方法:
package zip; import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; // Used to zip a file public class FileZipper { private static final int BUFFER = 512; public boolean compressFilesToZip(String[] files,String zipfile) { return rugularZip(files,zipfile); } private boolean rugularZip(String[] fromFiles,String toFile) { File zipFile=new File(toFile); byte[] buffer=new byte[BUFFER]; int readLen=0; try { ZipOutputStream zipOut=new ZipOutputStream(new FileOutputStream(zipFile)) ; int index=0; for(String file:fromFiles) { File fileWillZip=new File(file); if(fileWillZip.exists()) { InputStream inputStream=new BufferedInputStream(new FileInputStream(fileWillZip)); String entryName="#"+index+"_"+fileWillZip.getName();// entryName should be a valid filename,no path seperater allowed zipOut.putNextEntry(new ZipEntry(entryName)); while((readLen=inputStream.read(buffer,0,BUFFER))!=-1) { zipOut.write(buffer,0,readLen); } inputStream.close(); index++; } } zipOut.close(); }catch(Exception e) { e.printStackTrace(); return false; } return true; } public static void main(String[] args) { String[] files= {"D:\\wallpaper\\5760666873360998521.jpg", "D:\\wallpaper\\luda1.jpg", "D:\\wallpaper\\luda2.jpg", "D:\\wallpaper\\luda3.jpg", "D:\\wallpaper\\luda4.jpg", "D:\\wallpaper\\sheeps.jpg"}; String zipfile="D:\\wallpaper\\result.zip"; FileZipper fz=new FileZipper(); fz.compressFilesToZip(files, zipfile); } }
