java程序如何批量解压GZIP压缩包

Answer 1

给你一段单个文件解压gzip文件代码
批量解压的话 File f = new File("要解压的文件夹目录");
String paths[] = f.list(); // 取得文件夹下的文件

然后循环调用下面的方法就可以了。

try {
// Open the compressed file
String inFilename = "infile.gzip";
GZIPInputStream in = new GZIPInputStream(new FileInputStream(inFilename));

// Open the output file
String outFilename = "outfile";
OutputStream out = new FileOutputStream(outFilename);

// Transfer bytes from the compressed file to the output file
byte[] buf = new byte[1024];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}

// Close the file and stream
in.close();
out.close();
} catch (IOException e) {
}
