ImportSelector代码原文翻译

/**
 * Interface to be implemented by types that determine which @{@link Configuration}
 * class(es) should be imported based on a given selection criteria, usually one or
 * more annotation attributes.
 * ImportSelector的子类应该基于给定的选择规则来判定什么样的配置类应该被导入
 * 这样规则通常是一个或多个注解属性
 *
 * <p>An {@link org.springframework.context.annotation.ImportSelector} may implement any of the following
 * {@link org.springframework.beans.factory.Aware Aware} interfaces,
 * and their respective methods will be called prior to {@link #selectImports}:
 * 任何ImportSelector的实现类都可以实现以下接口
 * 并且他们相应的方法会优先于selectImports被调用
 * <ul>
 * <li>{@link org.springframework.context.EnvironmentAware EnvironmentAware}</li>
 * <li>{@link org.springframework.beans.factory.BeanFactoryAware BeanFactoryAware}</li>
 * <li>{@link org.springframework.beans.factory.BeanClassLoaderAware BeanClassLoaderAware}</li>
 * <li>{@link org.springframework.context.ResourceLoaderAware ResourceLoaderAware}</li>
 * </ul>
 *
 *
 * <p>{@code ImportSelector} implementations are usually processed in the same way
 * as regular {@code @Import} annotations, however, it is also possible to defer
 * selection of imports until all {@code @Configuration} classes have been processed
 * (see {@link DeferredImportSelector} for details).
 *
 * Spring对ImportSelector的处理方式和普通的@Import注解的处理方式是一样的，
 * 但是ImportSelector可以在选择如何导入配置类上做差异化处理
