Spring Boot在进行SpringApplication对象实例化时会加载META-INF/spring.factories文件，将该配置文件中的配置载入到Spring容器。

1.1.1. Maven下载源码

通过 dependency:sources 该命令可以下载该项目中所有的依赖的包的源码。

1.1.2. 源码分析

org.springframework.boot.SpringApplication：

org.springframework.core.io.support.SpringFactoriesLoader:

技术分享

由此可见，读取该配置文件来加载内容。

1.1.3. Spring.factories文件
