}/favicon.ico 요청을 직접 처리하게 설정한다.
왜 필요한가?
Spring Boot는 기본적으로 /favicon.ico 요청을 정적 리소스에서 찾지만,
- 일부 설정에서는 404가 발생할 수 있고
- WebMvcConfigurer를 커스터마이징한 경우 정적 핸들링이 깨질 수 있다.
그래서 이처럼 직접 핸들러 매핑을 설정해서 명시적으로 /favicon.ico 요청을 처리하게 할 수 있다.
WebConfig
// favicon.ico 요청을 처리하는 리소스 핸들러 추가
registry.addResourceHandler("/favicon.ico")
.addResourceLocations("classpath:/static/");
// 정적 리소스 처리 추가
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/static/");
