JPM을 사용하여 데이터를 검색하는 tomcat 7 및 mysql 5.1과 함께 Spring 3.2 MVC에서 테스트 사이트를 빌드하려고합니다. 저는 다양한 온라인 의사와 Manning의 "Spring in Action"책을 읽었으며 다양한 접근 방식이나 구성이 가능할 것으로 보입니다.하지만이 유연성 또한 나에게 혼란 스럽습니다.Spring MVC 데이터 소스 문제
나는 다음과 같은 개념이 정확한지 모르겠지만, 아래로 나에게
오류를 수정하는 데 시간이 살려주세요 :

는 조언을 주시기 바랍니다 니펫을 니펫을 니펫을. Spring MVC에 대한 다른 접근법을 말하는 다른 의사를 읽었을 때 위의 내용은 잘못된 방식으로 사용될 수있는 스프링 MVC에 대해 이해하고 있으며 매우 바보 같은 구성 문제 일 수 있습니다. 고맙습니다.
