webx3中如何添加自定义velocity块指令？

[iamchenney]

我添加了

<beans:bean id="velocityConfigurer" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
        <!--<beans:property name="resourceLoaderPath" value="/velocity 模板目录/"/>-->
        <beans:property name= "velocityProperties">
            <beans:props>
                <beans:prop key="input.encoding">utf-8</beans:prop>
                <beans:prop key="output.encoding">utf-8</beans:prop>
                <beans:prop key="userdirective">com.my.directive.Script</beans:prop>
            </beans:props>
        </beans:property>
    </beans:bean>

但是vm依然解析不了#script()
