문제점을 찾을 수 없습니다.Spring에서 제출 한 후 Servlet이 POST 메소드에 액세스하지 않습니다.
일반적으로 IDE가 기본값으로 설정 한 모든 것을 사용 하겠지만, 요구 사항에 따라 스프링 MVC를 사용하면 표준을 충족하기 위해 applicationContext.xml 및 dispatcher-servlet.xml 만 삭제해야합니다. 내가 그것을했을 때, web.xml 파일 때문에 Servlet의 GET 메소드를 얻을 수 있었기 때문에 작동을 멈추었지만, POST 메소드를 사용할 때 "요청한 리소스를 사용할 수 없습니다."라는 메시지가 나옵니다. 오류.
이 오류를 표시하지 않고 POST 방법을 사용하려면 어떻게해야합니까?

RecibirDatos 클래스의 doPost()가 호출되는지 여부를 확인하고 알려주십시오. – Mudassar
또한 전화를 걸기 위해 프로젝트를 어떻게 구조화했는지 조금 궁금합니다. – Mudassar
