스프링 : FrameWork : 작업틀

: 자바프로그램은 spring

DI : 의존적 관계 .. 객체를 외부파일 (.xml)에 가져옴

데이터베이스 : 오라클 -> 마이바티스 이용

                        타일즈 : 

환경설정이 필요해서 .. 필요한 라이브러리를 공급

 

스프링은 의존적주입(DI) => 외부에서 자료를 가져옴

1. XML 파일에서 가져오는 방식

  - 생성자

  - Setter

2. 자바 파일에서 가져오는 방식 ... 클래스와 메소드 구성

 * 클래스는 반드시 @Configuration 으로 어노테이션

 * 메소드는 반드시 @Bean 으로 어노테이션

 

Spring에서 자료 전송 3가지

1. Model

2. Model and View

3. Command
