我想将具有子文件夹结构的压缩文件夹解压缩到单个文件中,而不是在同一个子文件夹中。我有下面的代码,它创建zip的子文件夹结构并复制文件。但我需要将所有文件复制到一个文件夹中。是否可能。
以下是代码: - 公共课UnZip { 列表fileList; private static final String INPUT_ZIP_FILE =" C:\ MyFile.zip&#34 ;; private static final String OUTPUT_FOLDER =" C:\ outputzip&#34 ;;
public static void main( String[] args )
{
UnZip unZip = new UnZip();
unZip.unZipIt(INPUT_ZIP_FILE,OUTPUT_FOLDER);
}
/**
* Unzip it
* @param zipFile input zip file
* @param output zip file output folder
*/
public void unZipIt(String zipFile, String outputFolder){
byte[] buffer = new byte[1024];
try{
//create output directory is not exists
File folder = new File(OUTPUT_FOLDER);
if(!folder.exists()){
folder.mkdir();
}
//get the zip file content
ZipInputStream zis =
new ZipInputStream(new FileInputStream(zipFile));
//get the zipped file list entry
ZipEntry ze = zis.getNextEntry();
while(ze!=null){
String fileName = ze.getName();
File newFile = new File(outputFolder + File.separator + fileName);
System.out.println("file unzip : "+ newFile.getAbsoluteFile());
//create all non exists folders
//else you will hit FileNotFoundException for compressed folder
new File(newFile.getParent()).mkdirs();
FileOutputStream fos = new FileOutputStream(newFile);
int len;
while ((len = zis.read(buffer)) > 0) {
fos.write(buffer, 0, len);
}
fos.close();
ze = zis.getNextEntry();
}
zis.closeEntry();
zis.close();
System.out.println("Done");
}catch(IOException ex){
ex.printStackTrace();
}
}
}
提前致谢!!
