🚨 Error: JWT 생성 에러 (java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter)

[jaynamm]

로그인에 성공하게 되면 JWT 토큰을 생성하게 되는데 토큰 생성할 때 다음과 같이 에러가 발생했다.

로그인 구현 부분

    @PostMapping("login")
    public String loginCheck(@RequestBody Map<String, String > loginMember) {
        // 로그인한 사용자의 userid 를 가져와서 사용자 정보를 가져옴
        UserDetails member = memberSecurityService.loadUserByUsername(loginMember.get("userid"));

        if(!passwordEncoder.matches(loginMember.get("password"), member.getPassword())) {
            throw new IllegalArgumentException("잘못된 비밀번호입니다.");
        }

        String userid = member.getUsername();
        String roles = member.getAuthorities().stream().toList().get(0).toString();

        return jwtTokenProvider.generateToken(userid, roles);
    }

JWT 토큰 생성 부분

    public static String generateToken(String userid, String roles) {
        Date now = new Date();
        Date expiredDate = new Date(now.getTime() + JWT_EXPIRATION_MS);

        // 사용자 정보 설정
        Claims claims = Jwts.claims().setSubject(userid);
        claims.put("roles", roles); // 정보는 key:value 형태로 저장된다.

        return Jwts.builder()
                // .setSubject(userid) // 토큰 제목 -> Claim 으로 대체
                .setClaims(claims) // 사용자 정보 저장
                .setIssuedAt(now) // 토큰 생성 시간
                .setExpiration(expiredDate) // 토큰 만료시간 - 생성 시간으으로부터 30분으로 설정
                .signWith(SignatureAlgorithm.HS256, JWT_SECRET) // 암호화 알고리즘 설정
                .compact(); // 생성 완료
    }

스프링 시큐리티 설정 부분

@Bean
    SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.httpBasic().disable() // REST API 를 사용하기 위해 http 기본 설정 해제
                .csrf().disable() // REST API 를 사용하기 위해 csrf 보안 비활성화
                .headers()
                .and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS) // JWT 토큰 기반 인증이므로 세션을 사용하지 않는다.
                //.csrf().ignoringRequestMatchers(new AntPathRequestMatcher("/h2-console/**"))
                //.and()
                //.addHeaderWriter(new XFrameOptionsHeaderWriter(XFrameOptionsHeaderWriter.XFrameOptionsMode.SAMEORIGIN))
                .and()
                .authorizeHttpRequests().requestMatchers(
                        new AntPathRequestMatcher("/**")).permitAll()

                // 로그인 구현
                .and()
                .formLogin()
                .loginPage("/member/login") // 로그인 페이지
                .defaultSuccessUrl("/home") // 로그인 성공
                .usernameParameter("userid") // loadUserByUsername 의 username 파라미터값 변경

                // 로그아웃 구현
                .and()
                .logout()
                .logoutRequestMatcher(new AntPathRequestMatcher("/member/logout"))
                .logoutSuccessUrl("/")
                .invalidateHttpSession(true)
        ;

        return http.build();
    }

로그인 POST API 결과 확인

{
    "timestamp": "2023-04-22T16:50:44.314+00:00",
    "status": 500,
    "error": "Internal Server Error",
    "path": "/api/member/login"
}

JWT 토큰을 사용하기 위해서는 다음과 같이 추가적으로 Dependency 를 추가해주어야 한다고 한다.

build.gradle Dependency 추가

// com.sun.xml.bind
    implementation 'com.sun.xml.bind:jaxb-impl:4.0.1'
    implementation 'com.sun.xml.bind:jaxb-core:4.0.1'
    // javax.xml.bind
    implementation 'javax.xml.bind:jaxb-api:2.4.0-b180830.0359'

Dependency 추가 후 다시 빌드 그리고 API 실행 결과

eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhYWEiLCJyb2xlcyI6IlJPTEVfVVNFUiIsImlhdCI6MTY4MjE4MjgxNiwiZXhwIjoxNjgyMTg0NjE2fQ.Q8N-PL7FJyOxXgLqfB0ewIjZ7bxboLRiT-h-XKn8894

정상적으로 토큰값을 생성하는 것을 확인할 수 있었다.

토큰 내용은 아래와 같다.
