mulesoft 中的 dataweave 1.0 到 2.0 迁移

Question

我正在尝试将下面的数据编织从 1.0 转换为 2.0，但我尝试过的所有操作都出现以下错误，例如评估表达式错误、无效输入“reduce”和替换。

Mule 3 数据编织 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
    }   
}

输入负载：https://github.com/Manikandan99/rate-dtostep/blob/master/request.xml

预期输出：https://github.com/Manikandan99/rate-dtostep/blob/master/policy_response.xml

我试过 dataweave 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 
    }   
}

关于如何在 dataweave 2.0 中编写相同的内容有什么想法吗？

为@AnuragSharma 的评论添加更多要点

if-else-if

在你的 dw 中你有 GLClassCode == primaryExposure ， primaryExposure 不存在于你的输入有效负载中因此这将导致空值并且你不能使用 replace 函数以及 null
由于您正在尝试转换为 number ，因此您可以提供 default 值。这里我设置为0.
在输出

encoding="UTF-8"

为了测试您的代码，我已将 GLClasscode 作为 CANDIS 传递给您，就像您在有效负载中所拥有的那样。

注意 - > 请检查括号。

%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
