One of Spring Boot's most powerful features is its auto-configuration. This magic is key to the convention-over-configuration approach that has brought a massive boost in productivity to Java developers. But is it magic?

In this talk, we will walk through how auto-configuration works in detail. Features like spring.factories, @Conditional, @AutoConfigureBefore and many more.

We will take a look at how you could write a Spring Boot starter yourself and elaborate on why this might make sense for you in your current project/company.
