[서블릿 설정 xml ] spring 3.x 이상, jackson 2.x이상 은 MappingJackson2JsonView, 그외에는 MappingJacksonJsonView 클래스 명을 사용한다.

<!-- ajax를 처리할 resolver의 load 순서를 0으로 하여 먼저 인식하도록 함  -->

	<bean id="jsonView" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">

<bean class="org.springframework.web.servlet.view.BeanNameViewResolver">

		<property name="order" value="1">

<!-- 여러가지를 먼저 처리할 resolver가 있는 경우 스프링 기본제공 resolver는 최하위 순서가 되는 경우가 많다. 그냥 맨 뒤로 빼자 -->

	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <!-- Example: a logical view name of 'showMessage' is mapped to '/WEB-INF/jsp/showMessage.jsp' -->
