The @SpringBootApplication contains three useful annotations, including@SpringBootConfiguration: Look at the source code is actually @configuration, indicating that the current class is a configuration class, like an XML configuration file, and now is a Java configuration file, the effect is the same, generally with @bean.@EnableAutoConfiguration: Enable automatic configuration of the Spring application context to try to guess and configure the beans

Many spring boot developers always use @configuration, @EnableAutoConfiguration and @ComponentScan annotate their main class.

Use the "default" package When a class does not contain a package declaration, it is considered to be under the default package. It is not generally recommended to use default package and should be avoided. Because classes from each jar will be read for spring boot applications that use @componentscan, @EntityScan or @
