java - 使用nio写入GZIP文件

Question

这是我的代码:

WritableByteChannel channel = null;
GZIPOutputStream out = null;
try {
     channel = Channels.newChannel(new FileOutputStream("C:\\temp\\111.zip"));

     out = new GZIPOutputStream(Channels.newOutputStream(channel));
    for (long i = 0; i < 10000000000; i++) {    
       out.write(("string" + i + "\n").getBytes());
     } 

   } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (channel != null) {
                channel.close();
            }
        } catch (Exception e) {
        }
        try {
            if (out != null) {
                out.close();
            }
        } catch (Exception e) {
        }
    }    }

我得到了 zip，但它的内容已损坏。

我会这样做:

GZIPOutputStream gzipOS = new GZIPOutputStream(new FileOutputStream("C:\\temp\\111.gz"));
WritableByteChannel out = Channels.newChannel(gzipOS);

并且只需使用out.write()即可使用NIO进行写入。不要忘记稍后关闭资源。
