zip *** zipPath参数为保存zip的文件路径 srcPath参数为需要压缩的目录 在linux window上面测试无问题!主要是编码问题比较麻烦~要是有其他异常 请留言 或者 有什么更好的 *** 欢迎给更多的意见　　//zip zhe folder　　void zip(String zipPath, String srcPath,javax.servlet.jsp.JspWriter out) throws Exception {　　FileOutputStream output = null;　　ZipOutputStream zipOutput = null;　　try{　　output = new FileOutputStream(zipPath);　　zipOutput = new ZipOutputStream(output);　　zipEntry(zipOutput,srcPath,srcPath,zipPath);　　}catch(Exception e){　　out.print(file zip error);　　}finally{　　if(zipOutput!=null)zipOutput.close();　　}　　out.print(zip ok zipPath);　　}　　//add the zip entry　　void zipEntry(ZipOutputStream zipOs, String initPath,String filePath,String zipPath) throws Exception {　　String entryName = filePath;　　File f = new File(filePath);　　if (f.isDirectory()){// ??　　String[] files = f.list();　　for(int i = 0; i files.length; i )　　zipEntry(zipOs, initPath, filePath File.separator files[i],zipPath);　　return;　　}　　String chPh = initPath.substring(initPath.lastIndexOf(/) 1);// ?????　　int idx=initPath.lastIndexOf(chPh);　　if (idx != -1) {　　entryName = filePath.substring(idx);　　}　　ZipEntry entry;　　entry = new ZipEntry(entryName);　　File ff = new File(filePath);　　if(ff.getAbsolutePath().equals(zipPath))return;　　entry.setSize(ff.length());　　entry.setTime(ff.lastModified());　　//the CRC efficacy　　entry.setCrc(0);　　CRC32 crc = new CRC32();　　crc.reset();　　zipOs.putNextEntry(entry);　　int len = 0;　　byte[] buffer = new byte[2048];　　int bufferLen = 2048;　　FileInputStream input =null;　　try{　　input = new FileInputStream(filePath);　　while ((len = input.read(buffer, 0, bufferLen)) != -1) {　　zipOs.write(buffer, 0, len);　　crc.update(buffer, 0, len);　　}　　}catch(Exception e){　　}finally{　　if(input!=null)input.close();　　}　　entry.setCrc(crc.getValue());　　}
