java - JPos - ISO8583 消息 TLV 字段

Question

我正在使用 jpos 库构建一个简单的电子购买金融消息，我正在使用通用打包器来打包我的消息字段，问题出现在字段 48(TLV 字段)处。

这里是字段 48 的打包参数。

        <isofieldpackager id="48"
            name="Additional Private Data"

    ISOMsg authISOMsg = new ISOMsg();

上面的主要代码表示包含一些字段的财务消息，我遇到的问题发生在字段 48。

下面的错误引发以下异常。

    Nested:org.jpos.iso.ISOException: Error reading deploy\packager\basic-packager.xml (org.xml.sax.SAXParseException; systemId: file:basic-packager.xml; 
    lineNumber: 114; columnNumber: 64; Attribute "tagMapper" must be declared for element type "isofieldpackager").

Answer 1

看来您需要使用generic-subtag-packager.dtd验证您的 xml 打包器定义。

您可以将该文件复制到 xml 所在的目录中，并用 doctype 定义替换该文件:

<!DOCTYPE isopackager SYSTEM "generic-subtag-packager.dtd">

我希望这能解决您的问题。
