1) 파일 이름 : 04-SpringParameterObject
2) 앞에서 사용한 기본적인 파일
1. com.heeyeon.config -> package
① . RootAppContext.java
② . ServletAppContext.java
③ . SpringConfigClass.java
2. com.heeyeon.controller -> package
① . HomeController.java
3. com.heeyeon.model
① . DataBean 만들예정
3) 파일 자체에 pom.xml 넣기
설치하기
좋은점 - Bean 만들때 Getters and Setters 그거 안해도 되고 @Data하나면 끄읕
Project Lombok

설치했다는 가정하에
