SpringBoot自动装配
Spring Boot自动配置主要是@EnableAutoConfiguration实现的，@EnableAutoConfiguration注解导入AutoConfigurationImportSelector类,通过selectImports方法调用SpringFactoriesLoader.loadFactoryNames()扫描所有含有META-INF/spring.factories文件的jar包，将spring.factories文件中@EnableAutoConfiguration对应的类注入到IOC容器中
注解链路
@SpringBootApplication

@EnableAutoConfiguration
=>
@EnableAutoConfiguration
=>
@Import(AutoConfigurationImportSelector.class)
=>
getAutoConfigurationEntry:122, AutoConfigurationImportSelector (org.springframework.boot.autoconfigure)
