내 웹 응용 프로그램을 호스팅하는 내 서버와 내 Android 앱을 통신하려고합니다. 웹 측면에서 봄을 사용하고 있으며 모든 것이 잘 작동하고있었습니다. 나는 봄 등을 사용하여 데이터베이스 용 데이터를 보낼 수 있습니다.하지만 이제는 안드로이드 앱이 서버와 통신하도록 노력하고 있습니다. 이를 위해 본 튜토리얼을 따라 갔다 : http://blog.trifork.com/2011/02/07/creating-an-android-app-for-your-website-with-spring-android-and-rest/ContentNegotiatingViewResolver를 만드는 동안 BeanCreationException이 발생했습니다.
이제 웹 페이지를 열려고 할 때 많은 예외가 발생한다. (나는 안드로이드 애플 리케이션에서 아무것도 보내려고하지 않아도!). 내 springmvc-servlet.xml에 코드를 작성하기 전까지는 정상적으로 작동했습니다.
스프링에 익숙하지 않으므로이 예외를 해결하는 동안 문제가 발생합니다. 여기 내 sprinmvc-servlet.xml 파일의 코드이다 (I 다른 사람 자습서 다음 코드의 일부를 변경,하지만 난 내가 사용하는 첫 번째 튜토리얼의 코드를 사용할 때, 나는 같은 예외를 얻을)
