UserDetails

Member Entity 추가

@Entity
@Getter
@NoArgsConstructor
public class Member implements UserDetails {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(unique = true)
    private String email;
    private String name;
    private String password;
    private String address;
    private String role;


    @Builder
    public Member(String email, String name, String password, String address, String role) {
        this.email = email;
        this.name = name;
        this.password = password;
        this.address = address;
        this.role = role;
    }

    @Override
    public Collection<? extends GrantedAuthority> getAuthorities() {
        ArrayList<GrantedAuthority> auth = new ArrayList<>();
        auth.add(new SimpleGrantedAuthority(role);
        return auth;
    }

    @Override
    public String getUsername() {
        return this.email;
    }

    @Override
    public String getPassword(){
        return this.password;
    }

    @Override
    public boolean isAccountNonExpired() {
        return true;
    }

    @Override
    public boolean isAccountNonLocked() {
        return true;
    }

    @Override
    public boolean isCredentialsNonExpired() {
        return true;
    }

    @Override
    public boolean isEnabled() {
        return true;
    }
}

getAuthorities() : 계정이 가지고 있는 권한 목록 리턴
getPassword() : 계정의 비밀번호 리턴
getUsername() : 계정 이름 리턴
다른 블로그를 보면 PK값을 넘겨주는경우가있지만 나는 email을 넘여주었다.

isAccountNonExpired() : 계정이 만료됐는지 리턴 (true 만료 X)
isAccountNonLocked() : 계정이 잠겨있는지 리턴 (true 잠김 X)
isCredentialNonExpired() : 비밀번호가 만료됐는지 리턴 (true 만료 X)
isEnabled() : 계정이 활성화 되있는지 리턴 (true 활성화 O)

UserDetailsService

MemberRepository 수정

public interface MemberRepository extends JpaRepository<Member, Long> {
    Member findByEmail(String email);
}

Email값으로 Member를 찾아주는 findByEmail을 추가하였다.

CustomUserDetailsService 작성

@Service
@RequiredArgsConstructor
public class CustomUserDetailsService implements UserDetailsService {

    private final MemberRepository memberRepository;

    /**
     *
     * @param username the username identifying the user whose data is required.
     * @return Member
     * @throws UsernameNotFoundException
     */
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        Member member = memberRepository.findByEmail(username);

        if(member != null){
            return member;
        }else
            throw new UsernameNotFoundException("can not found User : "+username);
    }
}

loadUserByUsername을 오버라이드해서 작성해야한다.
MemberRepository에서 email값으로 찾아준다음
null인이 체크한뒤 null이면 UsernameNotFoundException
null이 아니면 member를 리턴해준다.
