www-url-form-encoded parameters are not handed in Spring project

[guskim-nsuslab]

Hi,

First, I'm really enjoying the logbook library and thank you for your effort.

I'm not sure the issue I experienced is a bug or intended behavior, and would like to say sorry if it's not a bug.

Description

I'm building a project using Spring Boot 2.4.1 with logbook-spring-boot-starter version: 2.4.1.

One of my controller methods is defined like below.

@RequestMapping(path = "/xxx/xxx", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public ResponseObject method(final RequestObject req) 

When I sent requests to the API with x-www-url-form-encoded parameters, req parameter was always null before I changed logbook.filter.form-request-mode to parameter.

Expected Behavior

Request parameters need to be handed to target methods with the default option(body)
