java压缩中文文件名乱码

在 windows 下进行 zip，然后在 linux 下 unzip，中文的文件名会乱码。 
网上一般的解决办法是重新编译 unzip 来绕过去。 
我查了一下，可以通过 entry.setUnixMode 的方式，将 platform 设置为 Unix，如下： 

 public void setUnixMode(int mode) {
     // CheckStyle:MagicNumberCheck OFF - no point
     setExternalAttributes((mode << 16)
                           // MS-DOS read-only attribute
                           | ((mode & 0200) == 0 ? 1 : 0)
                           // MS-DOS directory flag
                           | (isDirectory() ? 0x10 : 0));
     // CheckStyle:MagicNumberCheck ON
     platform = PLATFORM_UNIX;
 }

这样在解压的时候，就不需要绕过去了。 

另外：要使用 ant 的 zip class，才能解决中文文件名乱码问题，JDK默认的我暂时还不知道如何做。 

 import org.apache.tools.zip.ZipEntry;
 import org.apache.tools.zip.ZipOutputStream;
     public static void write(File path, File zipFile) throws IOException {
         ZipOutputStream zip = new ZipOutputStream(new FileOutputStream(zipFile));
         zip.setEncoding("GBK");
         Util.write(path, path, zip);
         zip.close();
     }

     private static void write(File base, File path, ZipOutputStream zip) throws IOException {
         URI rel = base.toURI().relativize(path.toURI());
         if (path.isDirectory()) {
             ZipEntry entry = new ZipEntry(rel.getPath());
             entry.setUnixMode(755);
             zip.putNextEntry(entry);
             zip.closeEntry();
             File[] files = path.listFiles();
             for (File file : files) {
                 write(base, file, zip);
             }
         } else {
             ZipEntry entry = new ZipEntry(rel.getPath());
             entry.setUnixMode(644);
             zip.putNextEntry(entry);
             FileInputStream is = new FileInputStream(path);
             zip.write(IOUtils.toByteArray(is));
             is.close();
             zip.closeEntry();
         }
     }

方法二：通过修改输出流  编码方法  out.setEncoding("gbk");

有待验证

1:再压缩前，要设置linux模式， 需要使用第三方ant-1.6.5.jar
  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;
