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:



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;

import org.apache.tools.ant.Project;

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

			ZipEntry zipEntry = new ZipEntry(base);
