FreeMarker是一款模板引擎：即一种基于模板和要改变的数据，并用来生成输出文本（HTML网页、电子邮件、配置文件、源代码等）的通用工具。它不是面向最终用户的，而是一个Java类库，是一款程序员可以嵌入他们所开发产品的组件。–百度百科

首先pom.xml导入freemarker依赖

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

跟Spring Boot整合Jsp该篇文章类似，一个实体类用户返回结果，controller和启动类。

Student.java

package xyz.xioaxin12.springboot.controller.student;

public class Student {
    private Integer id;
    private String name;
    private int age;

    public Student() {
    }

    public Student(Integer id, String name, int age) {
        this.id = id;
        this.name = name;
        this.age = age;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

StudentController .java

package xyz.xioaxin12.springboot.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import xyz.xioaxin12.springboot.controller.student.Student;

import java.util.ArrayList;
import java.util.List;

@Controller
public class StudentController {
    @RequestMapping("/show")
    public String showStudent(Model model){
        List<Student> list = new ArrayList<>();
        list.add(new Student(1,"小信",22));
        list.add(new Student(2,"天天",25));
        list.add(new Student(1,"赵六",20));
        model.addAttribute("list",list);
        return "show";
    }
}

启动类

package xyz.xioaxin12.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author 爱生活爱技术
 */
@SpringBootApplication
public class SpringBoot04FreemarkerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBoot04FreemarkerApplication.class, args);
    }

}

最后编写视图

注意：模板形式的文件必须放在templates下，外界不可直接访问的！

<html>
    <head>
        <title>freemarker</title>
        <meta charset="utf-8"/>
    </head>

    <body>
        <table border="2" align="center" width="50%">
            <tr>
                <th>ID</th>
                <th>姓名</th>
                <th>年龄</th>
            </tr>

            <#list list as s>
                <tr>
                    <td>${s.id}</td>
                    <td>${s.name}</td>
                    <td>${s.age}</td>
                </tr>
            </#list>
        </table>

    </body>
</html>
