Spring Boot Notes 1.0v

	Spring Boot Notes

	@Component vs @Bean

	The @Bean annotation is a method-level annotation, whereas @Component is a class-level annotation.

	The @Component annotation doesn't need to be used with the @Configuration annotation, whereas the @Bean generic annotation has to be used within a class annotated with @Configuration.


	If your component doesn't need to communicate with a database or return an HTTP result, you can use the @Service annotation whenever using the @Component annotation is possible.
