Velocity, Can't find resource

Velocity 邮件模板在Spring 中发邮件报unable to find resource 'WEB-INF/test.vm' in any resource loader导常。配置如下：

    <bean id="templateMail" class="com.chenlb.mail.VelocityTemplateMessage">
        <property name="javaMailSender" ref="mailSender"></property>
        <property name="from" value="${mail.from}"></property>
        <property name="encoding" value="UTF-8"></property>
        <property name="templateLocation" value="WEB-INF/test.vm"></property>
        <property name="velocityEngine">
            <bean class="org.springframework.ui.velocity.VelocityEngineFactoryBean"></bean>
        </property>
        <property name="title" value="www.blogjava.net/chenlb"></property>
    </bean>

邮件内容生成如下：
VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, templateLocation, encoding, model);

但导常，说不可用的资源。

说明：VelocityEngineUtils.mergeTemplateIntoString()里的templateLocation的文件，不会像Spring一样找。然后就看Spring 的 VelocityEnginFactory API和试，最后发现<bean class="org.springframework.ui.velocity.VelocityEngineFactoryBean"></bean>
单独定义，并配置resourceLoaderPath属性即可搞定。

配置后的：
    <bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
        <property name="resourceLoaderPath" value="WEB-INF/"></property>
    </bean>
   
    <bean id="templateMail" class="com.chenlb.mail.VelocityTemplateMessage">
        <property name="javaMailSender" ref="mailSender"></property>
        <property name="from" value="${mail.from}"></property>
        <property name="encoding" value="UTF-8"></property>
        <property name="templateLocation" value="test.vm"></property>
        <property name="velocityEngine" ref="velocityEngine"></property>
        <property name="title" value="wwww.blogjava.net/chenlb"></property>
    </bean>

resourceLoaderPath是由Spring设置过的，跟平常的(Spring)文件资源一样方式引用，Spring真的太方便了。
