问题
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?
回答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
