7个zip文件(lzma)格式,要压缩和加密。
我想使用Apache Commons Compress
我正在使用此功能,但解压缩的文件已损坏。
由于
public static void main(String args[]) throws FileNotFoundException, IOException {
SevenZOutputFile sevenZOutput = new SevenZOutputFile(new File("outFile.7z"));
File entryFile = new File("D:/image.jpg");
SevenZArchiveEntry entry = sevenZOutput.createArchiveEntry(entryFile, entryFile.getName());
byte fileContent[] = new byte[(int)entryFile.length()];
sevenZOutput.putArchiveEntry(entry);
sevenZOutput.write(fileContent);
sevenZOutput.closeArchiveEntry();
sevenZOutput.close();
}
答案 0 :(得分:0)
我想,好的,谢谢。如何加密存档?
public static void main(String args[]) throws FileNotFoundException, IOException {
SevenZOutputFile sevenZOutput = new SevenZOutputFile(new File("outFile.7z"));
File entryFile = new File("D:/image.jpg");
SevenZArchiveEntry entry = sevenZOutput.createArchiveEntry(entryFile, entryFile.getName());
sevenZOutput.putArchiveEntry(entry);
FileInputStream in = new FileInputStream(entryFile);
int len;
byte buffer[] = new byte[8192];
int transferedMegaBytes2=0;
while ((len = in.read(buffer)) > 0) {
sevenZOutput.write(buffer, 0, len);
transferredBytes += len;
int transferedMegaBytes = (int) (transferredBytes / 1048576);
if(transferedMegaBytes>transferedMegaBytes2){
System.out.println("Transferred: " + transferedMegaBytes + " Megabytes.");
transferedMegaBytes2=transferedMegaBytes;
}
}
sevenZOutput.closeArchiveEntry();
sevenZOutput.close();
}
