Before you can use the java zip API, you need to add some dependencies to your "pom.xml" file.

Here's the minimal dependencies needed in order for the following examples to work:

<dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.5</version> </dependency>

Here's the structure of the Zip file "abc.zip" used in the example below: #|+ abc # |+ abc1 # |+ abc1_1.txt # |+ abc2 # |+ abc2_1.txt

final String zipPath = "/apps/abc.zip"; final Path tempDirectoryPath = Files.createTempDirectory("temp_"); try (final InputStream inputStream = new FileInputStream(zipPath); final ZipInputStream zipInputStream = new ZipInputStream(inputStream)) { ZipEntry zipEntry = zipInputStream.getNextEntry(); while (zipEntry != null) { final String zipEntryName = zipEntry.getName(); final File file = new File(tempDirectoryPath.toFile(), zipEntryName); if (zipEntry.isDirectory()) { System.out.println("Creating the directory \"" + file.getPath()); file.mkdir(); } else { System.out.println("Creating the file \"" + file.getPath()); try (final FileOutputStream fileOutputStream = new FileOutputStream(file)) { IOUtils.copy(zipInputStream, fileOutputStream); } } zipEntry = zipInputStream.getNextEntry(); } }
Output:
Creating the directory "/temp/temp_8417875863245211368/abc Creating the directory "/temp/temp_8417875863245211368/abc/abc1 Creating the file "/temp/temp_8417875863245211368/abc/abc1/abc1_1.txt Creating the directory "/temp/temp_8417875863245211368/abc/abc2 Creating the file "/temp/temp_8417875863245211368/abc/abc2/abc2_1.txt
