带弹簧的速度配置，我缺少一些配置。请告诉我为什么会这样。当我点击我的网址时出现以下错误。

弹簧上下文.xml
<bean id="velocityConfig"
class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<property name="resourceLoaderPath" value="/WEB-INF/velocity/" />
</bean>
<!-- View resolvers can also be configured with ResourceBundles or XML files.
If you need different view resolving based on Locale, you have to use the
resource bundle resolver. -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="" />
<property name="suffix" value=".vm" />
</bean>
当velocityconfig被删除时，我得到了以下异常。
