SpringMVC+FreeMarker的使用

之前用Java写Web都是用的HTML静态页面，重复的代码很多，基本是都是复制的，让人看起来很乱而且不好维护，FreeMarker使得代码更加整洁、更易维护，而且简化了后端的处理逻辑，简单易上手，下面介绍一下基本使用方法。

一、POM 中增加依赖

        <dependency>            <groupId>org.freemarker</groupId>            <artifactId>freemarker</artifactId>            <version>2.3.23</version>        </dependency>

二、在xml配置bean

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">    <bean id="freemarkerConfig"          class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">        <property name="templateLoaderPath" value="/WEB-INF/view/" />        <property name="freemarkerSettings">            <props>                <prop key="template_update_delay">0</prop>                <prop key="default_encoding">UTF-8</prop>                <prop key="number_format">0.##########</prop>                <prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>                <prop key="classic_compatible">true</prop>                <prop key="template_exception_handler">ignore</prop>            </props>        </property>    </bean>    <bean id="viewResolver"          class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">        <property name="suffix">            <value>.ftl</value>        </property>        <property name="contentType" value="text/html;charset=UTF-8"></property>    </bean></beans>

三、模板文件示例，ftl文件，freemarker.ftl

<!DOCTYPE html><html><head>    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">    <title>${title}</title></head><body>${content}</body></html>

四、Controler示例，通过ModelAndView引用一个模板，使用的时候名字不带后缀

@Controller@RequestMapping("/index/")public class FreeMarkerController {    private Logger LOGGER = LoggerFactory.getLogger(FreeMarkerController.class);    //批量更新DQC数据用的    @RequestMapping(value = "test", produces = "text/plain;charset=UTF-8",            method = RequestMethod.GET)    public ModelAndView freeMarkerTest() {        ModelAndView mv = new ModelAndView("freemarker");        mv.addObject("title", "Spring MVC And Freemarker");        mv.addObject("content", " Hello world ， test my first spring mvc ! ");        return mv;    }}
