What is spring boot starter project
—————————————————
Whenever you are building any spring boot app the first thing that you need is the “ What is spring boot starter project “. This helps you getting all the required jars that you will be needing for your projects. For an example a What is spring boot starter web dependency can get you all the jars that you need to develop a web application in java spring.


What is spring boot starter parent
—————————————————
Spring boot starter parent can help you manage the versions for all the dependency that you are having inside your app. It can even manage the version of your java projects and third party library and even help you to load the application.properties file without any configuration.

The @Component scan help you to detect all the classes annotated with @Controller / @RestController / @Repository / @Controller and help us creating objects (beans) on our behalf. Spring stores all these beans inside a spring container called “IOC container”. Spring’s Application Context / AnnotationConfigApplicationContext represents the IOC container.

The Container creation in Spring Boot is taken care by SpringApplicaiton class run().

The run() internally creates an application context for us. The run() can sense what kind of application we are building . For an example is it a web/REST API/standalone / batch / reactive application and accordingly can help us creating an ApplicationContext.
