Spring boot -jackson configuration

Here is My Configuration file for Jackson JSON(Faster XML) in Spring BOOT

@Bean
public MappingJackson2HttpMessageConverter jackson2Converter() {
MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
converter.setObjectMapper(objectMapper());
return converter;
}

@Bean
public ObjectMapper objectMapper() {
Object objectMapper = new ObjectMapper();
// ((ObjectMapper) objectMapper).registerModule(new Hibernate4Module());
((ObjectMapper) objectMapper)
.enable(SerializationFeature.ORDER_MAP_ENTRIES_BY_KEYS);
// to allow serialization of "empty" POJOs (no properties to serialize)
// (without this setting, an exception is thrown in those cases)
((ObjectMapper) objectMapper)
.disable(SerializationFeature.FAIL_ON_EMPTY_BEANS);
// to write java.util.Date, Calendar as number (timestamp):
((ObjectMapper) objectMapper)
.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

// DeserializationFeature for changing how JSON is read as POJOs:

// to prevent exception when encountering unknown property:
((ObjectMapper) objectMapper)
.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
// to allow coercion of JSON empty String ("") to null Object value:
((ObjectMapper) objectMapper)
.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);

return (ObjectMapper) objectMapper;
}
