Where do I specify Jackson SerializationConfig.Feature settings in Spring 3.1

Question

I\'m puzzled as to why using a default inclusion of jackson that Spring seems to have customised the default Jackson configuration.

One setting it\'s messing with is

Starting with 3.1 M1 you can specify jackson custom configuration by registering an HttpMessageConverters through a sub-element of mvc:annotation-driven.

See Spring 3.1 MVC Namespace Improvements

See SPR-7504 Make it easier to add new Message Converters to AnnotationMethodHandlerAdapter

Exemple:

<bean id="jacksonObjectMapper" class="x.y.z.CustomObjectMapper">                
</bean>

<mvc:annotation-driven>
    <mvc:message-converters>
       <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
           <property name="objectMapper" ref="jacksonObjectMapper" />
       </bean>
       </mvc:message-converters>
</mvc:annotation-driven>

The CustomObjectMapper Object

    @Component("jacksonObjectMapper")
    public class CustomObjectMapper extends ObjectMapper {

        @PostConstruct
        public void afterPropertiesSet() throws Exception {

            SerializationConfig serialConfig = getSerializationConfig()     
                        .withDateFormat(null);

                  //any other configuration

            this.setSerializationConfig(serialConfig);
        }
    }

SerializationConfig .withDateFormat

In addition to constructing instance with specified date format, will enable or disable Feature.WRITE_DATES_AS_TIMESTAMPS (enable if format set as null; disable if non-null)
