spring源码分析之@Import注解
Indicates one or more {@link Configuration @Configuration} classes to import.
表示一个或多个类会被导入，参考@Configuration.
Provides functionality equivalent to the {@code
提供在xml中
Allows for importing {@code @Configuration} classes, {@link ImportSelector} and {@link ImportBeanDefinitionRegistrar} implementations,as well as regular component classes (as of 4.2; analogous to {@link AnnotationConfigApplicationContext#register}).
允许加上导入类，ImportSelector和ImportBeanDefinitionRegistrar的实现,等同于正常的组件类(4.2开始;类似于AnnotationConfigApplicationContext.register).
AnnotationConfigRegistry接口是从4.1开始的
{@code @Bean} definitions declared in imported {@code @Configuration} classes should be accessed by using {@link org.springframework.beans.factory.annotation.Autowired @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 {@code @Configuration} class methods.
在导入类里定义的Bean应该可以被Autowired注入访问。bean自身或者定义bean的配置类都能被autowired。后者能在类方法之间被显式的导航.
May be declared at the class level or as a meta-annotation.
在class层级定义或者当做一个meta-annotation。
If XML or other non-{@code @Configuration} bean definition resources need to be imported, use the {@link ImportResource @ImportResource} annotation instead.
如果xml或者其他没有@Configuration的bean资源需要被导入，那就使用@ImportResource注解来替代。
