1、基本信息处理16因为二代身份证里编码为 GB13OO0在java处理中存在问题，总体处理思想为先把进制字节高地位互换，然后用 UTF-16BE转换成中文字符代码如下public static String hexByes2String(byte bytes,String charsetName)if ( .equals(charsetName) charsetName=UTF-16BE;try return new Strin g(bytes,charsetName); catch (Un supportedE ncodi ngExcepti on e) / TODO Auto-ge nera
2、ted catch blocke.pri ntStackTrace();return ;public static byte hexBytesH2L( byte bytes)byte tmp = 0;for ( int i=0;ibytes.length;i+)if (i%2=0) tmp=bytesi;bytesi=bytesi+1;else bytesi=tmp;return bytes;调用：hexByes2String(XSocketUtils.hexBytesH2L(hexBytes),UTF-16BE)情报平台联动升级部省联调测试技术工作要求图片信息处理(用到jna.jar包)图片
3、信息处理必须调用第三方提供dll，GETINFO.DLL，过程是先在java中保存16进制字节为一个 wlt文件在用 GETINFO.DLL中的getBMP 函数，生成bmp图片，在从bmp提取图片字节，函数如下(直接调用 getPictureBytes 即可)import com.s un.jn a.Library;import com.s un.jn a.Native;public class GetSFZPic public interface CLibrary extends Library CLibrary wltToBmp = (CLibrary) Native.loadLibra
4、ry(GETINFO,CLibrary.class);void GetBmp(String wltfile,int a);private static void generatePictureBmp(byte picbytes,String idcard)try String wltfile=System.getProperty( user.dir)+shxxcjxtzp.wlt;if(null!=picbytes)DataOutputStream out=new DataOutputStream(new BufferedOutputStream(new FileOutputStream(wl
5、tfile);out.write(picbytes);out.close();CLibrary.wltToBmp.GetBmp(wltfile, 1); catch (lOException e) e.printStackTrace();public synchronized static byte getPictureBytes(bytepicbytes,String idcard) String filename=System.getProperty( user.d)+shxxcjxtzp.bmp; generatePictureBmp(picbytes,idcard);File file
6、 =new File(filename);if(filename=null | filename.equals()throw new NullPointerException(” 无效的文件路径);long len = file.length();byte bytes = new byte(int)len;System.out.println(filename+len);BufferedInputStream bufferedlnputStream;try bufferedlnputStream = new BufferedInputStream(new FilelnputStream(file);int r = bufferedlnputStream.read( bytes );if (r != len)throw new lOException(” 读取文件不正确); bufferedlnputStream.close(); catch (Exception e) / TODO Auto-generated catch blocke.printStackTrace(); return bytes;第4页共4页
