JAVA压缩 解压缩zip 并解决linux下中文乱码

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: 

  1 import java.io.File;
  2 import java.io.FileInputStream;
  3 import java.io.FileOutputStream;
  4 import java.io.OutputStream;

  6 import org.apache.tools.zip.ZipEntry;

  9 import org.apache.tools.ant.Project;

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