Today encountered a file package into the zip problem, with the previous method found that win10 system generated by the zip package, and some files can not be compressed when the compression file.
So I refer to a new method for sharing and taking notes
1, need to rely onant-*.jar
2. Write a ZipUtil utility class
package com.chinagdn.chengh.util;
import java.io.*;
import java.nio.charset.Charset;
import java.util.Enumeration;
import java.util.zip.ZipEntry;
import java.util.zip.ZipFile;
public class ZipUtil {
/** ** Use GBK encoding to avoid garbled Chinese file names */
private static final String CHINESE_CHARSET = "GBK";
/** * File read buffer size */
private static final int CACHE_SIZE = 1024;
private ZipUtil(a) {
// Private construct master method. Because this class is a utility class.
}
/** * <p> * compressed file * </p> **@paramSourceFolder * The path of the file or folder to be compressed *@paramZipFilePath * Zip file output path *@throws Exception
*/
public static void zip(String sourceFolder, String zipFilePath) throws Exception {
OutputStream out = new FileOutputStream(zipFilePath);
BufferedOutputStream bos = new BufferedOutputStream(out);
org.apache.tools.zip.ZipOutputStream zos = new org.apache.tools.zip.ZipOutputStream(bos);
// Resolve garbled Chinese file names
zos.setEncoding(CHINESE_CHARSET);
File file = new File(sourceFolder);
String basePath = null;
if (file.isDirectory()) {
basePath = file.getPath();
} else {
basePath = file.getParent();
}
zipFile(file, basePath, zos);
zos.closeEntry();
zos.close();
bos.close();
out.close();
}
/** * <p> * compressed file * </p> **@paramSourceFolders * A group of compressed folders or files *@paramZipFilePath * Zip file output path *@throws Exception
*/
public static void zip(String[] sourceFolders, String zipFilePath) throws Exception {
OutputStream out = new FileOutputStream(zipFilePath);

org.apache.tools.zip.ZipOutputStream zos = new org.apache.tools.zip.ZipOutputStream(bos);
// Resolve garbled Chinese file names
zos.setEncoding(CHINESE_CHARSET);
for (int i = 0; i < sourceFolders.length; i++) {
File file = new File(sourceFolders[i]);
String basePath = null;
basePath = file.getParent();
zipFile(file, basePath, zos);
}
zos.closeEntry();
zos.close();
bos.close();
out.close();
}

zos.putNextEntry(new org.apache.tools.zip.ZipEntry(pathName));

public static void main(String[] args) throws Exception {

ZipUtil.unZipFiles(zipFile, path); / /
/ / ZipUtil. Zip (" f: / download/accessories ", "f: / download/test.zip"); packaging
}
Copy the code4. If you need to pack files in different folders
-
Create a temporary folder for packaging
File dirTemp = new File("D :// temporary folder"); if((! dirTemp.exists()) && (! dirTemp.isDirectory())) { dirTemp.mkdirs(); }Copy the code -
Use commons-io utility classes to copy files to a temporary folder
//FileUtils.copyFileToDirectory(File srcFile, File destDir); // Move 1.txt to drive D/temporary folder FileUtils.copyFileToDirectory(new File("c://1.txt"), new File("D :// temporary folder")); FileUtils.copyFileToDirectory(new File("f://2.txt"), new File("D :// temporary folder")); Copy the code -
Use your own written utility classes for packaging
//zip(String sourceFolder, String zipFilePath) // Package the files under the temporary folder into test.zip ZipUtil.zip("D :// temporary folder"."d://test.zip"); FileUtils.deleteDirectory(new File("D :// temporary folder")); // Delete temporary files Copy the code
