java 解决tar.gz压缩中文乱码

一时失言乱红尘 2022-10-24 11:52 223阅读 0赞

使用以下包进行tar打包的时候，如果被压缩的文件包含中文，那么压缩后会出现中文乱码

import org.apache.commons.compress.archivers.tar.TarArchiveEntry;
    import org.apache.commons.compress.archivers.tar.TarArchiveOutputStream;
    import org.apache.commons.compress.utils.IOUtils;

解决方法,使用ant:

import org.apache.tools.tar.TarEntry;
    import org.apache.tools.tar.TarOutputStream;
