我正在尝试将 zip 文件提取到另一个位置,但我收到拒绝访问错误。
代码:
package org.spoutcraft.launcher;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.List;
import java.util.zip.ZipEntry;
import java.util.zip.ZipInputStream;
public class UnZip
{
List<String> fileList;
private static final String INPUT_ZIP_FILE = "C:\\Level Up! Games" + File.separator + "Perfect World" + File.separator + "Updates" + File.separator + "Launcher.zip";
private static final String OUTPUT_FOLDER = "C:\\Level Up! Games" + File.separator + "Perfect World";
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();
}
}
}
在主类中,我使用了以下代码:下载 zip 文件后:
try {
UnZip.main(null);
我得到这个错误:
file unzip : C:\Level Up! Games\Perfect World\config
java.io.FileNotFoundException: C:\Level Up! Games\Perfect World\config (Acesso negado)

有人能帮我吗?
