我正在使用以下代码在Java中解压缩zip文件。
import java.io.*;
import java.util.zip.*;
class testZipFiles
{
public static void main(String[] args)
{
try
{
String filename = "C:\\zip\\includes.zip";
testZipFiles list = new testZipFiles( );
list.getZipFiles(filename);
}
catch (Exception e)
{
e.printStackTrace();
}
}
public void getZipFiles(String filename)
{
try
{
String destinationname = "c:\\zip\\";
byte[] buf = new byte[1024];
ZipInputStream zipinputstream = null;
ZipEntry zipentry;
zipinputstream = new ZipInputStream(
new FileInputStream(filename));
zipentry = zipinputstream.getNextEntry();
while (zipentry != null)
{
//for each entry to be extracted
String entryName = zipentry.getName();
System.out.println("entryname "+entryName);
int n;
FileOutputStream fileoutputstream;
File newFile = new File(entryName);
String directory = newFile.getParent();
if(directory == null)
{
if(newFile.isDirectory())
break;
}
fileoutputstream = new FileOutputStream(
destinationname+entryName);
while ((n = zipinputstream.read(buf, 0, 1024)) > -1)
fileoutputstream.write(buf, 0, n);
fileoutputstream.close();
zipinputstream.closeEntry();
zipentry = zipinputstream.getNextEntry();
}//while
zipinputstream.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
很明显,由于break语句的存在,这段代码无法提取文件夹结构。我尝试使用递归处理文件夹结构,但失败了。请有经验的人士指导如何改进此代码以处理文件夹树,而不是压缩的单层文件夹。
