我写了一个代码来压缩所选目录中的文件，但是它没有在子目录中搜索文件，我找到了一个我插入的循环，但似乎仍然没有用。
如果有人可以帮助我修改我的代码，那么它会搜索插入路径中的所有文件夹。
请参阅以下代码：
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;
import javax.swing.JOptionPane;
public class List {
private static void getFiles(File folder, java.util.List<File> list) throws FileNotFoundException, IOException {
String v_days; // number of days inserted
v_days = JOptionPane.showInputDialog("Enter duration of days back that should be archived? (Numerical Value)");
folder.setWritable(true);
File[] files = folder.listFiles();
long purgeTime = System.currentTimeMillis() - ((long)Integer.parseInt(v_days) * 24 * 60 * 60 * 1000); //Calculate how old files must be before they get archived
try {
for (int j = 0; j < files.length; j++) {
if (files[j].lastModified() < purgeTime ) {
list.add(files[j]);
if (files[j].isDirectory()) {
getFiles(files[j], list);
{
byte[] buffer = new byte[4096]; // create byte buffer
String zipFileName = files[j].getAbsolutePath() + ".zip" ; //Create the final zip name of the file
String zipFileFullPath = files[j].getAbsolutePath() ; //Get the full path of the normal file before being zipped
System.out.println("Starting with file: " + zipFileFullPath );
System.out.println("File name will be: " + files[j].getAbsolutePath() + ".zip") ;
FileOutputStream fos = new FileOutputStream(zipFileName); //Add the final zip name to the output stream
ZipOutputStream zos = new ZipOutputStream(fos); //Add the final zip name to the output stream
FileInputStream fis = new FileInputStream(files[j]); //Add the current file for the iteration into the input stream
zos.putNextEntry(new ZipEntry(files[j].getName())); //Adds the filename of the current file for the iteration into the zip file
int length;
while ((length = fis.read(buffer)) > 0) //While there is anything in the buffer, write it
{
zos.write(buffer, 0, length);
}
zos.closeEntry(); //Close the entry into the output stream
fis.close(); //Close the input stream
zos.close(); //Close the output stream
System.out.println("Done with file: " + zipFileFullPath) ;
try
{
boolean success = (new File(zipFileFullPath)).delete();
if ((success) && (files[j].lastModified() < purgeTime))//If file zipped successfully and the file is older than days inserted, then delete
{
System.out.println("The files has been successfully deleted");
}
else
{
System.out.println("Error occurred, could not delete files");
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
}
}
catch (IOException ioe) //Exception Handling
{
System.out.println("Error creating zip file" + ioe);
}
}
}
public static void main(String[] args) throws IOException {
File folder = new File("C:\\Users\\kroon_000\\Desktop\\test.zip");
java.util.List<File> list = new ArrayList<File>();
getFiles(folder, list);
}
}
