Spring Data Rest and java.time serialization

I've a project without Spring Boot, but it uses some spring modules like "spring data" and "spring data rest".

I've some problem with the serialization of the java.time.* fields. I've found some tutorials like this but even if I add the following dependency

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>${jackson.version}</version>
</dependency>

and the following code in my RepositoryRestConfigurerAdapter

@Component public class CvlRepositoryRestConfigurerAdapter extends RepositoryRestConfigurerAdapter {

@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    config.setDefaultPageSize(75);
    config.setReturnBodyForPutAndPost(Boolean.TRUE);
}

@Override
public void configureJacksonObjectMapper(ObjectMapper objectMapper) {
    super.configureJacksonObjectMapper(objectMapper);
    objectMapper.configure(SerializationFeature.WRITE_DATE_KEYS_AS_TIMESTAMPS, false);
}

}

my actual response regarding a java.time field is like the following

"rateDate" : { "year" : 2017, "month" : "FEBRUARY", "dayOfMonth" : 14, "dayOfWeek" : "TUESDAY", "era" : "CE", "dayOfYear" : 45, "leapYear" : false, "monthValue" : 2, "chronology" : { "id" : "ISO", "calendarType" : "iso8601" }

What I'm doing wrong? What I'm forgetting?

here my adapter. Now it's working

@Component
public class CvlRepositoryRestConfigurerAdapter extends RepositoryRestConfigurerAdapter {

@Override
public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
    config.setDefaultPageSize(75);
    config.setReturnBodyForPutAndPost(Boolean.TRUE);
}

@Override
public void configureJacksonObjectMapper(ObjectMapper objectMapper) {
    super.configureJacksonObjectMapper(objectMapper);
    objectMapper.configure(SerializationFeature.WRITE_DATE_KEYS_AS_TIMESTAMPS, false);
    SimpleModule sm = new SimpleModule("jsr310module");
    sm.addSerializer(LocalDate.class,new LocalDateSerializer(DateTimeFormatter.ISO_DATE));
    sm.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ISO_DATE));
    sm.addSerializer(LocalDateTime.class,new LocalDateTimeSerializer(DateTimeFormatter.ISO_DATE_TIME));
    sm.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ISO_DATE_TIME));
    objectMapper.registerModule(sm);
}

}

I only need to check for timezone(ZonedDateTime fields) and encoding(seems to be UTF-8 is the default) and all will be fine. Hope to be useful for someone else
