Spring 10일차 - 스프링 MVC

2020.11.09(월)

 

 

.m2

tomcat

sts-bundle(편집기)

 

클래스: 리플렉션 (클래스의 정보를 읽어와서 처리)

 

1) class : Class.forName() => 메모리 할당

2) 멤버변수 : 필요시에 변수의 초기화

3) 생성자 : 멤버변수 초기화 (매개변수)

4) 메소드 : setter/getter

 

 

DL getBean() 클래스 관리자 사용자 요청 => 클래스 찾기

 

DI 주입(필요한데이터 첨부)

=> 1) seter DI (멤버변수 값 주입)

2) 생성자 DI (생성자 매개변수에 값 주입 c:name="")

3)메소드 DI (메소드 init-method destroy-method)

 

 

<DB사용하지 않고 데이터 가져오기 => json>

SpringMovieProject

 

기본설정

1)Properties - Java Compiler, Project Facets에서 JDK 1.8로 수정

2)pom.xml 수정

3)web.xml
