##### 스프링 config.java 파일을 분리

- Standard한 방법은 기능별로 구별하는 것이다.

- ctx 선언 방법이 여러가지가 있다. 본인은 첫번째 방법이 눈에 보기 좋아 선호한다.
    1. 모든 Config를 배열 형태로 표시
    ```java
            AnnotationConfigApplicationContext ctx =
                    new AnnotationConfigApplicationContext(MemberConfig1.class, MemberConfig2.class, MemberConfig3.class);
    ```

    2. 한 config에 `@Import` 사용
    ```java
    @Configuration
    @Import({MemberConfig2.class, MemberConfig3.class})
    public class MemberConfig1 {
        (...)
    ```

- `MemberConfig1.java` 파일  
```java
package ems.member.configration;
