/*** 压缩文件和文件夹** param srcFileString 要压缩的文件或文件夹* param zipFileString 压缩完成的Zip路径* throws Exception*/
public static void ZipFolder(String srcFileString, String zipFileString,String zipName) {//创建ZIPZipOutputStream outZip null;try {//创建文件File file new File(srcFileString);File outPath new File(zipFileString);if (!outPath.exists()){outPath.mkdirs();}outZip new ZipOutputStream(new FileOutputStream(new File(outPath, zipName)));//压缩ZipFiles(file.getParent() File.separator, file.getName(), outZip);isSuccess true;} catch (Exception e) {isSuccess false;e.printStackTrace();} finally {//完成和关闭if (outZip ! null) {try {outZip.finish();outZip.close();}catch (IOException e) {e.printStackTrace();}}}
} 下面这段代码是压缩文件
/*** 压缩文件** param folderString* param fileString* param zipOutputSteam* throws Exception*/
private static void ZipFiles(String folderString, String fileString, ZipOutputStream zipOutputSteam)throws Exception {if (zipOutputSteam null)return;FileInputStream inputStream null;try {File file new File(folderString fileString);if (file.isFile()) {ZipEntry zipEntry new ZipEntry(fileString);inputStream new FileInputStream(file);zipOutputSteam.putNextEntry(zipEntry);int len;byte[] buffer new byte[4096];while ((len inputStream.read(buffer)) ! -1) {zipOutputSteam.write(buffer, 0, len);}zipOutputSteam.closeEntry();} else {//文件夹String fileList[] file.list();//没有子文件和压缩if (fileList.length 0) {ZipEntry zipEntry new ZipEntry(fileString File.separator);zipOutputSteam.putNextEntry(zipEntry);zipOutputSteam.closeEntry();}//子文件和递归for (int i 0; i fileList.length; i) {ZipFiles(folderString fileString /, fileList[i], zipOutputSteam);}}} catch (IOException e) {e.printStackTrace();} finally {if (inputStream ! null) {try {inputStream.close();} catch (IOException ex) {ex.printStackTrace();}}}
}
