Morphia@版本不起作用

Question

我使用的是morphia 0.109，并定义了一个基类，如下所示：

@Entity
public abstract class MorphiaData {
    @Id protected ObjectId objectId;
    @Version private Long mongodocversion;
}

和预期的Morphia实体

public class ItemTest extends MorphiaData {
    public Long testValue;
}

{
    "_id" : ObjectId("54d26ed66aca89c0717e8936"),
    "className" : "test.ItemTest",
    "testValue" : NumberLong(1423077078)
}

@Entity
class MyClass {
   ...
   @Version Long v;
}

null

编辑以添加：我正在使用的保存过程：

DBObject document = MongoDbFactory.getMorphia().toDBObject(this);

DB db = MongoDbFactory.getClient();
DBCollection coll = db.getCollection(noSqlCollection.toString());

if (this.objectId != null) {
    //This is an update
    BasicDBObject searchQuery = new BasicDBObject().append("_id", this.objectId);
    coll.update(searchQuery, document);
} else {
    //This is just an add
    coll.insert(document);
    this.objectId = (ObjectId)document.get( "_id" );
}
