Serializing and Deserializing json in a different format. [DATAREST-614]

[spring-projects-issues]

Jack Matthews opened DATAREST-614 and commented

I need to serialize my json in http://jsonapi.org/ instead of HAL. I have tried modifying ObjectMapper by setting my own converters.

    @Bean
    public ConversionService conversionService() {
        ConversionServiceFactoryBean bean = new ConversionServiceFactoryBean();
        bean.setConverters(getConverters());
        bean.afterPropertiesSet();
        ConversionService object = bean.getObject();
        return object;
    }

    private Set<Converter> getConverters() {
        Set<Converter> converters = new HashSet<>();

        converters.add(new JsonApiSerializingConverter());
        converters.add(new JsonApiDeserializingConverter());

        return converters;
    }

but this only modifies the "content" part of the payload. It still includes a whole lot of HAL boilerplate. Is there a way to register a custom json format and scrap the HAL one completely? I am happy to do the work in integrating this format but need some pointers in the best way to approach this

A converter is not sufficient really as you need to take the Accept header and content negotiation into account. You could implement an HttpMessageConverter} (probably extending or configuring a {{MappingJackson2HttpMessageConverter) and register it on the configuration by overriding RepositoryRestMvcConfiguration.configureHttpMessageConverters(…)

Does the HttpMessageConverter have to be a subclass of MappingJackson2HttpMessageConverter? Could you simply extend AbstractHttpMessageConverter instead? I have a simple converter that writes to a tab-delimited text format, and works fine in vanilla Spring MVC, but not with Spring Data REST, even when registered in both RepositoryRestMvcConfiguration.configureHttpMessageConverters(…) and WebMvcConfigurerAdapter.configureMessageConverters(...)
