using validators in spring-data-rest returns http 500 instead of 400 [DATAREST-260]

chris opened DATAREST-260 and commented

successful (in)validated data posted results in http 500 instead of 400, from looking at the source for ValidationExceptionHandler it should return constraint violations as 400.

I have to override the validatingRepositoryEventListener bean in RepositoryRestMvcConfiguration and add each of the event validations into the listeners as follows;

@Configuration
public class RestExporterRestConfig extends RepositoryRestMvcConfiguration {

    @Bean
    public Validator validator() {
        return new LocalValidatorFactoryBean();
    }

    @Bean
    @Override
    public ValidatingRepositoryEventListener validatingRepositoryEventListener() {
        ValidatingRepositoryEventListener listener = new ValidatingRepositoryEventListener();
        configureValidatingRepositoryEventListener(listener);
        listener.addValidator("afterCreate", validator());
        listener.addValidator("beforeCreate", validator());
        return listener;
    }

}
