스프링 프레임워크 - [Spring] 어노테이션(Annotation)

Annotation?

어노테이션은 메타데이터라고 볼 수 있다.

애플리케이션이 처리해야될 데이터가 아니라 컴파일 과정과 실행과정에서 코드를 어떻게 컴파일하고 처리할지를 알려준다.(찍어서 사용하는 일은 없음)

1. 용도

1) 컴파일러에게 코드 문법 에러를 체크하도록 정보를 제공 @Overrid

2) 소프트웨어 개발시 빌드나 배타코드를 자동으로 생성할 수 있도록 정보를 제공 (bean, aop등)

3) 실행시 특정 기능을 실행하도록 정보를 제공

2. 종류

1) 시스템 정의 어노테이션 : @Overrid @Deprecated @SupperssWarning

2) 커스텀(개발자) 어노테이션 :

2-1) 타입과 정의 - 타입, 이름, 디폴트 값

2-2) 적용 대상 - METHOD, FLED, TYPE(CLASS), 생성자, PARAMETER 등이 있다.

2-3) 유지 정책 - SOURCE, CLASS, RUNTIME

게시판 프로젝트 Annotation 사용하기

xml파일을 annotation형태로 고쳐 간단하게 바꾼다.

- 결합도를 낮추고 유지보수성을 높이기 위해 xml로 설정하였으나 xml이 너무 많아지면 오히려 유지보수성이 낮아지는 현상이 발생

- 유지보수에 중점을 맞추기 위해 시스템 전체에 영향을 주고 이후에 변경 가능성이 있는 것은 xml로 설정

SpringController-servlet.xml

<aop:aspectj-autoproxy/> 태그를 설정파일에 추가하면 @Aspect 어노테이션이 적용된 빈을 Aspect로 사용할 수 있게 된다.

context:component-scan

: @Controller, @Service, @Repository, @Component등의 어노테이션을 component-scan을 xml에 선언해서 사용함.

base-package는 패키지를 어디부터 스캔할지 지정해주는 부분. 스캔할 패키지를 여러개로 지정해 줄 수 있다.

디폴트 값으로 @Controller, @Service, @Repository, @Component로 등록된 빈을 스캔해준다.

기존 XML을 사용할 때는 HandlerMapping을 사용하였지만 이제는 context:component-scan 가 그 역할을 대신한다.

MemberController.java

@Autowired : 각 상황의 타입에 맞는 IoC컨테이너 안에 존재하는 Bean을 자동으로 주입해줌

객체의 의존성을 가지는 부분에 간단히 @Autowired어노테이션을 사용하면 쉽게 의존성 주입을 받을 수 있게 됨.

주입하려고 하는 객체의 타입이 일치하는 객체를 자동으로 주입한다.

의존객체 자동 주입?

스프링 설정 파일에서 의존 객체를 주입할 때 <constructor-org> 또는 <property>태그로 의존 대상 객체를 명시하지 않아도 스프링 컨테이너가 자동으로 필요한 의존 대상 객체를 찾아서 의존 대상 객체가 필요한 객체에 주입해 주는 기능이다.

구현방법은 @Autowired와 @Resource 어노테이션이 있다.

@Controller : 주로 View를 반환하기 위해 사용,

해당 클래스가 Controller임을 나타내기 위한 어노테이션

@RequestMapping : 요청에 대해 어떤 Controller, 어떤 메소드가 처리할지를 매핑하기 위한 어노테이션, URL을 컨트롤러의 메서드와 매핑할 때 사용하는 스프링 프레임 워크의 어노테이션

즉, 클라이언트는 URL로 요청을 전송하고 요청 URL을 어떤 메서드가 처리할지 여부를 결정하는 것

@RequestMapping이 사용하는 속성

이름	타입	설명
value	String[]	URL 값으로 매핑 조건을 부여 (default)
method	RequetMethod[]	HTTP Request 메소드 값을 매핑 조건으로 부여 사용 가능한 메소드는 GET, POST, HEAD, OPTIONS, PUT, DELETE, TRACE (7개)
params	String[]	HTTP Request 파라미터를 매핑 조건으로 부여
consumes	String[]	설정과 Content-Type request 헤더가 일치할 경우에만 URL이 호출됨
produces	String[]	설정과 Accept request 헤더가 일치할 경우에만 URL이 호출됨
