Springboot原理初探

getAutoConfigurationEntry获取自动配置的实体

getCandidataConfiguration获取候选的配置&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; protected&nbsp;Class&lt;?&gt;&nbsp;getSpringFactoriesLoaderFactoryClass()&nbsp;{<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return&nbsp;EnableAutoConfiguration.class;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp;标注了EnableAutoConfiguration的注解的类，，，就是主启动类

public&nbsp;static&nbsp;List&lt;String&gt;&nbsp;loadFactoryNames(Class&lt;?&gt;&nbsp;factoryType,&nbsp;@Nullable&nbsp;ClassLoader&nbsp;classLoader)<br>获取所有的加载配置

loadSpringFactories(@Nullable&nbsp;ClassLoader&nbsp;classLoader)
