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; } } }?
