本文介绍如何在Spring环境中配置Velocity模板引擎，并演示了一个简单的测试案例，包括设置资源加载路径及编码格式等。

applicatioin-context.xml

	<bean id="velocityEngine" class="org.springframework.ui.velocity.VelocityEngineFactoryBean">
		<property name="velocityProperties">
			<props>
				<prop key="resource.loader">file</prop>
				<prop key="file.resource.loader.path">.</prop>
				<prop key="file.resource.loader.class">
					org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader
				</prop>
				<prop key="input.encoding">UTF-8</prop>
				<prop key="output.encoding">UTF-8</prop>
			</props>
		</property>
	</bean>

invite_email.vm

<br>$name
<br>$content
<br><img src="$img"/>

Test

	@Test
	public void testMergeTemplateIntoString() {
		Map<String, String> map = new HashMap<String, String>();
		map.put("name", "张三");
		map.put("content", "This is content!!!");
		map.put("img", "http://www.iknowing.com/photos/1/1/1.jpg");
		
		String vm = "invite_email.vm";
		
		String html = templateService.mergeTemplateIntoString(vm, map);
		System.out.println(html);
	}

TemplateService

private static String tplFolder = "templates/";
	
	@Autowired
	private VelocityEngine velocityEngine;
	
	@Override
	public String mergeTemplateIntoString(String vm, Map<String, String> map) {
		String tpl = tplFolder + vm;
		return VelocityEngineUtils.mergeTemplateIntoString(velocityEngine, tpl, map);
	}
