[로그인] 회원가입

1. Member

---

package hello.login.domain.member;

import lombok.Data;
import javax.validation.constraints.NotEmpty;

@Data
public class Member {

    private Long id;

    @NotEmpty
    private String loginId; //로그인id
    @NotEmpty
    private String name;
    @NotEmpty
    private String password;

}

 

 

2. MemberRepository

---

• loginId로 찾는 메서드 추가

package hello.login.domain.member;

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Repository;

import java.util.*;

@Slf4j
@Repository
public class MemberRepository {

    private static Map<Long, Member> store = new HashMap<>();

    private static long sequence = 0L;

    public Member save(Member member){
        member.setId(++sequence);
        log.info("save : member = {}", member);
        store.put(member.getId(), member);
        return member;
    }

    public Member findById(Long ig){
        return store.get(ig);
    }

    public List<Member> findAll(){
        return new ArrayList<>(store.values());
    }

    public Optional<Member> findByLoginId(String loginId){

        return findAll().stream().
                filter(m -> m.getLoginId().equals(loginId)).findFirst();
    }

    public void clearStore(){
        store.clear();
    }
}

 

 

 

3. MemberController

---

• Bean Validation을 위해 @Validated 추가,
• Validation 결과 보관을 위해 BindingResult 추가.

package hello.login.web.member;

import hello.login.domain.member.Member;
import hello.login.domain.member.MemberRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Controller;
import org.springframework.validation.BindingResult;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequiredArgsConstructor
@RequestMapping("/members")
public class MemberController {

    private final MemberRepository memberRepository;

    @GetMapping("/add")
    public String addForm(@ModelAttribute("member") Member member){
        return "members/addMemberForm";

    }

    @PostMapping("/add")
    public String save(@Validated @ModelAttribute("member") Member member, BindingResult bindingResult){
        if(bindingResult.hasErrors()){
            return "members/addMemberForm";
        }

        memberRepository.save(member);
        return "redirect:/";
    }
}

 

 

4. 테스트용 데이터

package hello.login;

import hello.login.domain.item.Item;
import hello.login.domain.item.ItemRepository;
import hello.login.domain.member.Member;
import hello.login.domain.member.MemberRepository;
import lombok.RequiredArgsConstructor;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component
@RequiredArgsConstructor
public class TestDataInit {

    private final ItemRepository itemRepository;
    private final MemberRepository memberRepository;

    /**
     * 테스트용 데이터 추가
     */
    @PostConstruct
    public void init() {
        itemRepository.save(new Item("itemA", 10000, 10));
        itemRepository.save(new Item("itemB", 20000, 20));

        Member member = new Member();
        member.setLoginId("test");
        member.setPassword("test!");
        member.setName("테스터");
        memberRepository.save(member);

    }

}
