■ 데이터베이스 생성
create table tblCode (
seq number primary key, --번호(PK)
subject varchar2(500) not null, --제목(설명)
code varchar2(2000) not null, --코드조각
regdate date default sysdate not null,
language varchar2(50) not null --언어 종류
);
create sequence seqCode;
■ 파일 생성

> CodeDAOImpl.java(C)
"com.test.domain" > CodeDTO.java
views > "list.jsp"

★ 기능 별 Coading
■ 추가 기능
------------------------------- CodeController.java
@PostMapping("/addok.do")
public String addok(CodeDTO dto) {
int result = dao.add(dto);
if(result == 1) {
return "redirect:/list.do";
} else {
return "redirect:/add.do";
}
}
------------------------------- CodeDAO.java
int add(CodeDTO dto);
------------------------------- CodeDAOImpl.java
@Override
public int add(CodeDTO dto) {
return template.insert("code.add", dto);
}
------------------------------- code.xml
<insert id="add">
insert into tblCode (seq, subject, code, regdate, language)
values (seqCode.nextVal, #{subject}, #{code}, default, #{language})
</insert>
■ 리스트 목록 띄우기 기능
------------------------------- CodeController.java
@GetMapping("/list.do")
public String list(Model model) {
List<CodeDTO> list = dao.list();
model.addAttribute("list", list);
return "list";
}
------------------------------- CodeDAO.java
List<CodeDTO> list();
------------------------------- CodeDAOImpl.java
@Override
public List<CodeDTO> list() {
return template.selectList("code.list");
}
------------------------------- code.xml
<select id="list" resultType="com.test.domain.CodeDTO">
select
seq, subject, regdate, language
from tblCode
order by seq desc
</select>
■ 상세 보기 기능
------------------------------- CodeController.java
@GetMapping("/view.do")
public String view(Model model, String seq) {
CodeDTO dto = dao.view(seq);
model.addAttribute("dto", dto);
return "view";
}
------------------------------- CodeDAO.java
CodeDTO view(String seq);
------------------------------- CodeDAOImpl.java
@Override
public CodeDTO view(String seq) {
return template.selectOne("code.view", seq);
}
------------------------------- code.xml
<select id="view" resultType="com.test.domain.CodeDTO">
