springboot集成freemarker【JWordPress前台项目实战】

写在前面

通过前面几篇文章,我么已经可以搭建后台通用一个增删改查框架,这节课我们主要讲如何如前端页面交互。通常的做法一般分为2种:

  1. 后端提供restfull接口,前端页面由专业的前端开发人员去做,这样子适合前后端分离
  2. 后台开发包圆前端页面的开发任务,通过cotroller 实现于视图层的交互

两种方法各有优劣,今天我们要讲的是第二种:如何在springboot应用中集成freemarker?

代码

引入xml

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

freemarker配置类

 WebConfig config = new WebConfig();
 Map<String,String> map =(Map<String, String>) redisTemplate.opsForValue().get(RedisConstant.autoloadConfig);
 config.setHomeDesc(map.get("homeDesc"));
 config.setHomeKeywords(map.get("homeKeywords"));
 config.setSiteName(map.get("blogname"));
 config.setSiteUrl(map.get("siteurl"));
 model.addAttribute("config", config);
 SeoVO seoVO = new SeoVO();
 seoVO.setTitle("HARRIES BLOG™-追心中的海,逐世界的梦");
 seoVO.setKeywords("IT教程,互联网资讯,创业资讯,知识问答,生活感悟,编程技术,运维管理,分布式缓存,开发框架,数据库,集成工具,投资资讯,自动化,操作系统, 虚拟化,监控软件");
 seoVO.setDescription("HARRIES BLOG™是国内领先的IT技术博客,分布式缓存博客,编程技术博客,创业指导博客,IT投资资讯博客,IT运维博客,IT教程博客,互联网资讯博客,,云");
 model.addAttribute("seoVO", seoVO);
