githup项目 [https://github.com/wenrongyao/springboot\_freemarker][https_github.com_wenrongyao_springboot_freemarker]  master分支是最基础的整合，dev分支是freemarker的标签学习

目录结构

![70][]

1、pom.xml中添加freemarker依赖

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

2、配置application.properties,springboot项目有默认的配置，自己写了以后可以替代默认的配置。

spring.freemarker.allow-request-override=false
    spring.freemarker.cache=true
    spring.freemarker.check-template-location=true
    spring.freemarker.charset=UTF-8
    spring.freemarker.content-type=text/html
    spring.freemarker.expose-request-attributes=false
    spring.freemarker.expose-session-attributes=false
    spring.freemarker.expose-spring-macro-helpers=false
    server.port = 8090

3、HelloController,映射配置和数据填充

import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    
    /**
     * @author rongyaowen
     */
    @Controller
    public class HelloController {
    
        @RequestMapping("/hello")
        public String hello(Model model) {
            model.addAttribute("name", "kangkang");
            return "hello";
        }
    
    }

4、模板文件，htllo.ftl

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    </head>
    <body>
        Hello ${name}
    </body>
    </html>

5、springboot启动类

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;
    
    /**
     * @author rongyaowen
     */
    @SpringBootApplication
    @ComponentScan("com.wry.controller")
    public class SpringBootSampleApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(SpringBootSampleApplication.class, args);
    
        }
    }

结果展示，模板中的$\{name\}已经被替换
