Mongodb 3.0 java insertOne

Question

I'm trying to upgrade my legacy application from Java driver 2.10.1 into 3.0.0 So the insert method is changed into insertOne. but DBCollection.insert() returned the result, where I can check the getError(). But MongoCollection.insertOne() does not return a value.

How to check an error of operation?

Answer 1

You have to catch:

• MongoWriteException - if the write failed due some other failure specific to the insert command
• MongoWriteConcernException - if the write failed due being unable to fulfil the write concern
• MongoException - if the write failed due some other failure
