我正在尝试使用spring webflux和postgres sql将json插入json列。我已经创建了自定义转换器的阅读和写作。问题是现有的json值变为null，每当尝试更新记录时。新的值也作为json沿着null对象一起插入。请让我知道我哪里做错了

public class ReactivePostgresConfig extends AbstractR2dbcConfiguration {
private final ObjectMapper objectMapper;

@Bean
@Override
public R2dbcCustomConversions r2dbcCustomConversions() {
    System.out.println("r2dbcCustomConversions ++++++++++++++++++");
    List<Converter<?, ?>> converters = new ArrayList<>();
    converters.add(new JsonToMapConverter(objectMapper));
    converters.add(new MapToJsonConverter(objectMapper));
    return new R2dbcCustomConversions(getStoreConversions(), converters);
}

@Override
public ConnectionFactory connectionFactory() {
    // TODO Auto-generated method stub
    return null; // configured via properties file
}

private final ObjectMapper objectMapper;
@Override

    try {

        //return AppJsonUtil.parseMessageAsList(json.toString(), SeasonsJsonDto.class);
        return Arrays.asList(objectMapper.readValue(json.toString(), SeasonsJsonDto[].class));
        
    } catch (Exception e) {
        log.error("Problem while parsing JSON: {}", json, e);
    }
    return new ArrayList<SeasonsJsonDto>();
}

    } catch (JsonProcessingException e) {

    }
    return Json.of("");
}
