Why does Spring Boot refresh the context right after preparing the context

I am reading the source code of Spring Boot and I found that Spring Boot refreshes the context right after preparing the context in the run method.

SpringApplication.run method:

...
prepareContext(context, environment, listeners, applicationArguments,printedBanner);
refreshContext(context);
...

Can anyone explain why refreshing context is needed? Thanks.

Because refreshContext causes context initialization/reinitialization, such as invoking BeanFactoryPostProcessor beans, registering listeners, initilizing message source etc. You can see it in sources of the AbstractApplicationContext#refresh method.

Here you can find an article about Spring internals and refresh process.
