상담 게시판 (Struts2, iBatis 버전)

1. 웹 상에서 글쓰기, 글보기를 할 수 있는 프로그램.

2. 회원, 비회원 글쓰기 가능. 회원 댓글 쓰기. 회원 가입. 회원 로그인, 로그아웃.

3. 관리자 관리 기능. 관리자 답변글 쓰기.

4. 프로젝트 생성 (ConsultationStruts2_20121220)

-----------------------------------------

회원관리+성적처리 프로젝트 (Struts, iBatis 버전)

1. 성적 테이블, 회원 테이블 조인. FK 설정 필요.

2. 회원(회원번호-PK, 이름, 전화번호) -> 이전과 동일

3. 성적 (성적번호-PK, 회원번호-FK, 국어, 영어, 수학)

-> 이름 대신 회원번호-FK 설정

4. 회원에 회원 등록을 먼저하고, 성적에 성적 입력을 나중에 한다.

5. 입력, 출력, 수정, 삭제 기능을 모두 구현할 것.

----------------------------------------

CREATE TABLE member2 (

스트러츠2에서 데이터 전송 테스트(ActionSupport 클래스 이용)

* 실행순서

- struts.properties에서 인코딩 및 url 확장자 설정을 해둠.

- 사용자가 브라우저에 send01.action 입력

- struts.xml 에서 환경설정에 의해 myStruts.xml 를 실행

- myStruts.xml에서 주소창에 입력된 send01.action과 매칭되는 action 엘리먼트를 찾은다음

- result 엘리먼트의 목적 주소인 send01.jsp로 이동함.

- send01.jsp에서 회원가입버튼을 눌렀을때 폼의 action 속성의 목적 주소로 이동

- myStruts.xml에서 주소창에 입력된 send01.jsp의 폼 액션 주소인 receive01.action과 매칭되는 action 엘리먼트를 찾은다음

- class 속성의 액션처리용 java 파일(ActionSupport 상속) 내 오버라이딩한 execute() 를 실행한 후 리턴값이 SUCCESS 일 경우

- result 엘리먼트의 목적 주소인 receive01.jsp로 이동함.

- receive01.jsp 실행(EL표현 사용)

struts.properties -> 사용자 주소 입력 -> struts.xml -> myStruts.xml -> send01.jsp -> myStruts.xml -> TestAction.java -> receive01.jsp

//send01.jsp -> 입력 페이지 역할. 입력된 데이터를 서버로 전송.

문제) 여러명의 국어, 영어, 수학 점수를 입력 받아서

총점, 평균, 판정 결과 출력하는 JDBC 프로그램 작성.

오라클, Struts, iBatis 이용.

총점 기준 정렬(내림차순) 출력.

ScoreDTO 작성 추가.

판정 기준은

합격 -> 과목별로 40점 이상이면서, 평균이 60점 이상

과락 -> 과목중에 40점 미만이 있고, 평균은 60점 이상

불합격 -> 평균이 60점 미만

평균이 60점 이상 -> 합격

평균이 60점 미만 -> 불합격

합격 또는 과락 구분은 -> 국어, 영어, 수학 점수가 모두 40점 이상인 확인.

실행 예)

JSTL & EL

1. JSTL(JSP Standard Tag Library), EL(Expreession Language)

2. JSTL은 사용자 정의 태그를 표준화 시킨 것. JSP 내부에서 JSP 명령을 태그 스타일의 명령으로 표현한 것.

3. jstl.jar, standard.jar 파일 필요.

4. JSTL은 core, format, xml, sql 처리 영역이 있다.

- core 영역은 변수 처리, 흐름제어, url 처리등을 담당.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core">

<c:out value="데이터" /> -> 데이터 출력문

<c:set var="변수이름" value="데이터" /> -> 변수 선언문

<c:if test="조건식"> -> if제어문

//실행문

</c:if>

<c:choose> -> if~else제어문

<c:when test="조건식"> </c:when>

<c:otherwise> </c:otherwise>

</c:choose>

<c:forEach var="변수이름" items="컬렉션데이터">

</c:forEach>

5. EL은 표현식(<%=%>)을 대신하는 효과를 가지며 null 값을 가지는 변수에 대해 좀 더 관대하고, 데이터 형 변환을 자동적으로 해준다.

6. EL은 ${표현식} 형태로 표기.

<=%10%>

-> ELK표기법으로 고치면

${dto.id}

회원관리+성적처리 프로젝트

Servlet_20121206.war

1. 성적 테이블, 회원 테이블 조인. FK 설정 필요.

2. 회원(회원번호-PK, 이름, 전화번호) -> 이전과 동일

3. 성적 (성적번호-PK, 회원번호-FK, 국어, 영어, 수학)

-> 이름 대신 회원번호-FK 설정

4. 회원에 회원 등록을 먼저하고, 성적에 성적 입력을 나중에 한다.
