j8583cn's Introduction
这是J8583CN的说明: (C) 2008 zyplanke J8583CN,是8583报文格式在**的事实标准的JAVA实现。(很多地方参考了**银联2.0和某些商行的标准,本程序在某商行各系统的测试项目中使用通过) 由于原来J8583和**的实际标准在某些地方不完全一致,所以在J8583 1.2的基础上进行了改进。为了尽可能的保留利用J8583原来的代码,这此的原始代码来源于J8583,类结构基本不变,为区分,新类名以cn开头。 主要变化如下: 1、 所有的初始代码均来自于J8583 1.2版,对类名名字和部分方法名进行了改变。 2、 为方便使用,将Jakarta Commons Logging 1.1.1 一起打包,使用时不必再次下载。所有的代码用JavaSE6进行编译,因此要求至少JVM5或以上环境运行(IDE is Eclipse 3.4.0 and subversion 1.5.1)。 3、 将cnMessageFactory类中createFromClasspathConfig改为createFromXMLConfigFile,并要求传入参数为XML文件的绝对路径(或运行时的相对路径)。 4、 原来的报文类型标识符以数字表示,先改成字符串(按规范应为4字节串,但不强制,以方便做异常测试) 5、 修改了XML配置文件(DTD文件也相应进行了修改)(新的配置用法见 《XML配置说明.rtf》)。 6、 将报文头做了改进,由于报文头是可以自己定义的,所以报文头现在改成字节串,根据实际对报文头的要求按进行灵活设置,见相关API文档 7、 请求/回应报文的报文标识按8583规范:回应报文为请求报文标识第三位加一(比如请求为0200,回应为0210)。原j8583把报文标示按16进制处理(相差16),先改成字符串,所以相应的也做了变更。 8、 把位图部分做了改进,现在位图只能为8个或16个字节(二进制64bit或128bit,不存在非二进制的问题) 9、 保留了原J8583中对报文是否二进制拼串的属性和方法,但现在这个属性的值,只控制各个报文域的是否以二进制,而报文头、报文类型标识、位图等不受影响。 10、在cnMessage类增加了估算整个报文长度的方法,以方便特殊地方需要(如在银联2.0标准中报文头的第三域) 由上述变化而导致其他地方相应的改变,再此不一一说明。 对于使用者,可以不用了解原来的J8583,而直接用本J8583CN即可。示例参见example中的源代码。 感谢j8583的原作者 Enrique Zamudio。 本人E-Mail:[email protected] ************************************************************* follow is original README.txt of J8583 package --------------------------------------------------------- j8583 (C)2007 Enrique Zamudio The purpose of this library is to simplify the creation, transmission, and parsing of ISO8583 messages.
