java - 如何使用 jpos 解析给定的行？

Question

我使用这个代码:

    import org.jpos.iso.ISOPackager;
    import org.jpos.iso.packager.GenericPackager;
    import org.jpos.iso.packager.ISO87BPackager;
    import org.jpos.iso.ISOException;
    import org.jpos.iso.ISOMsg;
    import org.jpos.iso.ISOUtil;
    import org.junit.Assert;

    public class Utils {
        public static ISOMsg ParseIsoMessage(String hexMsg) throws ISOException {
            // convert hex string to byte array
            byte[] bmsg =ISOUtil.hex2byte(hexMsg);
            ISOMsg mes = new ISOMsg();
            // set packager, change ISO87BPackager for the matching one.
            mes.setPackager(new GenericPackager("resources\\packager.xml"));
            //unpack the message using the packager
            mes.unpack(bmsg);
            //dump the message to standar output
            mes.dump(System.out, "");
            return mes;
        }
    }

102 字段

    packager.xml (
copy with iso87binary.xml with one change):
<isofield
        id="102"
        length="28"
        name="ACCOUNT IDENTIFICATION 1"
        class="org.jpos.iso.IFB_LLCHAR"/>



an error is issued:

org.jpos.iso.ISOException:org.jpos.iso.IFB_LLCHAR:解包字段 102 时出现问题(java.lang.ArrayIndexOutOfBoundsException:10187)解包字段=102，消耗=10187

at org.jpos.iso.ISOBasePackager.unpack(ISOBasePackager.java:340)
at org.jpos.iso.ISOMsg.unpack(ISOMsg.java:468)
at Utils.ParseIsoMessage(Utils.java:17)
at TestHostToHost.test0100(TestHostToHost.java:122)

请帮我看看问题出在哪里。也许另一个类需要在打包器中注册 55 字段？我尝试了不同的。 如何解决这个问题？

Answer 1

显示的数据和打印的原始消息不匹配 原始消息不遵循打包程序定义的格式。 该问题可能发生在字段 102 之前。

为了手动调试，您可以检查位图位置并查看位置是否符合规范。
