在Java中:如何从byte []数组中压缩文件？

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.zip.GZIPOutputStream;

public class ByteArrayCompressor {
    public static byte[] compress(byte[] data) throws IOException {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        GZIPOutputStream gzipOutputStream = new GZIPOutputStream(byteArrayOutputStream);
        gzipOutputStream.write(data);
        gzipOutputStream.close();
        return byteArrayOutputStream.toByteArray();
    }
}
