io.github.pangju666.commons.compress.utils.GZipUtils

方法名	返回值	用途
isGZip	boolean	检查指定文件是否为有效的gzip格式
uncompress	void	解压缩gz文件
compress	void	压缩文件为gz文件

判断是否为gz文件

根据文件内容来判断文件类型，底层基于tika实现

File file = new File("file.gz");
GZipUtils.isGZip(file);

byte[] bytes = FileUtils.readFileToByteArray(file);
GZipUtils.isGZip(bytes);

InputStream inputStream = FileUtils.openInputStream(file);
GZipUtils.isGZip(inputStream);

压缩

File inputFile = new File("C:\logs");

File outputFile = new File("C:\output.gz");
GZipUtils.compress(inputFile, outputFile);

OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
GZipUtils.compress(inputFile, outputFile);

InputStream inputStream = FileUtis.openInputStream(inputFile);
OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
GZipUtils.compress(inputStream, ouputStream);

解压

File outputFile = new File("C:\logs\xxx.txt");

File inputFile = new File("C:\output.gz");
GZipUtils.uncompress(inputFile, outputFile);

OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
GZipUtils.uncompress(inputFile, ouputStream);

InputStream inputStream = FileUtils.openInputStream(inputFile);
OutputStream ouputStream = FileUtis.openOutputStream(outputFile);
GZipUtils.uncompress(inputStream, ouputStream);
