java.nio.file牛逼！ public static Path move(Path source, Path target, CopyOption... options)
public enum StandardCopyOption implements CopyOption {
/**
* Replace an existing file if it exists.
*/
REPLACE_EXISTING,
/**
* Copy attributes to the new file.
*/
COPY_ATTRIBUTES,
/**
* Move the file as an atomic file system operation.
*/
ATOMIC_MOVE;
}
完美解决移动文件覆盖问题。
