🌈 웹 MVC
회원 웹 기능 - 홈 화면 추가
// 홈 컨트롤러
@Controller
public class HomeController {
@GetMapping("/")
public String home(){
return "home";
}
}// 회원 관리용 홈
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<body>
<div class="container">
<div>
<h1>Hello Spring</h1>
<p>회원 기능</p>
<p>
<a href="/members/new">회원 가입</a>
<a href="/members">회원 목록</a>
</p>
</div>
</div> <!-- /container -->
</body>

- 컨트롤러가 정적 파일보다 우선순위가 높아 컨트롤러를 먼저 사용한다.
회원 웹 기능 - 등록
// 회원 등록 폼 컨트롤러
@Controller
public class MemberController {
private final MemberService memberService;
@Autowired // 빈 등록
public MemberController(MemberService memberService) {
this.memberService = memberService;
}
@GetMapping(value = "/members/new")
public String createForm() {
return "members/createMemberForm";
}
/* 회원을 실제 등록하는 기능 */
@PostMapping(value = "/members/new")
public String create(MemberForm form) {
Member member = new Member();
member.setName(form.getName());
memberService.join(member);
return "redirect:/";
}
}// 회원 등록 폼 HTML
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
