Just like @skadya's answer, I update it in new spring version and Java 8 styles.

@EnableWebMvc
@Configuration
public class WebConfig implements WebMvcConfigurer {
    private ObjectMapper mapper;

    @Autowired  // spring.jackson.* ObjectMapper's config
    public WebConfig(ObjectMapper mapper) {
        this.mapper = mapper;
    }

    @Override
    public void extendMessageConverters (List> converters) {
        converters.stream()
                .filter(x -> x instanceof  MappingJackson2HttpMessageConverter)
                .forEach(x -> ((MappingJackson2HttpMessageConverter) x).setObjectMapper(mapper));
    }
}
