All Implemented Interfaces:

HandlerMethodArgumentResolver

public class RequestPartMethodArgumentResolver
extends AbstractMessageReaderArgumentResolver

Resolver for @RequestPart arguments where the named part is decoded much like an @RequestBody argument but based on the content of an individual part instead. The arguments may be wrapped with a reactive type for a single value (e.g. Reactor Mono, RxJava Single).

This resolver also supports arguments of type Part which may be wrapped with a reactive type for a single value or multiple values.
