IOUtils.copyLarge介绍

[英]Copy bytes from a large (over 2GB) InputStream to an OutputStream.

This method buffers the input internally, so there is no need to use a BufferedInputStream.

The buffer size is given by #DEFAULT_BUFFER_SIZE.
[中]将字节从较大（超过2GB）InputStream复制到OutputStream。
此方法在内部缓冲输入，因此无需使用BufferedInputStream。
缓冲区大小由#默认_buffer_size给出。
