easy and simple 8583 Protocol Analysis for java 我的QQ： 534117529 有任何问题，请邮件联系反馈 目标是让8583协议更简单，更直观，更好用 有多简单？有多直观？ 参见博客：https://blog.csdn.net/yyz_1987/article/details/80838764 以一个签到报文举例：
/** * 签到报文组帧 * @param field * @param tx */
public void frame8583QD( __8583Fields[] field, Pack tx){
//消息类型
tx.MsgType[0] = 0x08;

//11域，受卡方系统跟踪号BCD 通讯流水
field[10].ishave = 1;
field[10].len = 3;
String tmp = String.format("%06d",commSn);
field[10].data = hexStringToBytes(tmp);
//41域，终端号
field[40].ishave = 1;
field[40].len = 8;
field[40].data = PosNum.getBytes();
//42域，商户号
field[41].ishave = 1;
field[41].len = 15;
field[41].data = ManNum.getBytes();
//60域
field[59].ishave = 1;
field[59].len = 0x11;
field[59].data = new byte[6];
field[59].data[0] = 0x00;
arraycopy(piciNum,0,field[59].data,1,3);
field[59].data[4] = 0x00;
field[59].data[5] = 0x30;
//62域
field[61].ishave = 1;
field[61].len = 0x25;
field[61].data = new byte[25];
String str = "Sequence No12";
arraycopy(str.getBytes(),0,field[61].data,0,13);
arraycopy(licenceNum,0,field[61].data,13,4);

//63域

field[62].data[0] = 0x30;

最终组织好的报文在哪呢？在报文结构类Pack中的Txbuffer中，长度为Txlen
需要外部设置的参数在哪放？
外部需要配置的有：终端号，商户号，主秘钥，TPDU。这些在类里定义的有set和get方法。 如何使用？ 如何发送报文给银联后台呢？
假如你通信有Send（byte[] sendbuf, int len） 方法
那么只需 Send（pack.TxBuffer,pack.TxLen）
想打印出来报文日志在哪看？ 直接pack.ToString()即可
附带一个调用的demo:
/** * 调用demo * @param args */
public static void main(String[] args) {
My8583Ans myans = new My8583Ans();
//签到组包
myans.frame8583QD(myans.fieldsSend,myans.pack);
//打印出待发送的报文
byte[] send = new byte[myans.pack.txLen];
arraycopy(myans.pack.txBuffer,0,send,0,myans.pack.txLen);
System.out.println("->send:");
System.out.println(My8583Ans.bytesToHexString(send));
System.out.println(myans.pack.toString());
System.out.println(myans.getFields(myans.fieldsSend));
//接收解析,假如收到的报文在recv中
String recvstr ="007960000001386131003111080810003800010AC0001450021122130107200800085500323231333031343931333239303039393939393930363030313433303137303131393939390011000005190030004046F161A743497B32EAC760DF5EA57DF5900ECCE3977731A7EA402DDF0000000000000000CFF1592A";
System.out.println("->recv:"+recvstr);
byte[] recv = My8583Ans.hexStringToBytes(recvstr);
// mypack.ans8583Fields(bt,bt.length,mypack.fieldsRecv);

System.out.println("开始解析...");
int ret = myans.ans8583QD(recv,recv.length);
if(ret == 0){
//打印出解析成功的各个域
System.out.println("签到成功!");
System.out.println(myans.getFields(myans.fieldsRecv));
}
//二维码组包
System.out.println("->二维码交易 demo");
String qrcode = "6223360612494957384";
int money = 1; //1分
myans.frame8583Qrcode(qrcode,money,myans.fieldsSend,myans.pack);
//打印出待发送的报文
send = new byte[myans.pack.txLen];
arraycopy(myans.pack.txBuffer,0,send,0,myans.pack.txLen);
