MongoDB - Java | How to manage the connection

Question

I am using MongoDB with Java and have some problems and questions about my connection. First of all, how should I connect to Mongo? Should I use a static client and leave it

Answer 1

how should I connect to Mongo?

As it sounds, you're already using MongoClient, its a good way to go.

The MongoClient class is designed to be thread safe and shared among threads. Typically you create only 1 instance for a given database cluster and use it across your application.

Should I use a static client and leave it open?

The MongoClient instance actually represents a pool of connections to the database; you will only need one instance of class MongoClient even with multiple threads.

Do I need to explicitly close connection?

No, you don't. And that as well should resolve the error that you're getting.
