Spring Boot 2.6.x 버전에 springfox-boot-starter
(Swagger 3.0) 종속성이 도입된 후 컨테이너를 시작할 때 오류가 보고됩니다. springfox-boot-starter
(Swagger 3.0) 后,启动容器会报错:
Failed to start bean ‘ documentationPluginsBootstrapper ‘ ; nested exception…
Springfox 假设 Spring MVC 的路径匹配策略是 ant-path-matcher
,而 Spring Boot 2.6.x版本的默认匹配策略是 path-pattern-matcher
bean 시작 실패 ‘ documentPluginsBootstrapper ‘ 중첩된 예외... 기본 일치 전략은path-pattern-matcher
이며, 이로 인해 위 오류가 발생합니다. 완전한 솔루션:1. pom 구성2.
