Spring Data Redis composite key

I need to store the following class in Redis:

@Data@Builder@Accessors(chain = true)@RedisHash("Meter")public class Meter {    @org.springframework.data.annotation.Id    private Id id;    private String accountId;    private String name;    private Tags tags;    private Type type;    @Getter    @RequiredArgsConstructor    public static class Id {        private final String name;        private final String accountId;        @Override        public String toString() {            return name +":" + accountId;        }        public static Id of(String name, String accountId) {            return new Id(name, accountId);        }    }}

As you can see, it has a custom id class. The idea is that this custom key class will be represented in Redis as name:accountId. I also have a repository for this class:

public interface MeterRepository extends CrudRepository<Meter, Meter.Id> {}

When I run the project and try to use MeterRepository, I get No converter found capable of converting from type [...entity.Meter$Id] to type [java.lang.String], though I created a converter and registered it:

@Componentpublic class MeterIdToStringConverter implements Converter<Meter.Id, String> {    @Override    public String convert(Meter.Id meterId) {        return meterId.toString();    }}

@Configuration@RequiredArgsConstructorpublic class ConversionConfiguration {    private final MeterIdToStringConverter meterIdToStringConverter;    @Bean    public ConversionService conversionService(List<Converter> converters) {        final DefaultConversionService conversionService = new DefaultConversionService();        converters.forEach(conversionService::addConverter);        conversionService.addConverter(meterIdToStringConverter);        return conversionService;    }}

Moreover, I tried autowiring ConversionService and calling conversionService.canConvert(Meter.Id.class, String.class) - it returned true.

What am I doing wrong?
