起首建立一个东西类,定义好接口,这里的参数
1:fileList:多个文件的path+name
2: zipFileName:紧缩后的文件名
下面是代码,解释已很细致了
public class ZIPUtil { public static String createZipFile(ArrayList<String> fileList, String zipFileName) { if(fileList == null || fileList.size() == 0 || CommonUtil.isEmpty(zipFileName)){ return null; } //构建紧缩文件File File zipFile = new File(zipFileName); //早期化ZIP流 ZipOutputStream out = null; try{ //构建ZIP流对象 out = new ZipOutputStream(new FileOutputStream(zipFile)); //轮回处置惩罚传过来的鸠合 for(int i = 0; i < fileList.size(); i++){ //猎取目的文件 File inFile = new File(fileList.get(i)); if(inFile.exists()){ //定义ZipEntry对象 ZipEntry entry = new ZipEntry(inFile.getName()); //给予ZIP流对象属性 out.putNextEntry(entry); int len = 0 ; //缓冲 byte[] buffer = new byte[1024]; //构建FileInputStream流对象 FileInputStream fis; fis = new FileInputStream(inFile); while ((len = fis.read(buffer)) > 0) { out.write(buffer, 0, len); out.flush(); } //封闭closeEntry out.closeEntry(); //封闭FileInputStream fis.close(); } } }catch (IOException e) { e.printStackTrace(); }finally{ try { //末了封闭ZIP流 out.close(); } catch (IOException e) { e.printStackTrace(); } } return zipFileName; } }
