HTTP 상태 500 - 서블릿 appServlet에 대한 Servlet.init()이 예외를 던졌습니다.

Question

간단한 프로그램을 시도하지만 다음 오류가 발생합니다. Eclipse Kelper와 Tomcat 7.0을 사용하고 있습니다. 많은 것을 시도했지만 나에게 도움이되는 것은 없습니다.

Answer 1

이 구성을 사용하거나 이에 따라 구성의 이름을 바꿉니다. 서블릿의 이름을 '디스패처'로 지정하고 컨텍스트 파일을 dispatcher-servlet.xml로 지정하는 것이 좋습니다. 그것은 나를 위해 잘 일했다.

<servlet> 
    <servlet-name>dispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 

    <init-param> 
     <param-name>contextConfigLocation</param-name> 
     <param-value>/WEB-INF/spring/appServlet/dispatcher-servlet.xml</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 

<servlet-mapping> 
    <servlet-name>dispatcher</servlet-name> 
    <url-pattern>/</url-pattern> 
</servlet-mapping>

Servlet.init() 오류는 주로> 인해 항아리 MVC는 프로젝트에 마우스 오른쪽 버튼으로 클릭하여 모든 라이브러리를 확인하여 봄의 파일> 속성 버전의 불일치로 발생 경로를 구축하고, 어떤을 제거 불일치 항아리 릴리스.

또한 lib 폴더에서 jar 라이브러리를 삭제하십시오. 프로젝트를 다시 빌드하고 실행하십시오.

이 밖으로 시도 : 서블릿의 context.xml을 :

    <dep:environment xmlns:dep="http://geronimo.apache.org/xml/ns/deployment-1.1">
