我正在尝试解压缩 ISO 8583 消息，但在尝试解压缩第 46 个字段时出现错误，指出长度不能超过 204。请查找我的 ISO 消息：

嗨，我尝试了以下代码： package stack.examples;

import org.jpos.iso.ISOException;
import org.jpos.iso.ISOMsg;
import org.jpos.iso.ISOPackager;
import org.jpos.iso.packager.GenericPackager;
import org.jpos.util.Logger;
import org.jpos.util.SimpleLogListener;

public class ParserError {

    public static void main(String[] args) throws ISOException {
        String msg = "1200F07405C188C480000100000C1400000410114040200050007700000001320061000000111318201608071619349912090099099001200151059990648742906BANK02701214010962 ibank00000000000000003470404C0000000000000000D00000000404404129EBP123SVCT0000204PAYD00103sort|40402000|;sort2|40478000|;phone2|254716191411|;terminal_id| ibank|;transaction_type|credit_push|07RTPSNIF07RTPSNIF07RTPSNIF1301003013812000011sahalksjdls";
        Logger logger = new Logger();
        logger.addListener(new SimpleLogListener());
        GenericPackager pkgr = new GenericPackager("src/test/resources/packager.xml");

        ISOMsg m = new ISOMsg();
        m.setPackager(pkgr);
        pkgr.setLogger(logger, "packager");

        m.unpack(msg.getBytes());
    }

}

问题是您的 parser.xml 定义中有错位，长度为 10 的 pan（字段 2）似乎很奇怪，但它似乎解析正常，直到字段 33“BANK02”字段 41 似乎已经坏了。您对每个领域的期望是什么？这可能会导致猜测 parser.xml 中的问题所在。

前面代码的输出如下：
