code: public static File copyFile(String src, String dest, StandardCopyOption... options) throws IORuntimeException {
  		Assert.notBlank(src, "Source File path is blank !");
  		Assert.notNull(src, "Destination File path is null !");
  		return copyFile(Paths.get(src), Paths.get(dest), options).toFile();
  	}
docs: 通过JDK7+的 {@link Files#copy(Path, Path, CopyOption...)} 方法拷贝文件
  
  @param src 源文件路径
  @param dest 目标文件或目录路径，如果为目录使用与源文件相同的文件名
  @param options {@link StandardCopyOption}
  @return File
  @throws IORuntimeException IO异常
