apache ant进行zip解压缩操作示例分享

需要导入ant.jar包，apache网站（http://ant.apache.org/bindownload.cgi）下载即可。

复制代码代码如下:

import java.io.BufferedInputStream;

import java.io.BufferedOutputStream;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.util.zip.ZipOutputStream;

import org.apache.tools.ant.Project;

import org.apache.tools.ant.taskdefs.Expand;

import org.apache.tools.zip.ZipEntry;

import com.xyq.io.util.CloseIoUtil;

public class ZipUtil {

private static final String ENCODE = "UTF-8";

public static void zip(String inputFilePath, String zipFileName) {

File inputFile = new File(inputFilePath);

if (!inputFile.exists())

throw new RuntimeException("原始文件不存在!!!");

File basetarZipFile = new File(zipFileName).getParentFile();

if (!basetarZipFile.exists() && !basetarZipFile.mkdirs())

throw new RuntimeException("目标文件无法创建!!!");

BufferedOutputStream bos = null;

FileOutputStream out = null;

ZipOutputStream zOut = null;

try {

// 创建文件输出对象out,提示:注意中文支持

out = new FileOutputStream(new String(zipFileName.getBytes(ENCODE)));

bos = new BufferedOutputStream(out);

// 文件出ZIP输出流接起来

zOut = new ZipOutputStream(bos);

zip(zOut, inputFile, inputFile.getName());

CloseIoUtil.closeAll(zOut, bos, out);

} catch (Exception e) {

e.printStackTrace();

}

}

private static void zip(ZipOutputStream zOut, File file, String base) {

try {

// 如果文件句柄是目录

if (file.isDirectory()) {

// 获取目录下的文件

File[] listFiles = file.listFiles();

// 建立ZIP条目

zOut.putNextEntry(new ZipEntry(base + "/"));

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

if (listFiles != null && listFiles.length > 0)

// 遍历目录下文件

for (File f : listFiles)

// 递归进入本方法

zip(zOut, f, base + f.getName());

}

// 如果文件句柄是文件

else {

if (base == "") {

base = file.getName();

}

// 填入文件句柄

zOut.putNextEntry(new ZipEntry(base));

// 开始压缩

// 从文件入流读,写入ZIP 出流

writeFile(zOut, file);

}

} catch (Exception e) {

e.printStackTrace();

}

}

private static void writeFile(ZipOutputStream zOut, File file)

throws IOException {

FileInputStream in = null;

BufferedInputStream bis = null;

in = new FileInputStream(file);

bis = new BufferedInputStream(in);

int len = 0;

byte[] buff = new byte[2048];

while ((len = bis.read(buff)) != -1)

zOut.write(buff, 0, len);

zOut.flush();

CloseIoUtil.closeAll(bis, in);

}
