Java 实现解压 TR_2023063012.tar.gz 这种格式的压缩包
递归文件夹，找到tar.gz 格式的压缩包，并且进行解压，解压到这个压缩包所在的文件夹下
2 实现
代码语言：javascript复制 public static void main(String[] args) {
String depth = "D:\data";
ArrayList<String> strings = new ArrayList<>();
List<String> gz = FileUtils.listFile(strings, new File(depth), true, "gz");
for (String item:gz){
File file = new File(item);
File parentFile = file.getParentFile();
String absolutePath = parentFile.getAbsolutePath();
try {
uncompressTarGz(item, absolutePath);
System.out.println("File uncompressed successfully.");
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(item);
}
// String inputFilePath = "D:\059\data\RAIN_GRIB\2023060200\TR_2023060200.tar.gz"; // 压缩包文件路径
// String outputFolderPath = "D:\059\data\RAIN_GRIB\2023060200\"; // 解压输出文件夹路径
//
// try {
// uncompressTarGz(inputFilePath, outputFolderPath);
// System.out.println("File uncompressed successfully.");
// } catch (IOException e) {
// e.printStackTrace();
// }
}
private static void uncompressTarGz(String inputFilePath, String outputFolderPath) throws IOException {
try (FileInputStream fileInputStream = new FileInputStream(inputFilePath);
BufferedInputStream bufferedInputStream = new BufferedInputStream(fileInputStream);
GzipCompressorInputStream gzipInputStream = new GzipCompressorInputStream(bufferedInputStream);
TarArchiveInputStream tarInputStream = new TarArchiveInputStream(gzipInputStream)) {
TarArchiveEntry entry;
while ((entry = (TarArchiveEntry) tarInputStream.getNextEntry()) != null) {
if (!entry.isDirectory()) {
File outputFile = new File(outputFolderPath, entry.getName());
createParentDirectory(outputFile);
try (OutputStream outputStream = new FileOutputStream(outputFile)) {
byte[] buffer = new byte[1024];
int length;
while ((length = tarInputStream.read(buffer)) != -1) {
outputStream.write(buffer, 0, length);
}
}
}
}
}
}
private static void createParentDirectory(File file) {
File parent = file.getParentFile();
if (parent != null && !parent.exists()) {
parent.mkdirs();
}
}
