시도 방법:
1. Tomcat의 서버를 수정합니다.xml 프로필
왜냐하면 Tomcat의 서버입니다.xml 프로필이 마지막으로 많이 나온 이 몇 줄은 이전에 Eclipse에서 뛰었던 프로젝트가 자동으로 생성된 것으로 추정된다.그것들을 삭제한 후에 Tomcat은 정상적으로 운행되었다.
 
2. JDK 버전 수정
3. 포트 번호 조회, 점용되지 않음
실제 해결 방법:
발생 원인:tomcat에도 servlet-api 패키지가 있습니다. 이렇게 충돌이 발생했습니다.
해결 방법:provided를 추가합니다. provided는 이 패키지를 컴파일하고 테스트할 때만 사용한다는 것을 표시하기 때문에tomcat을 시작할 때 충돌하지 않습니다. 온전한 의존은 다음과 같습니다.
자바 ee jar 패키지를 가져올 때 추가:provided

		
			javax.servlet
			jsp-api
			2.0
			provided
		
		
			javax.servlet
			javax.servlet-api
			3.1.0
			provided
