DAO : Data Access Object
DTO : Data Transfer Object
DAO
-> 데이터 베이스에 접속해서 데이터 추가, 삭제, 수정 등의 작업을 하는 클래스
DTO
-> DAO 클래스를 이용하여 데이터베이스에서 데이터를 관리할 때 데이터를 일반적인 변수에 할당하여 작업 할수도 있지만 해당 데이터의 클래스를 만들어 사용
-----------------------------------------
커넥션 풀(DBCP)
-> tomcat 컨테이너가 데이터베이스 인증을 하도록 context.xml 파일을 열어 아래의 코드를 추가하낟.
ex)
이렇게 해주는데 굳이 해줘야하나 싶다. 서버를 시작한후 보면 전부다 synchronized로되어있다.
-----------------------------------------
21강
자바스크립트 – 스크립트 언어이다.
어느정도 기본적인 것은 학습을 해야한다.
jsp:forward -> jsp액션태그인데 바로 일로 가라.
-----------------------------------------
23강
EL(Expression Language)?
-> EL(Expression Language)란, 표현식 또는 액션 태그를 대신해서 값을 표현하는 언어이다.
표현식
<%= value %>
EL
${ value}
위에꺼랑 같다고 생각하면 된다.
-----------------------------------------
액션태그로 사용되는 표현식
<jsp:getProperty name="member" property="name"/>
액션태그로 사용되는 EL
${member.name }
-----------------------------------------
Model1
-> MVC에서 View와 Controller이 같이 있는 형태이다.
클라이언트(웹브라우저) -> JSP(view+Controller) -> DAO(model) ->database
