    It can be achieved by using a custom HttpMessageConverter and defining a custom content-type which can be anything other than standard (I used application/mjson):

    MHttpMessageConverter.java

    public class MHttpMessageConverter implements HttpMessageConverter{
    @Override
    public boolean canRead(Class aClass, MediaType mediaType) {
        if (mediaType.getType().equalsIgnoreCase("application")
                && mediaType.getSubtype().equalsIgnoreCase("mjson"))
            return true;
        else
            return false;
    }

    @Override
    public boolean canWrite(Class aClass, MediaType mediaType) {
        return false;
    }

    @Override
    public List getSupportedMediaTypes() {
        return new ArrayList<>(Arrays.asList(MediaType.APPLICATION_JSON));
    }

    @Override
    public Object read(Class aClass, HttpInputMessage httpInputMessage) throws IOException, HttpMessageNotReadableException {
        ObjectMapper mapper = new ObjectMapper();
        Object obj = mapper.readValue(httpInputMessage.getBody(),aClass);
        return obj;
    }

    @Override
    public void write(Object o, MediaType mediaType, HttpOutputMessage httpOutputMessage) throws IOException, HttpMessageNotWritableException {

    }
}



    CustomRestConfiguration.java
    


    @Configuration
public class CustomRestConfiguration extends RepositoryRestConfigurerAdapter {

    @Override
    public void configureHttpMessageConverters(List> messageConverters) {
        messageConverters.add(new MHttpMessageConverter());
    }
}
