j8583：ISOMessage解析器未按预期产生输出

Question

I am using j8583 iso parser to parse ISO Message.

"0800A020 00000080 00100400 00000000 00000000 00000001 32393131 30303031 00105445 5354204D 45535347 0301"

Below is my code.

import com.solab.iso8583.IsoMessage;
import com.solab.iso8583.IsoValue;
import com.solab.iso8583.MessageFactory;
import com.solab.iso8583.parse.ConfigParser;

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;
import java.text.ParseException;

    public class ISOUtility {

        private static BufferedReader reader;

        private static String getMessage() throws IOException {
            if (reader == null) {
                reader = new BufferedReader(new InputStreamReader(System.in));
            }
         //   System.out.println("Paste your ISO8583 message here (no ISO headers): ");
            return "08002020 00000080 00000000 00000001 32393131 30303031";
        }

        public static void main(String [] args) throws IOException, ParseException {
         // System.out.println("Hello");
            final MessageFactory<IsoMessage> mf = new MessageFactory<IsoMessage>();

           if (1 == 0) {
            //   System.out.println("Hello2");

            //  ConfigParser.createFromClasspathConfig("j8583.xml");
                ConfigParser.configureFromDefault(mf);

            }  else {
                System.out.println("Hello3");
                String path="C:\\Users\\DELL\\workspace\\SolabParser\\j8583.xml";
                if (System.console() != null) {
                    System.console().printf("Attempting to configure MessageFactory from %s...%n", path);

                }
                System.out.println("Messagefactory is done");
                String url = "C:\\Users\\DELL\\workspace\\SolabParser\\j8583.xml";
                if (url.contains("://")) {
                    System.out.println("else ");

                    ConfigParser.configureFromUrl(mf, new URL(args[0]));
                } else {
                    System.out.println("else ");
                    ConfigParser.configureFromUrl(mf, new File(path).toURI().toURL());
                }
            }
            //Now read messages in a loop
            String line = getMessage();
          //  while (line != null && line.length() > 0) {

            mf.setIgnoreLastMissingField(true);
                System.out.println(mf.getIgnoreLastMissingField());

                IsoMessage m = mf.parseMessage(line.getBytes(), 0);

                System.out.println("Hello5");
                if (m != null) {
                    System.out.printf("Message type: %04x%n", m.getType());
                    System.out.println("FIELD TYPE    VALUE");
                    for (int i = 2; i <= 128; i++) {
                        IsoValue<?> f = m.getField(i);
                        if (f != null) {
                            System.out.printf("%5d %-6s [", i, f.getType());
                            System.out.print(f.toString());
                            System.out.println(']');
                        }
                    }
                }
                line = getMessage();
         //   }
        }

But I am getting incorrect output.

Message type: 0800
FIELD TYPE    VALUE
    3 ALPHA  [000000]
   11 NUMERIC [00 000]
   41 NUMERIC [00001 32393131 3]
   60 LLLVAR [3031 00105445 5354204D 4553534]
   70 NUMERIC [7 0]

Except field 3, all have incorrect data.

If I make any changes with space in data, it throws** error:**

Insufficient data for LLLVAR field 60

Any sugeestion to get this over with.

Thank You.

Answer 1

As I replied in comments:

1) Remove the spaces from the message buffer.

2) Check your message format profile.

Looks like Field 60 in your case has 4 chars for the length. ie LLLLVAR.
