혹시 시큐리티 컨피규레이션 쓰면 "/v2/api-docs", "/configuration/**", "/swagger*/**", "/webjars/**" 요것들 권한 permitAll로 바꾼다.
 .antMatchers("/resources/**","/css/**", "/images/**","/configuration/**", "/js/**", "/h2-console/**","/v2/api-docs", "/configuration/**", "/swagger*/**", "/webjars/**")
 .permitAll()

만약 이거 해도 안되면 인텔리제이,sts,비쥬얼스튜디오 세개다 써서 켜봣는데

인텔리제이랑 sts는 되는데 비쥬얼스튜디오로 키면 swagger.html 안된다.

v2/api-docs 는 세개다됨 우선 저거 되는지보고 되면 툴을 다른거로 바꿔서 서버실행해보세요!
