IOUtils.copy介绍

[英]Copy bytes from an InputStream to an OutputStream.

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

Large streams (over 2GB) will return a bytes copied value of -1 after the copy has completed since the correct number of bytes cannot be returned as an int. For large streams use the copyLarge(InputStream, OutputStream) method.
[中]将字节从InputStream复制到OutputStream。
此方法在内部缓冲输入，因此无需使用BufferedInputStream。
复制完成后，大数据流（超过2GB）将返回字节复制值-1，因为无法将正确的字节数作为整数返回。对于大数据流，请使用copyLarge(InputStream, OutputStream)方法。
