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;/*** 文件夹压缩，支持win和linux* @author wlzhang**/
