[20210714] Spring + MyBatis를 이용한 게시판 4 - spring-app.xml, spring-controller.xml

spring-app.xml: 스프링 웹 프로젝트의 mvc 구조에 대한 설명을 담고 있다. 애너테이션(annotation)을 사용하기 위해 <mvc:annotation-driven /> 태그를 사용하고, 기본 서블릿 핸들러를 핸들러 매핑으로 사용하며, 뷰 결정자(view resolvers)는 컨트롤러가 반환한 값 앞에 '/views/'를 붙이고 뒤에는 '.jsp'를 붙인 뷰를 사용할 것이라고 설정하였다.

spring-controller.xml: 스프링 웹 개발을 위한 빈 객체들을 담고 있다. DAO, SQLSessionFactorybean, Property, DataSource, SqlSessionTemplate을 스프링 컨테이너(또는 IoC 컨테이너)에 담는다.
