spring boot에서 swagger를 설정하고 난 뒤, 실행을 하니

아래와 같은 에러가 떳다.

 

org.springframework.context.ApplicationContextException: Failed to start bean 'documentationPluginsBootstrapper'; nested exception is java.lang.NullPointerException

 

그래서 application.propertis에

설정값을 추가 해줬고 다시 실행하니 정상적으로  swagger가 실행이 되었다.
