### 36.2. 定位auto-configuration候选者
Spring Boot会检查你发布的jar中是否存在META-INF/spring.factories文件。该文件应该列出以EnableAutoConfiguration为key的配置类：
```java
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.mycorp.libx.autoconfigure.LibXAutoConfiguration,\
com.mycorp.libx.autoconfigure.LibXWebAutoConfiguration
```
如果配置需要应用特定的顺序，你可以使用[@AutoConfigureAfter](http://github.com/spring-projects/spring-boot/tree/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/AutoConfigureAfter.java)或[@AutoConfigureBefore](http://github.com/spring-projects/spring-boot/tree/master/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/AutoConfigureBefore.java)注解。例如，你想提供web-specific配置，你的类就需要应用在WebMvcAutoConfiguration后面。
