Spring( urlMapping 이용)

결과적으로 ViewName으로부터 EL문을 사용한 jsp파일에 연결된다. 이 때 꼭 필요한 것이
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>spring.xml 파일에 viewResolver 라는 이름으로 prefix와 suffix를 이용해 고정된 파일 경로와 포맷을 지정해주는 것이다.

web.xml과 spring.xml
web.xml 에는 *.pknu 를 통해 spring.xml 에서 정보를 얻어 접속하는 것을 init-param으로 작성하고 spring.xml 에는 dbcp 접속정보 , dbcp import, 보여질 코드를 작성할 CtrlSpring 에 대한 Bean 연결 내용이 작성된다.
