spring集成freemaker 制作短信模板

1、配置configure的Bean，Bean中指定了模板文件的路径和刷新时间等配置。

    <!-- 配置freeMarkerConfigurer进行属性值的注入 -->
    <bean id="freeMarkerConfigurer"
        class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
        <property name="templateLoaderPaths"
            value="classpath:SMSTemplate" />
        <property name="freemarkerSettings">
            <props>
                <prop key="template_update_delay">1800</prop><!-- 模板更新延时 -->
                <prop key="default_encoding">UTF-8</prop>
                <prop key="locale">zh_CN</prop>
            </props>
        </property>  

    </bean>

2、定义模板文件。

<#compress>
实时气象信息：风向为在${weatherInfo.windDir!}，<#rt>
${weatherInfo.windPower!}。<#rt>
今日${weatherInfo.stateDetailed!}，<#rt>
最高温度${weatherInfo.tem1!}<#rt>
。<#rt>
</#compress>

3、模板+数据=实际需要的内容

@Component
public class FreeMarkService {

	private Log logger = LogFactory.getLog(FreeMarkService.class);
	@Autowired
	private FreeMarkerConfigurer freeMarkerConfigurer;

	/**
	 * 传入weatherInfo得到天气短信的模板
	 * @param weatherInfo
	 * @return
	 */
	public String generateSmsByWeatherInfo(WeatherInfo weatherInfo) {

		String retSmsContent = "";
		Template tpl = null;
		try {
			Map<String, Object> root = new HashMap<String, Object>();
			root.put("weatherInfo", weatherInfo);
			tpl = freeMarkerConfigurer.getConfiguration().getTemplate("weather.ftl");
			retSmsContent = FreeMarkerTemplateUtils.processTemplateIntoString(tpl, root);
		} catch (Exception e) {
			// TODO: handle exception
			logger.error("生成天气短信内容错误。"+e.getMessage());
		}
		return retSmsContent;
	}

}
