ZonedDateTime 与 MongoDB

试着用ZonedDateTime和MongoDB.我能在MongoDB中存ZonedDateTime，但当我看记录时，里面有太多不必要的东西:

> "timestamp" : {
>             "dateTime" : ISODate("2016-12-13T13:45:53.991Z"),
>             "offset" : {
>                 "_id" : "-05:00",
>                 "totalSeconds" : -18000
>             },
>             "zone" : {
>                 "_class" : "java.time.ZoneRegion",
>                 "_id" : "America/New_York",
>                 "rules" : {
>                     "standardTransitions" : [ 
>                         NumberLong(-2717650800)
>                     ],
>                     "standardOffsets" : [ 
>                         {
>                             "_id" : "-04:56:02",
>                             "totalSeconds" : -17762
>                         }, 
>                         {
>                             "_id" : "-05:00",
>                             "totalSeconds" : -18000
>                         }
>                     ],
>                     "savingsInstantTransitions" : [ 
>                         NumberLong(-2717650800), 
>                         NumberLong(-1633280400), 
>                         NumberLong(-1615140000), 
>                         NumberLong(-1601830800), 
>                         NumberLong(-1583690400), 
>                         NumberLong(-1570381200),
> and so on....

此外，当我试图检索同一日期时，它会给我以下信息:

> org.springframework.data.mapping.model.MappingException: No property
> null found on entity class java.time.ZonedDateTime to bind constructor
> parameter to!

我和LocalDateTime人一起工作时没有这个问题.

UPDATE:

public class ZonedDateTimeToLocalDateTimeConverter implements Converter<ZonedDateTime, LocalDateTime> {
    @Override
    public LocalDateTime convert(ZonedDateTime source) {
        return source == null ? null : LocalDateTime.ofInstant(source.toInstant(), ZoneId
                .systemDefault());
    }
}

和

public class LocalDateTimeToZonedDateTimeConverter implements Converter<LocalDateTime,
        ZonedDateTime> {
    @Override
    public ZonedDateTime convert(LocalDateTime source) {
        return source == null ? null : ZonedDateTime.of(source, ZoneId.systemDefault());
    }
}

登记如下:

@Bean
public CustomConversions customConversions(){
        List<Converter<?,?>> converters = new ArrayList<Converter<?,?>>();
        converters.add(new ZonedDateTimeToLocalDateTimeConverter());
        converters.add(new LocalDateTimeToZonedDateTimeConverter());
        return new CustomConversions(converters);
    }

@Bean
public MongoTemplate getMongoTemplate() throws UnknownHostException {
        MappingMongoConverter converter = new MappingMongoConverter(
                new DefaultDbRefResolver(getMongoDbFactory()), new MongoMappingContext());
        converter.setCustomConversions(customConversions());
        converter.afterPropertiesSet();
        return new MongoTemplate(getMongoDbFactory(), converter);
    }
