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;/** * 文件夹压缩，支持win和linux * * */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("UTF-8");// 解决linux乱码 根据linux系统的实际编码设置,可以使用命令// vi/etc/sysconfig/i18n 查看linux的系统编码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();}}private static void unzip(String sourceZip, String destDir)throws Exception {try {Project p = new Project();Expand e = new Expand();e.setProject(p);e.setSrc(new File(sourceZip));e.setOverwrite(false);e.setDest(new File(destDir));/* * ant下的zip工具默认压缩编码为UTF-8编码， 而winRAR软件压缩是用的windows默认的GBK或者GB2312编码 * 所以解压缩时要制定编码格式 */e.setEncoding("UTF-8"); // 根据linux系统的实际编码设置e.execute();} catch (Exception e) {throw e;}}}??
