I have a directory with some folders that should be skipped and not added to the target ZIP
file. I marked them as hidden on Windows
and I can query this attribute using Java code as follows:
new File("C:\\myHiddenFolder").isHidden();
However, I don't know how to use this with the following Zip4j
-based method to skip adding those respective directories:
public File createZipArchive(String sourceFilePath) throws ZipException, IOException
{
ZipParameters zipParameters = new ZipParameters();
zipParameters.setCompressionMethod(Zip4jConstants.COMP_DEFLATE);
zipParameters.setCompressionLevel(Zip4jConstants.DEFLATE_LEVEL_ULTRA);
zipParameters.setEncryptFiles(true);
zipParameters.setEncryptionMethod(Zip4jConstants.ENC_METHOD_AES);
zipParameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);
zipParameters.setPassword("MyPassword");
String baseFileName = FileNameUtilities.getBaseFileName(sourceFilePath);
String destinationZipFilePath = baseFileName + "." + EXTENSION;
ZipFile zipFile = new ZipFile(destinationZipFilePath);
File sourceFile = new File(sourceFilePath);
// Recursively add directories
if (sourceFile.isDirectory())
{
File[] childrenFiles = sourceFile.listFiles();
if (childrenFiles != null)
{
for (File folder : childrenFiles)
{
if (folder.isHidden()) // Nope, no recursive checking!
{
// This is the problem, it adds the parent folder and all child folders without allowing me to check whether to exclude any of them...
zipFile.addFolder(folder.getAbsolutePath(), zipParameters);
}
}
}
} else
{
// Add just the file
zipFile.addFile(new File(sourceFilePath), zipParameters);
}
return zipFile.getFile();
}
Note that this method only works when the (hidden) folders are in the most upper level but it should work for any depth.

为了解决这个问题,我将所有隐藏文件夹移出,打包zip文件并将文件夹移回:
HiddenDirectoriesMover hiddenDirectoriesMover = new HiddenDirectoriesMover(sourceFilePath);
hiddenDirectoriesMover.removeFiles();
// Create zip
hiddenDirectoriesMover.returnFiles();
肮脏的解决办法,但自zipParameters.setReadHiddenFiles(false);
is not working as expected以来完成工作:
public static ArrayList getFilesInDirectoryRec(File path,
boolean readHiddenFiles) throws ZipException {
if (path == null) {
throw new ZipException("input path is null, cannot read files in the directory");
}
ArrayList result = new ArrayList();
File[] filesAndDirs = path.listFiles();
List filesDirs = Arrays.asList(filesAndDirs);
if (!path.canRead()) {
return result;
}
for(int i = 0; i < filesDirs.size(); i++) {
File file = (File)filesDirs.get(i);
if (file.isHidden() && !readHiddenFiles) {
// The first hidden file causes a return and skipping everything else (!)
return result;
}
result.add(file);
if (file.isDirectory()) {
List deeperList = getFilesInDirectoryRec(file, readHiddenFiles);
result.addAll(deeperList);
}
}
return result;
}

您可以添加zipParameters.setReadHiddenFiles(false);
,zip4j不会将隐藏的文件夹和文件添加到ZipFile
。
