@Souciance Eqdam Rashti Я понимаю это. Можете ли вы предоставить код Java?
я есть pojo, как это:
@Document(collection = "data")
public class DataPoint {
@Id
private String id;
private LocalDateTime createdDate;
....
}
в некоторой кодовой базе у меня есть следующий код:
@Autowired
private ProducerTemplate producerTemplate;
...
final List<DataPoint> dataPoints =....
producerTemplate.sendBody("mongodb:mongoBean?database=" + mongoDataConfiguration.getDatabase()
+ "&createCollection=true&operation=insert&collection=" + mongoDataConfiguration.getDataPointCollection(),
dataPoints);
Но когда я открываю коллекцию в базе данных, я вижу поле даты следующим образом:
"createdDate" : {
"month" : "NOVEMBER",
"year" : 2017,
"dayOfMonth" : 7,
"dayOfWeek" : "TUESDAY",
"dayOfYear" : 311,
"monthValue" : 11,
"hour" : 17,
"minute" : 55,
"nano" : 259000000,
"second" : 21,
"chronology" : {
"id" : "ISO",
"calendarType" : "iso8601"
}
Но я хочу хранить обычную дату ISO, узнаваемую для mongoDB. Это должно быть что-то вроде этого:
ISODate("2017-11-06T12:47:51.720")
1:
Я читаюЭта тема:
Таким образом, я создал собственный сериализатор:
public class IsoDateSerializer extends JsonSerializer<DateTime> {
@Override
public void serialize(DateTime value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
jgen.writeStartObject();
serializeContents(value.toDate(), jgen, provider);
jgen.writeEndObject();
}
private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
jgen.writeFieldName("$date");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
String formattedDate = formatter.format(value);
jgen.writeString(formattedDate);
}
}
и правильно зарегистрировал:
@JsonSerialize(using = IsoDateSerializer.class)
public DateTime getCreatedDate() {
return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC)));
}
Но это исключение:

Тогда мне нужно написать:
.marshal(jackson)
.convertBodyTo(String.class)
но выглядит какproducerTemplate не имеет соответствующего API.
Хорошо, я понимаю причину исключения. @Нил Ланн сказал, что это потому, что имена начались с$ - зарезервированный.
В соответствии @Нил Ланн советы, которые я пытался сделать
а) Дата возврата в модели:
public DateTime getCreatedDate() {
return new DateTime(Date.from(createdDate.toInstant(ZoneOffset.UTC))).toDate();
}
Это привело к сохранению даты как NumberLong
б) пытался изменить$date с участиемmyDate в сериализаторе, но это приводит к сохранению даты в виде обычной строки
с)
Также я попытался изменить формат даты в сериализаторе в соответствии с @Нил Ланн совет в предыдущем вопросе:
private void serializeContents(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
jgen.writeFieldName("mydate");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
String formattedDate = formatter.format(value);
jgen.writeString("ISODate(" +formattedDate + ")");
}
Но это все еще не работает, и я вижу:
"createdDate" : {
"mydate" : "ISODate(2017-11-08T13:15:06)"
},
в монго-оболочке
Пожалуйста, помогите бороться с этим вопросом?
Постскриптум
Когда я использую данные весны - дата хранит прямо сейчас без дополнительных движений
