Unable to save objects with LocalDateTime fields [DATACOUCH-263]

[spring-projects-issues]

Eduard Dudar opened DATACOUCH-263 and commented

1. Plain attempt to save LocalDateTime leads to the field is saved as nested object and it can not be read back because of "MappingException: No property null found on entity class java.time.LocalDateTime to bind constructor parameter to!"

2. After adding Jsr310Converters.getConvertersToRegister() to CustomConversions same exception as in DATACOUCH-55 happens

3. After adding DateConverters.getConvertersToRegister() to CustomConversions still the same exception as in DATACOUCH-55 happens

4. After defining custom LocalDateTime <-> Date <-> Number converters it finally works.

@WritingConverter
public static class LocalDateTimeToLongConverter implements Converter<LocalDateTime, Long> {
    public Long convert(LocalDateTime source) {
        return DateConverters.DateToLongConverter.INSTANCE.convert(
                Jsr310Converters.LocalDateTimeToDateConverter.INSTANCE.convert(source));
    }
}

@ReadingConverter
public static class LongToLocalDateTimeConverter implements Converter<Long, LocalDateTime> {
    public LocalDateTime convert(Long source) {
        return Jsr310Converters.DateToLocalDateTimeConverter.INSTANCE.convert(
                DateConverters.NumberToDateConverter.INSTANCE.convert(source));
    }
}
