java怎样压缩文件夹

java怎样压缩文件夹,第1张

压缩文件夹代码:

import java.io.File

import org.apache.tools.zip.ZipOutputStream//扰哪孝这个包在ant.jar里,要到官方网下载

import java.io.FileInputStream

import java.io.FileOutputStream

import java.util.zip.ZipInputStream

import java.util.zip.ZipEntry

public class CompressBook {

public CompressBook() {}

/*

* inputFileName 输入一个文件夹

* zipFileName 输出一个压缩文件夹

*/

public void zip(String inputFileName) throws Exception {

String zipFileName = "c:\\test.zip"//打包后文件名字缓缓

System.out.println(zipFileName)

zip(zipFileName, new File(inputFileName))

}

private void zip(String zipFileName, File inputFile) throws Exception {

ZipOutputStream out = new ZipOutputStream(new FileOutputStream(zipFileName))

zip(out, inputFile, "")

System.out.println("zip done")

out.close()

}

private void zip(ZipOutputStream out, File f, String base) throws Exception {

if (f.isDirectory()) {

File[] fl = f.listFiles()

out.putNextEntry(new org.apache.tools.zip.ZipEntry(base + "/"))

base = base.length() == 0 ? "" : base + "/"缓稿

}

}
