Java Apache Commons压缩7zip，损坏文件错误

Question

7 zip文件（lzma）格式，想要压缩和加密。
我想使用Apache Commons Compress。
我正在使用此功能，但是，解压缩的文件已损坏。

感谢

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();   
}

我想，好吧，谢谢你。我如何加密档案？

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();  
}
