How does Spring Boot auto configuration work internally like the @ConditionalOnClass and @ConditionalOnMissingBean?

Reveal Answer

Spring Boot scan auto configuration classes listed on the auto configurations.import file. Each class activates when the condition matches. Example ConsitionalOnClass in case a dependency is on the class path or @ConditionalOnMissingBean in case the bean is not defined.
