前几天写了文章介绍java文件夹的压缩(见

http://zwllxs.iteye.com/blog/836483)，但是发现一个问题，在linux下，如果文件夹内的文件是中文名，那么压缩后，这些文件名全部成为了乱码而无法解压,要能支持linux压缩，有两点：

1:再压缩前，要设置linux模式，

如果是文件目录，则

ZipEntry zipEntry=new ZipEntry(basePath + System.getProperties().getProperty("file.separator"));

zipEntry.setUnixMode(755);//解决linux乱码

如果是文件，则

ZipEntry zipEntry=new ZipEntry(base);

zipEntry.setUnixMode(644);//解决linux乱码

然后在输出时强制设置编码:

ZipOutputStream out = new ZipOutputStream(new FileOutputStream(

zipFileName));

out.setEncoding("GBK");//解决linux乱码

全部代码如下:

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.OutputStream;

import org.apache.tools.zip.ZipEntry;

import org.apache.tools.zip.ZipOutputStream;

/**

* 文件夹压缩，支持win和linux

* @author wlzhang

*/

public class ZipUtil

{

/**

* @param inputFileName

* 输入一个文件夹

* @param zipFileName

* 输出一个压缩文件夹，打包后文件名字

* @throws Exception

*/

public static OutputStream zip(String inputFileName, String zipFileName) throws Exception

{

return zip(zipFileName, new File(inputFileName));

}

private static OutputStream zip(String zipFileName, File inputFile) throws Exception

{

ZipOutputStream out = new ZipOutputStream(new FileOutputStream(

zipFileName));

out.setEncoding("GBK");//解决linux乱码

zip(out, inputFile, "");

out.close();

return out;

}

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

{

if (f.isDirectory())

{ // 判断是否为目录

File[] fl = f.listFiles();

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

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

ZipEntry zipEntry=new ZipEntry(base + System.getProperties().getProperty("file.separator"));

zipEntry.setUnixMode(755);//解决linux乱码

out.putNextEntry(zipEntry);

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

base = base.length() == 0 ? "" : base + System.getProperties().getProperty("file.separator");

for (int i = 0; i < fl.length; i++)

{

zip(out, fl[i], base + fl[i].getName());

}

}

else

{ // 压缩目录中的所有文件

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

ZipEntry zipEntry=new ZipEntry(base);

zipEntry.setUnixMode(644);//解决linux乱码

out.putNextEntry(zipEntry);

FileInputStream in = new FileInputStream(f);

int b;

while ((b = in.read()) != -1)

{

out.write(b);

}

in.close();

}

}

}

以上代码就同时支持win和linux
