json Spring MVC mapping view for Google GSON?

public class AppController {
  @RequestMapping(value = "messages", produces = MediaType.APPLICATION_JSON_VALUE)
  public List<Message> getMessages() {
    // .. Get list of messages
    return messages;
public class WebConfig extends WebMvcConfigurerAdapter {
  public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
    converters.add(new GsonHttpMessageConverter());
