로그인 기능 중 Authentication 오류

[문민혁]

package practice.semo.Member;

import lombok.RequiredArgsConstructor;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;

@RequiredArgsConstructor
@Controller
public class MemberController {

    private final  MemberRepository memberRepository;
    private final PasswordEncoder passwordEncoder;

    @GetMapping("/register")
    String register(){
        return "register.html";
    }

    @PostMapping("/member")
    String addMember(String username, String password, String displayName){
       DBMember member =  new DBMember();
       var hash = passwordEncoder.encode(password);
       member.setPassword(password);
       member.setUsername(username);
       member.setDisplayName(displayName);
        memberRepository.save(member);
        return "redirect:/list";
    }

    @GetMapping("/login")
    public String login() {
       var result = memberRepository.findByUsername("kim");
        System.out.println(result.get().getDisplayName());
        return "login.html";
    }

    @GetMapping("/mypage")
    public String myPage(Authentication auth) {
        System.out.println(auth);
        System.out.println(auth.getName()); //아이디 확인
        System.out.println(auth.isAuthenticated()); //로그인 여부확인
        return "mypage.html";
    }
}

여기에서 System.out.println(auth.getName()); 과 System.out.println(auth.isAuthenticated()); 부분만 작동이 안됩니다.
혹시 import문제일까요??? 어떻게 해결하나요???

오류 코드입니다

[codingapple]

로그인했는지 확인하거나 SecurityConfig파일이랑 MyUserDetailsService 이상한곳 없나 확인해봅시다
