我有一个Spring web应用程序，我需要运行json服务。
下面是我程序的调度程序 - servlet。

<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
<bean name="viewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
<property name="location">
<value>/WEB-INF/views.xml</value>
</property>
<property name="order">
<value>1</value>
</property>
</bean>
</beans>
这是views.xml代码。
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd">
<bean name="jsonView" class="org.springframework.web.servlet.view.json.JsonView"/>
</beans>
我在控制台中收到以下错误，我在问题标题中说明了这一点。
