I'm wondering, is there any example how to properly configure embedded MongoDB with Spring Boot?

For example, this is how i configure H2 embedded database:

Even run one test you need more than 1 minute:

• Startup for embed Mongo ~1 minute
• test execution ~3-8 seconds

I can't understand what is the reason for such behaviour?

I am trying to test a simple SpringBoot application with Embedded Mongo but my repository is getting set to null. Can anyone spot what I am missing?

//Controller:

I need to embed Mongodb to Spring Boot application. But the way how I've done it leads to re-creating mongo db every time I start app. I mean, my documents don't save to database persistently.

Every start I see in logs:

I hope someone can help me.

My problem: I want to create a web backend with spring-boot, which supports REST. For POST-Request, it must accept JSON and XML.
