由以下代码抛出：

@H_403_2@final UUID id = UUID.randomUUID(); final double frequency = 8_000.0 + ( 10_000.0 * Math.random() ); final double startSec = 100*i; final double startNano = 10*i; final double endSec = startSec + ( 100*i ); final double endNano = startNano + ( 10*i ); final double latitude = ( 180.0*Math.random() ) - 90.0; final double longitude = ( 360.0*Math.random() ) - 180.0; final Document trackID = new Document( "id",new Document( "msb",id.getMostSignificantBits ()) .append( "lsb",id.getLeastSignificantBits())); final Document track = new Document( "id",id.getLeastSignificantBits())).append( "frequency",frequency ) .append( "start",new Document( "seconds",startSec ) .append( "nanoSec",startNano )).append( "end",endSec ) .append( "nanoSec",endNano )).append( "position",new Document( "latitude",latitude ) .append( "longitude",longitude )).append( "padding",new byte[1000-8-8-8-4-4-4-4-8-8] ); //_collection.insertOne( track ); _collection.updateOne( trackID,track,new UpdateOptions().upsert( true ));

注释代码_collection.insertOne(track);执行得很好.

为什么插入没有“upsert”？
