Spring /WEB-INF子文件夹中的Velocity电子邮件模板

我编码了发送电子邮件的服务。现在我必须集成velocity-freamwork，所以我编辑了我的mail-context.xml

....
<bean id="mailService" class="xxx.xxxx.xxxx.service.MailServiceImpl">
        <property name="mailSender" ref="mailSender" />
        <property name="simpleMailMessage" ref="customeMailMessage" />
        <property name="velocityEngine" ref="velocityEngine" />
    </bean>

    <bean id="velocityEngine"
        class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
        <property name="velocityProperties">
            <props>
                <prop key="resource.loader">webapp</prop>
                <prop key="webapp.resource.loader.class">org.apache.velocity.tools.view.WebappResourceLoader</prop>
                <prop key="webapp.resource.loader.path">/WEB-INF/email</prop>
            </props>
        </property>
    </bean>
...

然后，堆栈跟踪被删除

有什么建议吗？

将

velocityEngine

bean更改为

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="resourceLoaderPath" value="/WEB-INF/email/" />
</bean>

它应该可以工作。

你确定模板

/WEB-INF/email/test.vm

存在吗？当然！我写了这篇文章并把它放到/WEB-INF/email文件夹中。你的资源路径可能会被关闭。您是否配置了其他资源加载程序？我写了一个测试，它按预期工作。唯一的区别是测试使用类路径。这解释了一切：-）出于测试目的，只需将模板存储在类路径上。或者，如果您正在使用maven，请将其放入

test/resources

。

<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
    <property name="resourceLoaderPath" value="/WEB-INF/email/" />
</bean>
