我需要解包所有包含zip文件的文件。但是zip文件中还包含一个.tar文件。考虑以下路径：原始zip路径：e:\test\26-03-2016\order\7930199\u 1.zip提取路径：e:\test\26-03-2016\order\7930199\u 1\itemfile\1458887416277\u 12\ftp\content providers\ewh-e\data\incomingabp

In the Extracted path ,The folder contains a .tar file as OBX00000000005442A.tar and it has several folders with in it.

我已提取到incomingabp，但无法提取.tar文件。请帮助我提取这个.tar文件。下面我提供了我的代码片段。

代码从这里开始

static public void extractFolder(String zipFile) throws 
ZipException,     
 IOException 
{
System.out.println(zipFile);
int BUFFER = 2048;
File file = new File(zipFile);
ZipFile zip = new ZipFile(file);
String newPath = zipFile.substring(0, zipFile.length() - 4);
new File(newPath).mkdir();
Enumeration zipFileEntries = zip.entries();
// Process each entry
while (zipFileEntries.hasMoreElements())
{
    // grab a zip file entry
    ZipEntry entry = (ZipEntry) zipFileEntries.nextElement();
    String currentEntry = entry.getName();
    File destFile = new File(newPath, currentEntry);
    //destFile = new File(newPath, destFile.getName());
    File destinationParent = destFile.getParentFile();
    // create the parent directory structure if needed
    destinationParent.mkdirs();
    if (!entry.isDirectory())
    {
        BufferedInputStream is = new BufferedInputStream(zip
        .getInputStream(entry));
        int currentByte;
        // establish buffer for writing file
        byte data[] = new byte[BUFFER];
        // write the current file to disk
        FileOutputStream fos = new FileOutputStream(destFile);
        BufferedOutputStream dest = new BufferedOutputStream(fos,
        BUFFER);
        // read and write until last byte is encountered
        while ((currentByte = is.read(data, 0, BUFFER)) != -1) {
            dest.write(data, 0, currentByte);
        }
        dest.flush();
        dest.close();
        is.close();
    }
    if (currentEntry.endsWith(".zip")||currentEntry.endsWith(".tar"))
    {
        // found a zip file, try to open
        extractFolder(destFile.getAbsolutePath());
    }
 }
}
}

有人能帮我提取这个吗？提前感谢strack trace:e:\test\26-03-2016\order\7930199\u 1.zip e:\test\26-03-2016\order\7930199\u 1\itemfile\1458887416277\u 12.zip e:\test\26-03-2016\order\7930199\u 1\itemfile\1458887416277\u 12\ftp\content-providers\ewh-e\data\incomingabp\obx0000005442a.tar
