org.springframework.data.mongodb.core.MongoClientFactoryBean has been deprecated but we currently rely on it for auto-configuration.

Comment From: wilkinsona

As far as I can tell, our dependency is only for setting up dependsOn relationships between beans. Our auto-configuration creates a MongoClient without using MongoClientFactoryBean. I think we have a couple of options:

  1. Leave things as they are
  2. Ignore MongoClientFactoryBean in the dependsOn post-processors based on the assumption that it should no longer be used as it's deprecated.

I'm leaning towards 1 as, while deprecated, no replacement is offered so I think it's likely that it will continue to be used.

Sounds good. I'm wondering what we can use when MongoClientFactoryBean is actually replaced?

Comment From: wilkinsona

I'm not sure. Hopefully @christophstrobl and @mp911de can offer some guidance when the time comes.

I am wondering if that one isn't actually superseded by #19356

Comment From: wilkinsona

Yeah, I think it is. The deprecation is such that I don't think we can migrate to non-deprecated API using the current version of the driver.

Hi.

Can you tell me, when exactly it will deprecated? Currently I cannot see any signs of deprecation anywhere. I checked official documentation https://docs.spring.io/spring-data/data-mongodb/docs/current/api/org/springframework/data/mongodb/core/MongoClientFactoryBean.html nothing was mentioned about it. Moreover Visual Studio Code is quite about deprecation.

Also, after deprecation, what can I use with MongoTemplate instead of MongoClientFactoryBean?

Thank you in advance for the answer.

@DmitryN270713 It was deprecated in Spring Data 2.2 (https://docs.spring.io/spring-data/data-mongodb/docs/2.2.8.RELEASE/api/org/springframework/data/mongodb/core/MongoClientFactoryBean.html) when the factory bean produced a com.mongodb.MongoClient. It was then replaced in 3.0 with a class of the same name that produces a com.mongodb.client.MongoClient instead.
