Anda perlu membuat codec khusus untuk Bulan Tahun karena ini bukan tipe Bson standar. Ini melibatkan dua langkah. Sesuaikan berdasarkan kebutuhan Anda.
Buat codecnya
public class YearMonthCodec implements Codec<YearMonth> {
public void encode(BsonWriter writer, YearMonth value, EncoderContext encoderContext) {
writer.writeStartDocument();
writer.writeName("year");
writer.writeInt32(value.getYear());
writer.writeName("month");
writer.writeInt32(value.getMonth().getValue());
writer.writeEndDocument();
}
public Class<YearMonth> getEncoderClass() {
return YearMonth.class;
}
public YearMonth decode(BsonReader reader, DecoderContext decoderContext) {
reader.readStartDocument();
int year = reader.readInt32("year");
int month = reader.readInt32("month");
reader.readEndDocument();
return YearMonth.of(year, month);
}
}
Daftarkan codec dengan klien Mongo
CodecRegistry codecRegistry = CodecRegistries.fromRegistries(CodecRegistries.fromCodecs(new YearMonthCodec()),
MongoClient.getDefaultCodecRegistry());
MongoClientOptions options = MongoClientOptions.builder().codecRegistry(codecRegistry).build();
MongoClient mongoClient = new MongoClient(new ServerAddress(), options);
