Zip4j从Zip排除文件夹 [英] Zip4j Excluding Folders from Zip
问题描述
我有一个包含一些文件夹的目录,应该跳过这些文件夹,不要将其添加到目标 ZIP
文件中。我在 Windows
上将它们标记为隐藏,然后可以使用Java代码查询此属性,如下所示:
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();
但是,我不知道如何在以下 Zip4j
为基础的方法,以跳过添加相应目录的操作:
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();
}
请注意,此方法仅在(隐藏)文件夹位于最
Note that this method only works when the (hidden) folders are in the most upper level but it should work for any depth.
推荐答案
为解决此问题,我将所有隐藏文件夹移出,打包了zip文件文件,然后将文件夹移回:
To solve this I went with moving all hidden folders out, package the zip file and move the folders back:
HiddenDirectoriesMover hiddenDirectoriesMover = new HiddenDirectoriesMover(sourceFilePath);
hiddenDirectoriesMover.removeFiles();
// Create zip
hiddenDirectoriesMover.returnFiles();
一个肮脏的解决方法,但是由于 zipParameters.setReadHiddenFiles(false );
无法正常工作:
A dirty work-around but does the job since zipParameters.setReadHiddenFiles(false);
is not working as expected:
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;
}
