====== SpringBoot Auto Configuration ======
  * [[springframework:springboot|SpringBoot]]의 자동화된 설정을 다룬다.
  * [[https://github.com/spring-projects/spring-boot/tree/master/spring-boot-project/spring-boot-autoconfigure|spring-boot-autoconfigure]] 모듈의 소스를 참조하면 자동 설정 원리를 파악할 수 있다.
  * [[https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/resources/META-INF/spring.factories|spring.factories]]에 자동설정 Configuration 목록 있음.

===== Auto Configuration exclude =====

  * [[http://wonwoo.ml/index.php/post/1599|Spring boot configuration]]
  * ''spring.autoconfigure.exclude'' 프라퍼티를 yaml 에 지정해서 불필요한 Auto Configuration loading을 막을 수 있다.<code>
spring:
  autoconfigure:
    exclude:
      - org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration
      - org.springframework.boot.autoconfigure.data.redis.RedisRepositoriesAutoConfiguration
</code>
  * 혹은, ''@SpringBootApplication'' 애노테이션에서도 가능하다. <code java>
@SpringBootApplication(
  exclude = { RedisAutoConfiguration.class, RedisRepositoriesAutoConfiguration.class }
)
// 문자열로. FQCN 이 아니어도 되는지 여부 확인 필요.
@SpringBootApplication(
  excludeName = { "RedisAutoConfiguration", "RedisRepositoriesAutoConfiguration" }
)
</code>

===== @AutoConfigurationAfter, @AutoConfigurationBefore =====
  * 특정 Auto Configuration 실행 전후에 할 설정임을 마킹.

<code java>
@Configuration
@AutoConfigureBefore(JacksonAutoConfiguration.class)
public class SpringAutoConfiguration {
}
</code>
