java - Apache Commons Compress：ZipArchiveEntry.getUnixMode() 始终返回 0

Question

在分析结果文件时，该值被正确写入，所以setUnixMode()可能工作正常，但getUnixMode()总是返回 0。有没有人有这方面的经验？

File file = new File("Test.file");
ZipArchiveOutputStream zipArchiveOutputStream = new ZipArchiveOutputStream(new FileOutputStream(file));   
ZipArchiveEntry zipArchiveEntry = new ZipArchiveEntry("Entry");  
zipArchiveEntry.setUnixMode(0744);
zipArchiveOutputStream.putArchiveEntry(zipArchiveEntry);
zipArchiveOutputStream.write("TestBytes".getBytes());
zipArchiveOutputStream.closeArchiveEntry();
zipArchiveOutputStream.close();
                        
ZipArchiveInputStream zipArchiveInputStream = new ZipArchiveInputStream(new FileInputStream(file));
ZipArchiveEntry entryOut = zipArchiveInputStream.getNextZipEntry();
System.out.println(entryOut.getUnixMode());

Answer 1

当平台 != PLATFORM_UNIX 时，getUnixMode() 返回 0（源代码请参见此处）。所以你还必须指定平台：zipArchiveEntry.setPlatform(ZipArchiveEntry.PLATFORM_UNIX)
