如何使用Java压缩文件夹本身

可以通过软件包轻松解决，

java.util.Zip

Jar

只需复制以下代码，并

run it

IDE

//import all needed packagespackage general;import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.zip.ZipEntry;import java.util.zip.ZipOutputStream;public class ZipUtils {    private List <String> fileList;    private static final String OUTPUT_ZIP_FILE = "Folder.zip";    private static final String SOURCE_FOLDER = "D:\Reports"; // SourceFolder path    public ZipUtils() {        fileList = new ArrayList < String > ();    }    public static void main(String[] args) {        ZipUtils appZip = new ZipUtils();        appZip.generateFileList(new File(SOURCE_FOLDER));        appZip.zipIt(OUTPUT_ZIP_FILE);    }    public void zipIt(String zipFile) {        byte[] buffer = new byte[1024];        String source = new File(SOURCE_FOLDER).getName();        FileOutputStream fos = null;        ZipOutputStream zos = null;        try { fos = new FileOutputStream(zipFile); zos = new ZipOutputStream(fos); System.out.println("Output to Zip : " + zipFile); FileInputStream in = null; for (String file: this.fileList) {     System.out.println("File Added : " + file);     ZipEntry ze = new ZipEntry(source + File.separator + file);     zos.putNextEntry(ze);     try {         in = new FileInputStream(SOURCE_FOLDER + File.separator + file);         int len;         while ((len = in .read(buffer)) > 0) {  zos.write(buffer, 0, len);         }     } finally {         in.close();     } } zos.closeEntry(); System.out.println("Folder successfully compressed");        } catch (IOException ex) { ex.printStackTrace();        } finally { try {     zos.close(); } catch (IOException e) {     e.printStackTrace(); }        }    }    public void generateFileList(File node) {        // add file only        if (node.isFile()) { fileList.add(generateZipEntry(node.toString()));        }        if (node.isDirectory()) { String[] subNote = node.list(); for (String filename: subNote) {     generateFileList(new File(node, filename)); }        }    }    private String generateZipEntry(String file) {        return file.substring(SOURCE_FOLDER.length() + 1, file.length());    }}
