java.lang.Objectorg.springframework.util.FileCopyUtils
public abstract class FileCopyUtils
Simple utility methods for file and stream copying. All copy methods use a block size of 4096 bytes, and close all affected streams when done.
Mainly for use within the framework, but also useful for application code.
