public class StandardServletMultipartResolver extends Object implements MultipartResolver
MultipartResolver
interface,
based on the Servlet 3.0 Part
API.
To be added as "multipartResolver" bean to a Spring DispatcherServlet context,
without any extra configuration at the bean level (see below).
Note: In order to use Servlet 3.0 based multipart parsing,
you need to mark the affected servlet with a "multipart-config" section in
web.xml
, or with a MultipartConfigElement
in programmatic servlet registration, or (in case of a custom servlet class)
possibly with a MultipartConfig
annotation
on your servlet class. Configuration settings such as maximum sizes or
storage locations need to be applied at that servlet registration level;
Servlet 3.0 does not allow for them to be set at the MultipartResolver level.
