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：

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
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>
