내 서블릿 클래스에서 Spring 컨텍스트를 가져 오는 데 문제가 있습니다. 메서드는 테스트에서 잘 작동합니다 (컨텍스트가로드 된 상태에서). 하지만 난 내 webapp에서 컨텍스트를로드 할 수없는 것 같습니다.web.xml과 Tomcat을 사용하여 Spring 컨텍스트를 올바르게로드하는 방법

이 서버는 단지 상황이 완전히로드 인 경우와 같은 오류가 발생하지 않지만, autowire가 필드는 서블릿에서 널 (null)입니다
서블릿 클래스입니다. 지금까지 나는 시도했다 :
1. 서블릿을 @Service 어노테이션으로 서비스로 등록하고 패키지를 스프링 구성 파일 (test-prova-spring-configuration.xml)의 구성 요소 스캔에 추가한다. > 아무것도 변경되지 않았습니다. 필드는 null이고 Tomcat은 오류를 발생시키지 않았습니다.
2. 스프링 구성 파일에서 bean으로 서블릿을 등록하십시오. -> 아무 것도 변경되지 않았습니다. 필드는 null이고 Tomcat은 오류를 발생시키지 않았습니다.
서블릿에 코드의 그 세 줄을 3.Adding : - :
org.springframework.beans.factory.BeanCreationException : 사출
public void init(javax.servlet.ServletConfig config) throws ServletException {
SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this, config.getServletContext());
};
> 페이지가 (마침내) 오류가 발생 클래스에 대한 autowired 종속성 실패 [class it.jenia.agnese.prova.Presenze];

그러나, 요약, 문제는 서블릿 클래스의 REPO를 autowire하기 위해 콩을 찾을 수 있다는 것입니다.

스택 인쇄의 "정규화 된 Bean 없음"은 일반적으로 Spring Bean 구성의 긴 줄 문제의 마지막 부분입니다. 모든 것을 보여줄 수 있습니까? – BillFromHawaii
