@Configuration
public class WebConfig implements WebMvcConfigurer {
    @Bean

        GsonBuilder b = new GsonBuilder();
        b.registerTypeAdapterFactory(HibernateProxyTypeAdapter.FACTORY);

        b.registerTypeAdapterFactory(LocalDateTypeAdapter.FACTORY);
        b.registerTypeAdapterFactory(LocalDateTimeTypeAdapter.FACTORY);
        return b.create();
    }

        stringConverter.setSupportedMediaTypes(Collections
            .singletonList(MediaType.TEXT_PLAIN));

            .asList(MediaType.APPLICATION_JSON));
        converters.add(gsonHttpMessageConverter);
    }
