import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

Indicates one or more @Configuration classes to import.

Provides functionality equivalent to the <import/> element in Spring XML. Allows for importing @Configuration classes, ImportSelector and ImportBeanDefinitionRegistrar implementations, as well as regular component classes (as of 4.2; analogous to AnnotationConfigApplicationContext.register).

@Bean definitions declared in imported @Configuration classes should be accessed by using @Autowired injection. Either the bean itself can be autowired, or the configuration class instance declaring the bean can be autowired. The latter approach allows for explicit, IDE-friendly navigation between @Configuration class methods.

May be declared at the class level or as a meta-annotation.

If XML or other non-@Configuration bean definition resources need to be imported, use the @ImportResource annotation instead.
