Missing setter for connectionStringSource in MongoDb4Provider

[ihordz]

Description

It's no way to create MongoDb4Provider programmatically. Setter for connectionStringSource is missing in Builder.

Configuration

Version: 2.14.0+ (From the first version when MongoDB 4 support was added)

Thanks so much for the report and the PR @ihordz, much appreciated! I will merge them momentarily.

You are both right and wrong. You're right that MongoDb4Provider indeed doesn't expose connectionStringSource in its builder. That said, you don't (and shouldn't!) need that for programmatic configuration. You shouldn't be using the MongoDb4Provider class directly, but rather be accessing it via AppenderComponentBuilder. See the programmatic configuration guide for details.

As a matter of fact, by accessing the classes directly rather than using the configuration API, you are walking on thin ice. Log4j crew strives to provide backward compatibility at the API (i.e., log4j-api) and configuration level, though we are not that strict when it comes to the implementation (i.e., log4j-core) itself. Hence, I strongly advise you to always stick to the configuration API for programmatic configuration.

Thank you @vy for quick merge and good advice.
