1、maven 中引入 apache 解壓 / 壓縮 工具類
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-compress -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-compress</artifactId>
<version>1.20</version>
</dependency>
2、代碼中使用
(1)將 tar.gz 轉換爲 tar
(2)解壓 tar
import org.apache.commons.compress.archivers.tar.TarArchiveEntry;
import org.apache.commons.compress.archivers.tar.TarArchiveInputStream;
import org.apache.commons.compress.compressors.gzip.GzipCompressorInputStream;
import org.apache.commons.compress.utils.IOUtils;
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;
import org.springframework.stereotype.Service;
import org.springframework.util.CollectionUtils;
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
// tar.gz 文件路徑
String sourcePath = "D:\\daleyzou.tar.gz";
// 要解壓到的目錄
String extractPath = "D:\\test\\daleyzou";
File sourceFile = new File(sourcePath);
// decompressing *.tar.gz files to tar
TarArchiveInputStream fin = new TarArchiveInputStream(new GzipCompressorInputStream(new FileInputStream(sourceFile)));
File extraceFolder = new File(extractPath);
TarArchiveEntry entry;
// 將 tar 文件解壓到 extractPath 目錄下
while ((entry = fin.getNextTarEntry()) != null) {
if (entry.isDirectory()) {
continue;
}
File curfile = new File(extraceFolder, entry.getName());
File parent = curfile.getParentFile();
if (!parent.exists()) {
parent.mkdirs();
}
// 將文件寫出到解壓的目錄
IOUtils.copy(fin, new FileOutputStream(curfile));
}
