Question

使用弹簧进行速度配置，我缺少一些配置。请告诉我为什么会这样。点击我的网址时出现以下错误。

SEVERE: Servlet.service() for servlet springDispatcher threw exception

弹簧context.xml中

<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>

我在删除velocityconfig时遇到以下异常。

Answer 1

如果我没错，您将能够仅使用viewResolver来实现速度配置。

将您的前缀修改为resourceLoaderPath中提到的前缀，它应该没问题（我自己没有测试）

<property name="prefix"><value>/WEB-INF/velocity/</value></property>

此外，您可以完全删除velocityConfig标记。

Answer 2

你应该使用

(bean id="ViewResolver" class="org.springframework.web.servlet.view.velocity.VelocityViewResolver")

不是

(bean id="viewResolver" class="org.springframework.web.servlet.view.velocity.VelocityLayoutViewResolver")

这个bean使用＆＃39; layout.vm＆＃39;，我也有这个问题。
