这句话可以作为理解springboot自动注入的原理的钥匙：ImportSelector接口的selectImports返回的数组（类的全类名）都会被纳入到spring容器中.
至于spring怎么根据类名创建bean的就不用管了。博文地址https://www.jianshu.com/p/464d04c36fb1
public class AutoConfigurationImportSelector implements DeferredImportSelector, BeanClassLoaderAware, ResourceLoaderAware, BeanFactoryAware, EnvironmentAware, Ordered //看这个类实现的接口多复杂
@Override
public String[] selectImports(AnnotationMetadata annotationMetadata) {
if (!isEnabled(annotationMetadata)) {
return NO_IMPORTS;
}
AutoConfigurationMetadata autoConfigurationMetadata = AutoConfigurationMetadataLoader
.loadMetadata(this.beanClassLoader);
AutoConfigurationEntry autoConfigurationEntry = getAutoConfigurationEntry(
autoConfigurationMetadata, annotationMetadata);
return StringUtils.toStringArray(autoConfigurationEntry.getConfigurations());
}
这个方法就是导入了自动配置的文件的字符串。
