【Java 基础篇】Java Zip压缩：简化文件和文件夹的压缩操作
可以使用ZipOutputStream类来创建一个新的Zip文件，并指定文件名。 zipOutputStream = new ZipOutputStream(new FileOutputStream(zipFileName))) { // 添加文件到压缩包 ... // 完成当前文件的压缩 zipOutputStream.closeEntry(); } } 在上面的示例中，我们首先创建了一个ZipOutputStream zipOutputStream = new ZipOutputStream(new FileOutputStream(zipFileName))) { // 添加文件到压缩包 zipOutputStream = new ZipOutputStream(new FileOutputStream(zipFileName))) { // 压缩文件夹

Java中zip的压缩和解压缩
在Java中可以使用ZipOutputStream和ZipInputStream来实现zip的压缩和解压缩操作，另外使用FileSystem也可以用来实现zip的解压缩，下面将介绍这几种方式，直接上代码 每个zip文件项都要对应一个ZipEntry，然后通过ZipOutputStream的putNextEntry方法开始写入一个新的zip文件项，将文件数据发送到zip输出流中，完成后再调用closeEntry @Test public void testCompressByZip() { try ( //指定压缩完成后zip文件的存储路径 ZipOutputStream zipOutputStream = new ZipOutputStream(new FileOutputStream("F:\\myFavorites.zip")) ) { //待压缩文件/目录所在的目录 File fileFolder (); } zipOutputStream.closeEntry(); } } catch (IOException ex) { ex.printStackTrace(); }
