Question

我正在尝试对工作中的一个非常复杂的程序进行一些更改。该程序使用JAXB，并具有许多不同的类和功能。在它的核心，目的是允许用户创建表示基于卡的事务的XML文件。现在，用户可以输入金额，然后将金额输入最终的XML中。我需要扩展这一点，同时让用户能够将事务分成多个部分。这意味着我需要能够更改金额字段。对我来说不幸的是，作者设计金额字段的方式有点混乱，所以我希望有人可以解释一下。有大量的代码，我无法粘贴所有代码，但我会尽力展示问题。

我正在使用的代码的主要部分是：

while(allocationCounter>0){
            StructuredRemittanceInformation9 Strd = objectFactory
                    .createStructuredRemittanceInformation9(); // create Strd
            ReferredDocumentInformation3 RfrdDocInf = objectFactory
                    .createReferredDocumentInformation3(); // create RfrdDocInf
            ReferredDocumentType2 tpdoc = objectFactory
                    .createReferredDocumentType2(); // create tp
            ReferredDocumentType1Choice cdOrPrtry = objectFactory
                    .createReferredDocumentType1Choice(); // create CdOrPrtry
            cdOrPrtry.setCd(DocumentType5Code.SOAC);
            tpdoc.setCdOrPrtry(cdOrPrtry); // set CdorPrtry
            RfrdDocInf.setTp(tpdoc); // set Tp
            RfrdDocInf.setNb("0001");
            Strd.getRfrdDocInf().add(RfrdDocInf); // set RfrdDocInf

            RemittanceAmount2 RfrdDocAmt = objectFactory.createRemittanceAmount2(); // create
                                                                                    // RfrdDocAmt
            DocumentAdjustment1 adjstmntAmt = objectFactory
                    .createDocumentAdjustment1(); // create AdjstmntAmtAndRsn
            ActiveOrHistoricCurrencyAndAmount adjAmt = objectFactory
                    .createActiveOrHistoricCurrencyAndAmount(); // create Amt


            adjAmt.setCcy("USD");
            adjAmt.setValue((BigDecimal) transInfo.get("amount"));      
            adjstmntAmt.setAmt(adjAmt); // set Amt
            adjstmntAmt.setCdtDbtInd(CreditDebitCode.DBIT); // set CdtDbtInd
            adjstmntAmt.setAddtlInf(transInfo.get("dbtrName").toString()); // set
                                                                            // AddtlInf
            RfrdDocAmt.getAdjstmntAmtAndRsn().add(adjstmntAmt); // set
                                                                // AdjstmntAmtAndRsn
            Strd.setRfrdDocAmt(RfrdDocAmt); // set RfrdDocAmt

            CreditorReferenceInformation2 cdtrRefInf = objectFactory
                    .createCreditorReferenceInformation2(); // create CdtrRefInf
            CreditorReferenceType2 cdtrTp = objectFactory
                    .createCreditorReferenceType2(); // create Tp
            CreditorReferenceType1Choice CdorPrtryTp = objectFactory
                    .createCreditorReferenceType1Choice(); // create cdPrtry
            CdorPrtryTp.setPrtry("BNR");
            cdtrTp.setCdOrPrtry(CdorPrtryTp);// set CdPrtry
            cdtrRefInf.setTp(cdtrTp); // set Tp
            cdtrRefInf.setRef(transInfo.get("referenceNumber").toString());
            Strd.setCdtrRefInf(cdtrRefInf);// set CdtrRefInf

            rmtInf.getStrd().add(Strd); // set strd

            System.out.println("TEST PASSED");
            allocationCounter--;
            }

特别是这行代码

adjstmntAmt.setAmt(adjAmt); // set Amt

这就是设定金额的原因，而这正是我需要改变的。这个数量链接回几个类，但从这里开始：

transactionInfo.put("amount", amount);

在该类中，用户将金额放入文本字段，然后保存我在上面发布的adjstmntAmt（adjAmt）在另一个类中引用：进入transactionInfo哈希并稍后调用。

所以我的问题很简单：我需要做些什么来使我能够将任何变量放在那行代码中：

adjstmntAmt.setAmt(adjAmt); // set Amt

我尝试用自己的变量替换adjAmt但是我得到一个错误，说明类型必须是ActiveOrHistoricCurrencyAndAmount ..

非常感谢任何帮助！

Answer 1

我终于找到了这个问题的答案。实际解决方案以此字段的形式出现

adjAmt.setValue((BigDecimal) transInfo.get("amount"));

我可以用我想要的数量替换括号中的数量。这个金额实际上与另一个我没有在原始问题中发布的课程有关，其中＆＃34;金额＆＃34;实际上是在JTextField中设置然后保存到HashMap。

将变量转换为bigDecimal
