Char 8. 외부 파일을 이용한 설정

Enviroment 객체 이용하여 외부의 설정값을 가지고 와서 이용

어플리케이션의 기초인 ConfigurableApplicationContext로 ctx 파일 생성

2. ctx.getEnvironment을 통해 얻은 객체를 ConfigurableEnvironment에서 생성한 Environment 객체 env에 담는다.

3. env.getPropertySources();로 프로퍼티소스를 얻어와서 MutablePropertySources에서 생성한 인스턴스에 넣는다. getPropertySources();를 해주는 이유는 Environment 객체 안에는 각각의 정보를 갖고있는 PropertySources라는 객체가 있어서 다 구해옴

4. PropertySources에서 추가와 추출 가능 (추가 : addLast / 추출 : getProperty)
