Being still a little unfamiliar with Spring, I have encountered a problem that makes it necessary implementing my a custom deserialzer for Jackson. The procedure is described in a small tutorial, however, I am stuck with Spring. I do not understand, where
ObjectMapper mapper = new ObjectMapper();
in Spring MVC is carried out when json is deserializes by a method of a controller class. So I do not know, what to do in order to replace the default deserializer by a custom deserialiser.
Any suggestions most welcome.
