In my application, we were using Spring Boot 2.1.6.Release. And in one of the application classes, we have auto wired- MongoMappingContext class. When I run the app, it works fine and autowiring happens. Now I upgraded the Spring Boot version to 2.2.6.Release. Now when I start the app, the autowiring of the class MongoMappingContext starts failing.

@srchaitanya it is very hard to give you support with the information that you've provided. I suppose that "start failing" means that the bean is not found but perhaps that's something else entirely. You could run your application in debug mode to look at the auto-configuration report and find out why MongoMappingContext wasn't created.
If that doesn't help and you want support, please share a small sample that reproduces the problem. You can do so by attaching a zip to this issue or sharing the link to a GitHub repository.

My apologies for wrongly raising the issue. There is no issue with MongoMappingContext. There was a Maven issue in my PC and that lead me to believe that the auto-wiring issue with MongoMappingContext. After maven issue is fixed, I tried again, and found no auto-wiring issue.
