Points To Remember

Add the following dependency to the gradle project.

compile('com.fasterxml.jackson.core:jackson-databind:2.7.1-1')

Read JSON in Filter and bind it to POJO class

So, in this way you can read JSON from the request and bind it to the any custom class.

How to Send Rest Response For Lazy fetched Hibernate Objects with Jackson

Just add the following class to your application and your jackson will be configured to send the JSON response for the LAZY fetched domain objects.

@Configuration
@EnableWebMvc
public class HibernateAwareObjectMapper extends WebMvcConfigurerAdapter {

    //More configuration....

    /* Here we register the Hibernate4Module into an ObjectMapper, then set this custom-configured ObjectMapper
     * to the MessageConverter and return it to be added to the HttpMessageConverters of our application*/
    public MappingJackson2HttpMessageConverter jacksonMessageConverter(){
        MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();

        ObjectMapper mapper = new ObjectMapper();
        //Registering Hibernate4Module to support lazy objects
        mapper.registerModule(new Hibernate4Module());

        messageConverter.setObjectMapper(mapper);
        return messageConverter;

    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        //Here we add our custom-configured HttpMessageConverter
        converters.add(jacksonMessageConverter());
        super.configureMessageConverters(converters);
    }

    //More configuration....

}

With this class in class path you will be able to send the rest response for the LAZY fetched Hibernate Entities.
