How can I upsert data into mongodb collection with java-driver?
I try (with empty collection):
db.getCollection(collection).update(new BasicDBObject("_id", "12"), dbobject, true, false);
But document was created with _id == ObjectID(...). Not with "12" value.
This code (js) add document with _id = "12" as expected
db.metaclass.update(
{ _id:12},
{
$set: {b:1}
},
{ upsert: true }
)
mongo-java-driver-2.11.2
If you are using mongo-java driver 3, following .updateOne()
method with {upsert, true}
flag works.
void setLastIndex(MongoClient mongo, Long id, Long lastIndexValue) {
Bson filter = Filters.eq("_id", id);
Bson update = new Document("$set",
new Document()
.append("lastIndex", lastIndexValue)
.append("created", new Date()));
UpdateOptions options = new UpdateOptions().upsert(true);
mongo.getDatabase(EventStreamApp.EVENTS_DB)
.getCollection(EventCursor.name)
.updateOne(filter, update, options);
}
