원인

AbstractView를 상속받은 View 파일을 생성하고, BeanNameViewResolver 선언하지 않았기 때문에 발생하는 문제입니다.

BeanNameViewResolver  와 UrlBasedViewResolver 중 BeanNameViewResolver 를 우선순위 높게 먼저 선언해야 합니다.

---

    <!-- beanNameResolver는 우선순위를 0으로 해서 ViewPage를 찾을 때 우선 탐색한다. 
    만약 BeanNameViewResolver에서 없으면 UrlBasedViewResolve에서 탐색한다. -->
    <bean id="beanNameResolver" class="org.springframework.web.servlet.view.BeanNameViewResolver">
        <property name="order" value="0"/>
    </bean>

    <bean id="viewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" />
        <property name="order" value="1" /> <!-- 순서를 지정하는 property -->
    </bean>

    <bean id="fileDownload" class="simple.spring.view.FileDownloadView" />
