これは、アノテーションを使用して行う方法です。

@Configuration 
public class JacksonConfiguration extends WebMvcConfigurerAdapter { 

    private final CustomObjectMapper mapper; 

    @Autowired 
    public JacksonConfiguration(CustomObjectMapper mapper) { 
     this.mapper = mapper; 
    } 

    @Override 
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) { 
     converters.add(new MappingJackson2HttpMessageConverter(mapper)); 
    } 
}
