payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount default "") when payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount != null
                    otherwise (payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "")  when payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt != null
                    otherwise "",
        LiabExp: primaryClassTotalExposure,
        ProdExp: primaryClassPLTotalExposure
    }   
}

預計 output： https://github.com/Manikandan99/rate-dtostep/blob/master/policy_response.xml

我試過數據編織 2.0：

%dw 2.0
output application/xml
var basicPolicy = payload.DTOApplication.DTOBasicPolicy
var insuredInfo = payload.DTOApplication.DTOInsured
var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
var lineLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "Liability")][0]
var lineProperty = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "CommercialProperty")][0]
var lineProductLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "ProductLiability")][0]
var primaryClassTotalExposure = lineLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == primaryExposure)].@Exposure default [] reduce ((val,acc=0) -> acc + (val replace "\$" with "" replace "," with "") as :number)
var primaryClassPLTotalExposure = lineProductLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == primaryExposurePL)].@Exposure default [] reduce ((val,acc=0) -> acc + (val replace "\$" with "" replace "," with "") as :number)

{
    
    Policy: {
        PolType: basicPolicy.@SubTypeCd default "",
        Zip: insuredPrimaryAddr.@PostalCode[0 to 4] default "",
        EffDate: basicPolicy.@EffectiveDt default "",
        ExpDate: basicPolicy.@ExpirationDt default "",
        EBCov: lineProperty.@EquipmentBreakdown default "No",
        PolFeeOR2: payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "",
        PolFeeOR: (payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount default "") when payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount != null
                    otherwise (payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "")  when payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt != null
                    otherwise "",
        LiabExp: primaryClassTotalExposure,
        ProdExp: primaryClassPLTotalExposure 
    }   
}

關於如何在 dataweave 2.0 中編寫相同內容的任何想法？

Answer 1

在@AnuragSharma 的評論中再添加幾點

如果-其他-如果

1. 在您的 dw 中，您有GLClassCode == primaryExposure ，輸入有效負載中不存在primaryExposure因此這將導致 null 值，您不能replace function 與 null 一起使用
2. 由於您正在嘗試轉換為數字，因此您可以提供一個default值。 這里我設置為0。
3. output中要求添加encoding="UTF-8"

為了測試您的代碼，我已將GLClasscode 作為 CANDIS傳遞給您，就像您在有效負載中所擁有的那樣。

注意->請同時檢查您的括號。

%dw 2.0
output application/xml encoding="UTF-8"
var basicPolicy = payload.DTOApplication.DTOBasicPolicy
var insuredInfo = payload.DTOApplication.DTOInsured
var insuredPrimaryAddr = insuredInfo.*PartyInfo[?($.@PartyTypeCd == "InsuredParty")].*Addr[?($.@AddrTypeCd == "InsuredPrimaryBusAddr")][0]
var lineLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "Liability")][0]
var lineProperty = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "CommercialProperty")][0]
var lineProductLiability = payload.DTOApplication.*DTOLine[?($.@StatusCd == "Active" and $.@LineCd == "ProductLiability")][0]
var primaryClassTotalExposure = lineLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == "CANDIS")].@Exposure default [] reduce ($$++$) replace "\$" with "" replace "," with "" default 0  as Number
var primaryClassPLTotalExposure = lineProductLiability.*DTORisk[?($.@Status == "Active" and $.@TypeCd == "Exposure")].*DTOGLClass[?($.@GLClassCode == "CANDIS")].@Exposure default []  reduce ($$++$) replace "\$" with "" replace "," with "" default 0 as Number

        Zip: insuredPrimaryAddr.@PostalCode[0 to 4] default "",
        EffDate: basicPolicy.@EffectiveDt default "",
        ExpDate: basicPolicy.@ExpirationDt default "",
        EBCov: lineProperty.@EquipmentBreakdown default "No",
        PolFeeOR2: payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "",
        PolFeeOR: if (payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount != null)
                        (payload.DTOApplication.DTOFeeOverrides.*DTOFeeOverride[?($.@Code == "POLF" and $.@OverrideInd == "Yes")][0].@Amount default "") 
                else if (payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt != null)
                    (payload.DTOApplication.*DTOFee[?($.@Status == "Active" and $.@RateDRCFeeInd == "No")][0].@FullTermAmt default "")  
                    else "",
        LiabExp: primaryClassTotalExposure,
        ProdExp: primaryClassPLTotalExposure 
    }   
}

Output
