해결이 되지 않아 다시 문의 드립니다.
console 창 메시지랑 현 상태랑 같이 해서 올립니다 .
감사합니다

저의 경우 아래와 같이 톰캣 실행로그 전 welcomepage가 잡히는데 보이지 않네요.

동일한 코드가 맞다면 자바 버전, 인텔리제이 세팅 등의 문제이지 않나 싶은데요.

자바 버전을 11로 확인해보셔야 할 것 같아요.

build.gradle의 sourceCompatibilitiy도 11로 맞춰주셔야 하구요.

plugins {
   id 'java'
   id 'war'
   id 'org.springframework.boot' version '2.4.3'
   id 'io.spring.dependency-management' version '1.0.11.RELEASE'
}

group = 'hello'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '8'

그전에 index.html을 직접 접근했을 때 어떤지 확인 먼저 해주시면 많은 도움이 될 것 같아요.

http://localhost:8080/index.html

http://localhost:8080/index.html 또한 whitepage로 나타납니다
Java는 11로 변경했습니다만 톰켓 웰컴페이지는 보이지 않네요
setting에서도 11로 변경했습니다.

preferences에서 build and run using 과 Run tests using을 Gradle로 하셨을까요?

IntelliJ라면 Gradle로 변경해서 확인해주세요

넵 다 gradle로 setting 되어있습니다.

위 링크 프로젝트로 확인해보시겠어요?

여전히 그대로 뜹니다
다시 만들어야 할까요??

프로젝트를 다시 만들어서 확인해주세요.

코드는 재사용 해도 됩니다.

넵 알겠습니다~ 다시 해보겠습니다.
