Jackson Object Mapper in spring MVC not working

Question

Every object with Date format is being serialized as a long.

I\'ve read around that I need to create a custom object mapper

and so I did:

pub         


        

Answer 1

Try adding 0 as index in #add()

@Configuration
@ComponentScan()
@EnableWebMvc
@PropertySource("classpath:/web.properties")
public class WebConfig extends WebMvcConfigurerAdapter
{

    @Override
    public void configureMessageConverters(final List> converters)
    {
        converters.add(0, jsonConverter());
    }

    @Bean
    public MappingJacksonHttpMessageConverter jsonConverter()
    {
        final MappingJacksonHttpMessageConverter converter = new MappingJacksonHttpMessageConverter();
        converter.setObjectMapper(new CustomObjectMapper());

        return converter;
    }
}

It worked for me.
