Spring 数据 MongoDB 字段转换器：有什么方法可以传递参数？

Question

When our application is loading a DBOject/Document instance from our MongoDB, we need to convert all of the UTC dates in it into ZoneDateTime values using the zoneIdName, which is within the DBObject/Document instance. We have a lot of Date fields in the DBObject, so I'd like to avoid having to implement a DBOject level Spring Data MongoDB Converter.

Is it possible to use a DBOject field level Spring Data MongoDB Converter, such as the following, which uses a field in the DBObject (ie zoneIdName), to be able to perform the conversion to a ZoneDateTime? If not, I will have to implement an object-level Converter, but it will be tedious...

Thank you for your interest and time.

class ZonedDateTimeReadConverter :
    Converter<Date, ZonedDateTime> {

    override fun convert(date: Date): ZonedDateTime {
        // Need to replace "America/LosAngeles" with 
        // a value from a field in the object being processed.
        return date.toInstant().atZone(ZoneId.of("America/LosAngeles"))
    }
}

Answer 1

seems that converter for whole object is only option
