Class RequestPartMethodArgumentResolver

All Implemented Interfaces:

public class RequestPartMethodArgumentResolver extends AbstractMessageConverterMethodArgumentResolver
Resolves the following method arguments:

When a parameter is annotated with @RequestPart, the content of the part is passed through an HttpMessageConverter to resolve the method argument with the 'Content-Type' of the request part in mind. This is analogous to what @RequestBody does to resolve an argument based on the content of a regular request.

When a parameter is not annotated with @RequestPart or the name of the part is not specified, the request part's name is derived from the name of the method argument.

Automatic validation may be applied if the argument is annotated with any annotations that trigger validation. In case of validation failure, a MethodArgumentNotValidException is raised and a 400 response status code returned if the DefaultHandlerExceptionResolver is configured.
