java中解压tar.gz文件

1、maven 中引入 apache 解压 / 压缩 工具类

<!-- 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、代码中使用

（1）将 tar.gz 转换为 tar
（2）解压 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 文件路径
        String sourcePath = "D:\daleyzou.tar.gz";
        // 要解压到的目录
        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;
        // 将 tar 文件解压到 extractPath 目录下
        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();
            }
            // 将文件写出到解压的目录
            IOUtils.copy(fin, new FileOutputStream(curfile));
        }
