For all you non-xml config folks:

ObjectMapper objMapper = new ObjectMapper().setSerializationInclusion(JsonInclude.Include.NON_NULL);
HttpMessageConverter msgConverter = new MappingJackson2HttpMessageConverter(objMapper);
restTemplate.setMessageConverters(Collections.singletonList(msgConverter));
