It is used to enable the automatic inclusion of type information. setMixInAnnotations(Map,Class> sourceMixins). Jackson can read JSON into a JsonNode instance and write JSON to JsonNode using the ObjectMapper class. By default, this functionality is turned on. I faced a problem that when you declare bean with name objectMapper in java config, just as it is showed in example, this bean is ignored by Spring Boot, cause bean with such name is already registered in the system, even if you place \@Primary annotation on it. At this point, well obtain the result which is shown below: Now in order to achieve our goal, well register a new JavaTimeModule with our custom date format: The purpose of this functional interface is to allow us to create configuration beans.
