Answer 1

You can (and probably should) you RepositoryRestConfigurerAdapter (in Spring Data Rest 2.4) or RepositoryRestMvcConfiguration which expose the configureObjectMapper method.

@Configuration
class RepositoryRestAdapterConfiguration extends RepositoryRestConfigurerAdapter {

    @Override
    public void configureJacksonObjectMapper(ObjectMapper objectMapper) {
        objectMapper.registerModule(new JavaTimeModule());
        objectMapper.disable( SerializationFeature.WRITE_DATES_AS_TIMESTAMPS );
    }

}
