web.xml 파일의 내용입니다입니다 . 아무도 내가 문제를 해결하는 데 도움이 될 수 없습니다.

Answer 1

나는 또한 동일한 문제에 직면했다. 그러나 나는 해결책을 얻었다.
Tomcat 서버를 사용하는 경우 tomcat의 jar 파일을 WEB-INF/lib에 넣으면 안됩니다. Tomcat에는 이미 클래스가 있으며, 웹 애플리케이션 클래스 로더가 아닌 루트 tomcat 클래스 로더에 의해로드되어야합니다.
WEB-INF/lib 폴더를 확인하고 모든 tomcat의 jar를 삭제하십시오 (예 : tomcat-api-8.0.0-RC1.jar, tomcat-juli-8.0.0-RC1.jar, tomcat-util-8.0). .0-RC1.jar, tomcat-servlet-api-8.0.0-RC1.jar). 대신 web.xml 파일에 구성

Answer 2

는 Shrikant의 게시물을 참조에서 SpringBootServletInitializer를 구현하는 클래스,

Answer 3

를 사용 - 종류의.

Tomcat을 사용할 때 Tomcat의 jar 파일을 WEB-INF/lib 폴더에 포함시키지 않으실 것입니다.

jar는 스프링 부트에 대한 Maven 종속성에서 비롯된 것입니다. 내가 확장 된 치어의 종속성 계층 구조 보았고 바람둥이 단지는 어디로부터 볼 때까지 스프링 부팅 항아리가 너무

<dependency> 
     <groupId>org.springframework.boot</groupId> 
     <artifactId>spring-boot-starter-web</artifactId> 
     <scope>provided</scope> 
    </dependency> 

처럼, 당신의 치어에 제공하도록 지정 이 나에게 악화의 비트를 일으켰습니다. 스프링 부트 의존성에서 컴파일 대신 제공된 범위를 변경하면 내 페이지가 잘로드됩니다.

Shrikant -> 당신의 대답에 대한 진실은 아무것도 아닙니다. lib 디렉토리에서 jar 파일을 지우고 전쟁을 만들 때 신경 쓰지 않아도됩니다. 한 번에 모든 것을 정리하고, 패키지하고, 설치하고 배포 할 수 있습니다. 하나의 버튼.
