其实我有下一个代码:
String f = LauncherFrame.class.getProtectionDomain().getCodeSource().getLocation().getPath(); // path to launcher
java.lang.System.out.println(f);
String launcherHash = "";
try{
MessageDigest md5 = MessageDigest.getInstance("MD5");
launcherHash = calculateHash(md5, f);
}catch (Exception e) {
java.lang.System.out.println(e){
return;
}
计算哈希函数:
public static String calculateHash(MessageDigest algorithm,String fileName) throws Exception{
FileInputStream fis = new FileInputStream(fileName);
BufferedInputStream bis = new BufferedInputStream(fis);
DigestInputStream dis = new DigestInputStream(bis, algorithm);
while (dis.read() != -1);
byte[] hash = algorithm.digest();
return byteArray2Hex(hash);
}
当我的 .jar 文件在路径中没有西里尔字符时,它在 unix/windows 上运行良好。但是当它有时,我得到下一个例外:
java.io.FileNotFoundException:
C:\Users\%d0%90%d1%80%d1%82%d1%83%d1%80\Documents\NetBeansProjects\artcraft-client\build\classes (Can't find file)
我该如何解决?
