[SOLVED][Kotlin][Spring3] Swagger : Failed to load remote configuration.

 

1. 문제 상황

 

http://localhost:8080/swagger-ui/index.html#/

Failed to load remote configuration.

 

 

 

 

 

2. 문제 원인

 

필자는 Spring Security 적용했을때 위와 같은 상황이 생겼다. Spring Security에서 접근할 수 없도록 막기 때문에 위 현상이 발생했다.

 

 

 

 

 

3. 해결 방법

 

.requestMatchers(AntPathRequestMatcher("/v3/api-docs/**")).permitAll()

permit all로 1개 항목을 더 추가합니다.
