Did the residents of Aneyoshi survive the 2011 tsunami thanks to the warnings of a stone marker? So by default, the Spring Boot configuration will be as follows: Lets start with a quicker example by implementing the same. readValue(byte[] src, Class valueType), The readValue() and its variations are used to de-serialize JSON content, readValues(JsonParser p, Class valueType). The WRITE_DATES_AS_TIMESTAMPS feature defines whether you'd like to write the date field as a numeric timestamp or as another type. Last step is the use the model mapper to convert the one object to another object. On the other hand, you might want to force response solidarity within a project - to standardize the data being transmitted between APIs, instead of Jackson silently ignoring properties if they're (erroneously) changed. canDeserialize(JavaType type, AtomicReference cause). It is an overridable helper method that is used to construct SerializerProvider. This is easily avoided by setting the @JsonProperty annotation: Now both when serializing and deserializing, the snake case would be enforced, and no issues arise between the POJO and incoming JSON.
