해당 부분은 영한님 강의 자료 5페이지에 설명이 되어 있어서 발췌해왔습니다.
1. 실행을 Gradle로 설정하면, tomcat 의존성을 유지
2. 실행을 IntelliJ IDEA로 설정하면, tomcat 의존성을 제거
저 또한 커뮤니티 에디션으로 테스트를 했다고 말씀 드렸는데, IntelliJ IDEA 실행에 tomcat 의존성을 유지하고도 질문자님과 같은 오류가 발생하지 않았던 이유는, ServletApplication 클래스에 @ServletComponentScan 어노테이션을 붙이지 않고 실행해서 그렇습니다. 즉, 제가 이후 단계인 HelloServlet이 정상 동작하는지까지 테스트하지 않았다는 의미죠.
영한님 강의를 따라가는 전체 흐름으로 보자면 추가로 말씀하신 문제가 충분히 발생할 수 있는데, 제가 거기까지 생각을 못 하고 질문 내용인 메인 메서드 실행에만 중점을 두고 답변을 드린 것 같아 송구합니다.
문제 해결이 잘 되셨으면 좋겠습니다.

친절한 설명 감사드리며
정리하자면 무료버전인경우 @ServletComponentScan 이 있다면 provideRuntime 을 삭제해주면 된다는 거죠 사용은 gradle로 해야하느거구 실행이 지속되는거는 어쩔수 없는거구요
한글깨지는 문제는 utf-8로 해줫는데 왜 깨지는 걸 까요?

1. 정리하자면 무료버전인경우 @ServletComponentScan 이 있다면 provideRuntime 을 삭제해주면 된다는 거죠 사용은 gradle로 해야하느거구 실행이 지속되는거는 어쩔수 없는거구요
→ 커뮤니티 에디션일 때 @ServletComponentScan이 있기 때문에 tomcat 의존성을 삭제하는 것은 아닙니다. 질문 내용을 정리해보자면, 첫 번째 질문처럼 프로젝트 실행 시 메인 메서드가 계속 유지되는 화면 때문에 실행을 IntelliJ IDEA로 변경했는데 이번엔 두 번째 질문처럼 실행이 안 되는 문제가 발생했으니, 추가적인 조치로 tomcat 의존성을 제거하시라고 말씀 드린 겁니다. 커뮤니티 에디션이라서 실행을 꼭 Gradle로 하실 필요는 없으며, IntelliJ IDEA 대신 Gradle로 하고 싶으시다면 실행을 Gradle로 설정하시고 tomcat 의존성을 유지하는 추가적인 옵션도 말씀 드린 거구요.
즉, 에러 발생 여부가 @ServletComponentScan 유무와는 상관이 없습니다. 다만 해당 어노테이션이 없다면 스프링이 서블릿을 자동으로 등록하지 않아 클라이언트 요청을 서블릿이 처리하지 못하겠죠(@ServletComponentScan은 제가 실행을 IntelliJ IDEA로 설정하고 tomcat 의존성을 지우지 않았는데도 두 번째 질문하신 에러가 발생하지 않았던 이유를 설명드리고자 언급한 것이었는데, 괜히 질문자님께서 이해하시는 데 혼란을 드린 거 같아서 죄송합니다). 결론적으로 Gradle을 통한 메인 메서드 실행이 유지되는 화면을 보는 걸 원하지 않으시면 실행은 IntelliJ IDEA, tomcat 의존성은 제거, 두 가지만 설정하시면 됩니다.
2. 한글 깨짐 문제
[��ü �Ķ���� ��ȸ] - end
[���� �Ķ���� ��ȸ]
request.getParameter(username) = hello
request.getParameter(age) = 22
[�̸��� ���� ���� �Ķ���� ��ȸ]
→ 한글을 출력하는 부분이 어디인지 몰라서 파악이 어려운데, 일단 프로젝트 및 파일 인코딩이 UTF-8로 잘 설정되어 있는지 확인해보시면 될 것 같습니다.
프로젝트 인코딩은 [Settings] - [Editor] - [File Encodings] 에서,
파일 인코딩은 파일을 여신 다음 우측 하단에서 확인 가능합니다.

안녕하세요, 사탕님.
IntelliJ에서 프로젝트 실행 시 Gradle을 통해서 실행되도록 설정이 되어 있는 것 같습니다.
해당 내용 관련 설정 방법의 출처는 영한님께서 정리하신 강의 자료 4~5페이지입니다.
아래 이미지대로 설정하시면 될 것 같습니다.
(※ 영한님 혹시 강의 자료 발췌와 관련하여 문제가 된다면 말씀해주시기 바랍니다.)
조금이나마 도움이 되었으면 좋겠습니다.
