Re: [morphia] Bulk insert of JavaObjects

Why not just use the save that takes your List of entities?  http://mongodb.github.io/morphia/1.1/javadoc/org/mongodb/morphia/Datastore.html#save-java.lang.Iterable-

Hello,

i'am trying to make a bulk insert with java objects. We are using the "@Version" and "@Id" annotation. Here is my code to it:

    public <E extends BasicEntity> void persist(List<E> entities) throws GeoJsonException {

        if (entities != null && !entities.isEmpty()) {

                String collectionName = entities.get(0).getClass().getAnnotation(Entity.class).value();

                BulkWriteOperation bulkWrite = mongoDatastore.getDB().getCollection(collectionName).initializeUnorderedBulkOperation();

                List<E> savedEntities = new ArrayList<>(entities.size());

                for (E ee : entities) {

                    DBObject dbObject = morphia.toDBObject(ee);

                    bulkWrite.insert(dbObject);

                    savedEntities.add((E) morphia.fromDBObject(ee.getClass(), dbObject));

                }

                try {

                    bulkWrite.execute();

                } catch (WriteConcernException e) {

                    handleWriteConcernExcpetion(e);

                }

                entities.clear(); // we have to do it "pass-by-reference-value" :(

                entities.addAll(savedEntities);

        }

    }

If I execute the code i got a "Modification" exception. However if we delete the "@Version" annotation everything themes to work. Is there a way to insert the Java Object directly (without using "morphia.toDBObject") ? 

Regards, Andy
