실핼 시 오류 발생 -1 발생

이유 : ssar이 DB에 존재 X

동작 순서 확인

successfulAuthentication 발동

강제로그인 발동 -> UserDetailsService를 구현한 LoginService 발동

이때 Username을 넣는데, username이 없기 때문에 InternalAuthenticationServiceException 에러 발생

에러를 catach 해서

아래의 unsuccessfulAuthentication 발동

잡지식, test.yml

SQL 문을 이쁘게 format 해줌

• test.yml TRACE 확인을 위한 테스트 코드 추가

@ActiveProfiles("test") // 여기
@AutoConfigureMockMvc
@SpringBootTest(webEnvironment = WebEnvironment.MOCK)
public class JwtAuthenticationFilterTest extends DummyObject {

TRACE가 있으면 어떤 값들이 들어왔는지 알 수 있다. 따라서 TEST 할때는 TRACE를 추가하자.

이렇게 결과가 나왔다는 것은,

여기서 토큰이 만들어지고

위에 사진에서 실행이 됬다는 것은 UserDetailsService가 실행이 잘 되어서 LoginUser를 리턴하고 Authentication이 잘 만들어진 것이다.

디버그를 해보면 잘 나왔을 것이다.

• 최종 코드

          String reqeustBody = om.writeValueAsString(loginRequestDto);
          System.out.println("테스트 : " + reqeustBody);

          // when
          ResultActions resultActions = mvc
                    .perform(post("/api/login").content(reqeustBody).contentType(MediaType.APPLICATION_JSON));
          String reasponseBody = resultActions.andReturn().getResponse().getContentAsString();
          String jwtToken = resultActions.andReturn().getResponse().getHeader(JwtValueObject.HEADER);
          System.out.println("테스트 : " + reasponseBody);
          System.out.println("테스트 : " + jwtToken);

          // then

          assertNotNull(jwtToken);
