方法详细资料

transferTo

public void transferTo(File dest)
                throws IOException

从接口复制的说明: MultipartFile

Transfer the received file to the given destination file.

This may either move the file in the filesystem, copy the file in the filesystem, or save memory-held contents to the destination file. If the destination file already exists, it will be deleted first.

If the target file has been moved in the filesystem, this operation cannot be invoked again afterwards. Therefore, call this method just once in order to work with any storage mechanism.

NOTE: Depending on the underlying provider, temporary storage may be container-dependent, including the base directory for relative destinations specified here (e.g. with Servlet multipart handling). For absolute destinations, the target file may get renamed/moved from its temporary location or newly copied, even if a temporary copy already exists.

指定者:

transferTo 在接口中 MultipartFile

参数:

dest - the destination file (typically absolute)

抛出:

IOException - in case of reading or writing errors
