각 영역의 네이밍 규칙

xxController
스프링 MVC에서 동작하는 Controller 클래스
xxService, xxServiceImpl
비즈니스 영역을 담당하는 인터페이스는 ~~Service라는 방식을 사용하고,
인터페이스를 구현한 클래스는 ~~ServiceImpl이라는 이름을 사용
xxDAO, xxRepository
DAO(Data-Access-Object)나 Repository(저장소)라는 이름으로 영역을 따로 구성하는 것이 보편적
VO, DTO
VO의 경우 주로 ReadOnly의 목적이 강하고 데이터 자체도 불변하게 설계
DTO는 주로 데이터 수집의 용도로 사용

패키지 네이밍 규칙(ex. com.001cloudid)

.config : 프로젝트와 관련된 설정 클래스들의 보관 패키지
.controller : 스프링 MVC의 Controller들의 보관 패키지
.service : 스프링 Service 인터페이스와 구현 클래스 패키지
.domain : VO, DTO 클래스들의 패키지
.persistence : MyBatis Mapper 인터페이스 패키지
.exception : 웹 관련 예외처리 패키지
.aop : 스프링의 AOP 관련 패키지
.security : 스프링 Security 관련 패키지
.util : 각종 유틸리티 클래스 관련 패키지

와이어 프레임(기본적인 게시물의 CRUD 흐름) ※구현의 시작부

/board/list(게시물 목록) → /board/register(게시물 등록) → /board/list(게시물 목록 결과)

/board/list(게시물 목록) → /board/get(게시물 조회) → /board/modify(게시물 수정/삭제) → /board/list(게시물 목록 결과)

프로젝트의 생성 및 준비

Spring Legacy Project 생성
pom.xml에서 스프링 버전 변경
spring-test, spring-jdbc, spring-tx 추가
junit 버전 번경
Servlet 버전 변경
HikariCP, MyBatis, mybatis-spring, Log4jdbc 추가
JDBC 드라이버 프로젝트 내 추가
기타 Lombok의 설정

1. Spring Legacy Project 생성

Spring MVC Project

2. pom.xml 수정

스프링 버전, 자바 버전 수정

spring-tx, spring-jdbc, spring-test 추가

MyBatis를 이용할 예정임므로 HikariCP, MyBatis, mybatis-spring, Log4jdbc 라이브러리 추가

테스트를 위한 jUnit 버전 변경 및 Lombok 추가

Servlet 3.0이상을 제대로 사용하기 위해서 서브릿 2.5버전이 아닌 3.0이상으로 수정

데이터베이스 내 테이블 생성

create SEQUENCE seq_board; -- 아무 의미가 없는 번호/구분을 위한 번호

create table tbl_board(
    bno number(10,0),
    title varchar2(200) not null,
    content varchar2(2000) not null,
    writer varchar2(50) not null,
    regdate date default sysdate,
    updatedate date default sysdate
);

-- 모든 데이터베이스에 저장되는 것은 명사와 히스토리


-- PK
alter table tbl_board add constraint pk_board
primary  key(bno);

더미 데이터의 추가 → 추가시 한글이 깨지는지 확인 → 데이터 추가 시 한글로 된 데이터로

insert into tbl_board(bno, title, content, writer)
values(seq_board.nextval, '테스트 제목', '테스트 내용', 'user00');

※ 자바 파일은 실행하기전 반드시 저장하듯이 dbms는 커밋을 해줘야함

영속 계층 구현

테이블의 컬럼 구조를 반영하는 VO(Value Object) 클래스의 생성
MyBatis의 Mapper 인터페이스의 작성/XML 처리
작성한 Mapper 인터페이스의 테스트

VO클래스 → 테이블과 동일하게 맞춰주면 됨

BoardVO

package org.zerock.domain;

import java.util.Date;

import lombok.Data;

@Data
public class BoardVO {
	
	// 데이터베이스 관련 작업을 할 때는 소문자로 하지 않음 → 소문자로 하면 기본값을 가짐
	
	private Long bno;
	private String title, content, writer;
	private Date regdate, updateDate;
	
}

Mapper 인터페이스 작성

BoardMapper

package org.zerock.mapper;

import java.util.List;

import org.zerock.domain.BoardVO;

public interface BoardMapper {

	List<BoardVO> getList();
	
}

BoardMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
	PUBLIC "-//mybatis.org/DTD Mapper 3.0//EN"
	"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="org.zerock.mapper.BoardMapper">

	<select id="getList" resultType="org.zerock.domain.BoardVO">
		select * from tbl_board order by bno desc
	</select>
