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;
} }
