Next, we will briefly introduce how to use idea to create a new SpringBoot project.

@ SpringBootApplication= (default property) @ Configuration+@EnableAutoConfiguration+@ComponentScan.

1. @ Configuration: when you mention @ Configuration, you mention his partner @ Bean. Using these two annotations, you can create a simple spring configuration class that can be used to replace the corresponding xml configuration file.

The annotated class of @ Configuration identifies that this class can use the SpringIoC container as the source of the bean definition. The @ Bean annotation tells Spring that an annotated method with @ Bean will return an object that should be registered as a bean in the context of the Spring application.

2. @ EnableAutoConfiguration: can automatically configure the context of spring and try to guess and configure the bean class you want, usually automatically according to your classpath and your bean definition.

3. @ ComponentScan: automatically scans all classes marked @ Component under the specified package and registers them as bean, including the subannotation @ Service,@Repository,@Controller under @ Component.
