如果 bootstrap 相关文件不存在，加载 application 相关文件。对应未引用 spring cloud 组件。
不过在启动过程中在扫描 classpath 下如果存在接口 ApplicationListener 的实现类，则会进行排序处理。
最终相关的配置内容加载到 AbstractApplicationContext 中的变量 environment 中进行全局配置处理。
如果同一个文件名有不同的后缀，但是配置值一致加载顺序如何？
ConfigFileApplicationListener 中逻辑如下
其中，变量值 propertySourceLoaders 通过 SpringFactoriesLoader 加载 classpath 下 META-INF/spring.factories 中 org.springframework.boot.env.PropertySourceLoader 对应的类
具体有 PropertiesPropertySourceLoader 和 YamlPropertySourceLoader。
PropertiesPropertySourceLoader 用于加载后缀为 .properties 的文件。
YamlPropertySourceLoader 用于加载后缀为 .yml 或者 .yaml 的文件。
如果对应的配置在后缀为 properties 和 yml 的文件中都存在，则 properties 优先。
ConfigFileApplicationListener 按顺序读取自动配置，在进行遍历时按序遍历，所以 properties 优先。
