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。
