“@SpringBootApplication annotation
is equivalent to using @Configuration @EnableAutoConfiguration @ComponentScan”
@SpringBootApplication = @Configuration + @EnableAutoConfiguration + @ComponentScan
- @Configuration tags the class as a source of bean definitions for
the application context.
- @EnableAutoConfiguration tells Spring Boot to start adding beans based on
class path settings, other beans, and various property settings.
- @ComponentScan tells Spring to look for other components,
configurations, and services in the base package.
