Using the latest release (6.1.13), when MethodArgumentTypeMismatchException happens, something like this is logged at warn level:

Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.time.OffsetDateTime'; Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.RequestParam @org.springframework.format.annotation.DateTimeFormat java.time.OffsetDateTime] for value [2024-09-09T8:30:00+02:00]]

It would be very useful to also log the name of the argument which caused the error, because sometimes there are multiple handler method arguments of the same type that are subject to the same conversion. I guess this means that error message should be put together in MethodArgumentTypeMismatchException rather than relying on TypeMismatchException (which does not have the necessary context).

Thanks for the suggestion. The message will now look like this:

"Method parameter 'paramOne': Failed to convert value of type 'java.lang.String' to required type 'java.lang.Integer'"
