类 DefaultFileRenamer

public class DefaultFileRenamer
extends FileRenamer

Implements a renaming policy that adds increasing integers to the body of any file that collides. For example, if foo.gif is being uploaded and a file by the same name already exists, this logic will rename the upload foo1.gif. A second upload by the same name would be foo2.gif. Note that for safety the rename() method creates a zero-length file with the chosen name to act as a marker that the name is taken even before the upload starts writing the bytes.
