spring boot整合freemark

用过freemark的童孩都知道,freemark与spring的整合,需要在spring配置文件中配置freemrak的解析,原配置内容如下图:

<?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-3.0.xsd"       default-autowire="byName" default-lazy-init="false">    <!-- 设置freeMarker的配置文件路径 -->    <bean id="freemarkerConfiguration"          class="org.springframework.beans.factory.config.PropertiesFactoryBean">        <property name="location" value="classpath:freemarker.properties" />    </bean>    <!-- 配置freeMarker的模板路径 -->    <bean id="freemarkerConfig"          class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">        <!-- 指定FreeMarker模板文件目录 -->        <property name="freemarkerSettings" ref="freemarkerConfiguration" />        <property name="defaultEncoding" value="utf-8" />        <property name="templateLoaderPath" value="/WEB-INF/ftl/" />        <property name="freemarkerVariables">            <map>                <entry key="xml_escape" value-ref="fmXmlEscape"/>                <entry key="html_escape" value-ref="fmHtmlEscape"/>                <entry key="header_data" value-ref="headerHtmlEscape" />            </map>        </property>    </bean>        <bean id="headerHtmlEscape" class="com.xyy.shop.freemarker.HeaderFreemarkerTemplate" />  <bean id="fmXmlEscape" class="freemarker.template.utility.XmlEscape"/>    <bean id="fmHtmlEscape" class="freemarker.template.utility.HtmlEscape"/>     <!-- 配置freeMarker视图解析器 -->    <bean id="viewResolver"          class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">        <property name="viewNames" value="*"/>        <property name="prefix" value=""/>        <property name="suffix" value=""/>        <property name="cache" value="true" /><property name="contentType" value="text/html; charset=utf-8"/>        <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/>        <property name="requestContextAttribute" value="request"></property>    </bean></beans>

而在与spring boot的整合上,就显得要整洁很多了,不过默认的配置有没有之前的那么详细或可靠,这个就不从得知,还需要渗析,不废话了,回归话题

既然用到freemark肯定需要用到页面的,spring boot默认的页面文件夹为templates,此处我们就自定义了views,项目结构如下图所示:

依然pom.xml加入freemark与spring boot相关的依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-freemarker</artifactId></dependency>

src/main/resources/application.properties添加如下配置

#Freemarker配置spring.freemarker.template-loader-path=classpath:/views/spring.freemarker.cache=falsespring.freemarker.charset=UTF-8spring.freemarker.check-template-location=truespring.freemarker.content-type=text/htmlspring.freemarker.expose-request-attributes=truespring.freemarker.expose-session-attributes=truespring.freemarker.request-context-attribute=requestspring.freemarker.suffix=.ftl

这是我这块的配置，如果需要更多的 FreeMarker 配置，可以查看下面的详解

spring.freemarker.allow-request-override=false # Set whether HttpServletRequest attributes are allowed to override (hide) controller generated model attributes of the same name.spring.freemarker.allow-session-override=false # Set whether HttpSession attributes are allowed to override (hide) controller generated model attributes of the same name.spring.freemarker.cache=false # Enable template caching.spring.freemarker.charset=UTF-8 # Template encoding.spring.freemarker.check-template-location=true # Check that the templates location exists.spring.freemarker.content-type=text/html # Content-Type value.spring.freemarker.enabled=true # Enable MVC view resolution for this technology.spring.freemarker.expose-request-attributes=false # Set whether all request attributes should be added to the model prior to merging with the template.spring.freemarker.expose-session-attributes=false # Set whether all HttpSession attributes should be added to the model prior to merging with the template.spring.freemarker.expose-spring-macro-helpers=true # Set whether to expose a RequestContext for use by Spring's macro library, under the name "springMacroRequestContext".spring.freemarker.prefer-file-system-access=true # Prefer file system access for template loading. File system access enables hot detection of template changes.spring.freemarker.prefix= # Prefix that gets prepended to view names when building a URL.spring.freemarker.request-context-attribute= # Name of the RequestContext attribute for all views.spring.freemarker.settings.*= # Well-known FreeMarker keys which will be passed to FreeMarker's Configuration.spring.freemarker.suffix= # Suffix that gets appended to view names when building a URL.spring.freemarker.template-loader-path=classpath:/templates/ # Comma-separated list of template paths.spring.freemarker.view-names= # White list of view names that can be resolved.

其它相关的代码没任何变化.主要表现在controller需要返回一个页面,详细如下:

package com.xyy.controller;import java.util.HashMap;import java.util.Map;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.servlet.ModelAndView;import com.xyy.model.Favorite;import com.xyy.service.FavoriteService;/** * Favorite控制层 * @ClassName: FavoriteController  * @author wujing * @date 2017-07-13 15:09:50 */@RestController@RequestMapping("/favorite")public class FavoriteController{private static final Logger LOGGER = LoggerFactory.getLogger(FavoriteController.class);@Autowiredprivate FavoriteService favoriteService;/**     * Favorite编辑     * @Title: update     * @param favorite 修改对象     * @return Object     * @author wujing      * @date 2017-07-13 15:09:50     *///@RequestMapping("/detail2/{id}")public Object detail2(@PathVariable Long id,ModelMap modelMap) {Map<String,Object> resultMap = new HashMap<String,Object>();try {Favorite tempFavorite = favoriteService.selectByPrimaryKey(id);resultMap.put("status", "success");resultMap.put("data", tempFavorite);} catch (Exception e) {resultMap.put("status", "error");resultMap.put("errorMsg", "系统异常");LOGGER.error("Favorite添加异常", e);}return resultMap;}@RequestMapping("/detail/{id}")public Object detail(@PathVariable Long id,ModelMap modelMap) {try {Favorite tempFavorite = favoriteService.selectByPrimaryKey(id);modelMap.put("tempFavorite", tempFavorite);} catch (Exception e) {LOGGER.error("Favorite查询异常", e);}return new ModelAndView("favorite/detail");}}

detail.ftl文件内容:

<div>            <#if tempFavorite??>                ${tempFavorite.id }<br/>                ${tempFavorite.productId }<br/>                ${tempFavorite.merchantId }<br/>                ${tempFavorite.status }<br/>                ${tempFavorite.creator }<br/>                ${tempFavorite.createTime?string('yyyy-MM-dd HH:mm:ss') }            </#if>        </div>

右键运行main主入口,浏览器访问,如下图所示:

大功告成,页面出来的,是不是感觉奇丑无比,那就对了,接下来,看看,静态资源文件的配置吧;第五节:spring boot静态资源文件的访问以及自定义
