新公司的一个CMS项目要用到，这里记录下
一、项目文件图
二、springmvc-servlet.xml 添加
<!-- 定义环境变量文件 --> ???<bean id="propertyHolder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> ???????<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/> ???????<property name="ignoreResourceNotFound" value="true"/> ???????<property name="locations"> ???????????<list> ???????????????<value>classpath*:/*.properties</value> ???????????</list> ???????</property> ???</bean>
三、html_template.vm
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html> ???<head> ???????<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> ???????<title>${list.title}</title> ???</head> ???<body> ???????<h2>${list.title}</h2> ???????<table border="1" style="margin-left: 100px" > ???????????<tr> ???????????????<th class="jobs-time">序号</th> ???????????????<th class="jobs-title">名称</th> ???????????????<th class="jobs-title">mobileNo</th> ???????????????<th class="jobs-title">email</th> ???????????</tr> ???????????#if($!list) ???????????????<tr> ???????????????????<td>${list.userId}</td> ???????????????????<td>${list.userName}</td> ???????????????????<td>${list.mobile}</td> ???????????????????<td>${list.email}</td> ???????????????</tr> ???????????#end ???????</table> ???</body></html>四、控制器
package com.geenk.web.controller.generatehtml;import com.geenk.web.velocity_engine.GenerateHtmlUtil;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import java.util.HashMap;import java.util.Map;/** * @author DUCHONG * @since 2018-04-28 18:51 **/@Controllerpublic class GenerateController { ???@Value("${filePath}") ???private String filePath; ???@Value("${templatePath}") ???private String templatePath; ???@ResponseBody ???@RequestMapping(value = "/html",method = RequestMethod.GET) ???public String generateHtml(){ ???????//一般这里是数据库查出的记录的list,然后遍历list,逐个生成html，存放路径，一般是取 "配置+表字段值"，作为存放的路径 ???????//这里用for代替 ???????for(int i=1;i<10;i++){ ???????????//页面要展示的数据 ???????????Map<String,Object> map=new HashMap<>(); ???????????map.put("title","news"+i); ???????????map.put("userId",i); ???????????map.put("userName","test"+i); ???????????map.put("mobile","18106519020"); ???????????map.put("email","1427222829@qq.com"); ???????????GenerateHtmlUtil.generateHtmlByVelocity("news"+i,filePath,templatePath,map,"list"); ???????} ???????return "Over"; ???}}五、工具类
package com.geenk.web.velocity_engine;import org.apache.velocity.Template;import org.apache.velocity.VelocityContext;import org.apache.velocity.app.Velocity;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import java.io.BufferedWriter;import java.io.File;import java.io.FileOutputStream;import java.io.OutputStreamWriter;import java.util.Properties;/** * @author DUCHONG * @since 2018-04-28 18:35 **/public class GenerateHtmlUtil { ??static Logger logger = LoggerFactory.getLogger(GenerateHtmlUtil.class); ???/** ????* 通过velocity 模板生成静态HTML 文件 ????* @param fileName 生成的文件的文件名称 ????* @param filePath 保存文件位置 ????* @param templatePath velocity模板文件路径 ????* @param params 集合 ????* @param pageName 页面上需要便利或者使用的变量，可以为任意值 ????*/ ???public ?static void generateHtmlByVelocity(String fileName, String filePath, ?????????????????????????????????????String templatePath, Object params, String pageName){ ???????String finalFilePath=filePath+ File.separator+fileName+".html"; ???????try { ???????????//设置加载模版文件的方式，在classpath 下面查找 ???????????Properties p = new Properties(); ???????????p.put("file.resource.loader.class", ???????????????????"org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader"); ???????????Velocity.init(p); ???????????FileOutputStream fos = new FileOutputStream(finalFilePath); ???????????BufferedWriter writer ?= new BufferedWriter(new OutputStreamWriter( ???????????????????fos, "utf8")); ???????????Template velocity_template = Velocity.getTemplate(templatePath,"utf8"); ???????????VelocityContext context = new VelocityContext(); ???????????context.put(pageName, params); ???????????velocity_template.merge(context,writer); ???????????writer.close(); ???????} ???????catch (Exception e) { ???????????logger.error("文件路径失败！",e); ???????} ???}}六、运行
浏览器输入localhost:8866/html,显示Over
Velocity根据模版生成静态html
