Spring MVC ContentNegotiatingViewResolver 样例 根据不同的url地址后缀返回不同类型的数据

spring-controller.xml 中配置 ContentNegotiatingViewResolver

<!-- 根据客户端不同的请求进行不同的相应，如/blog/1.do ,/blog/1.xml -->
	<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
		<!-- 设置为true以忽略对Accept Header的支持 -->
		<property name="ignoreAcceptHeader" value="true" />
		<!-- 在没有扩展名时即: "/blog/1" 时的默认展现形式 -->
		<property name="defaultContentType" value="application/json" />
		<!-- 扩展名至mimeType的映射,即 /blog.json => application/json -->
		<property name="mediaTypes">
			<map>
				<entry key="html" value="text/html" />
				<entry key="xml" value="application/xml" />
				<entry key="json" value="application/json" />
			</map>
		</property>
		<!-- 用于开启 /blog/123?format=json 的支持 -->
		<property name="favorParameter" value="false" />
		<property name="favorPathExtension" value="true"></property>
		<property name="viewResolvers">
			<list>
