一、SpringBoot整合FreeMarker

1.1导入依赖

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

1.2在application.properties文件添加配置

########## 配置freemarker ##########
#是否开启缓存
spring.freemarker.cache=false
#路径
spring.freemarker.template-loader-path=classpath:/templates
#文件后缀
spring.freemarker.suffix=.ftl

spring.freemarker.charset=UTF-8
spring.freemarker.content-type=text/html

1.3创建实体类

package com.qf.pojo;

public class Student {

    private Integer id;
    private String name;
    private Integer age;

    private String address;

    public Student(Integer id, String name, Integer age, String address) {

        this.id = id;
        this.name = name;
        this.age = age;
        this.address = address;
    }

    public Student() {
    }

    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 Integer getAge() {
        return age;
    }

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

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }
}

1.4在templates目录下创建student.ftl文件（然后把该ftl文件拷贝到D:/ftl目录下，一会用）

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
    <table border="1" width=600>
        <tr>
            <th>index</th>
            <th>id</th>
            <th>name</th>
            <th>age</th>
            <th>address</th>
        </tr>
        <#list students as student>
            <#if student_index % 2 == 0>
            <tr bgcolor="red">
                <#else>
            <tr bgcolor="yellow">
            </#if>
            <td>${student_index}</td>
            <td>${student.id}</td>
            <td>${student.name}</td>
            <td>${student.age}</td>
            <td>${student.address}</td>
            </tr>
        </#list>
    </table>
</body>
</html>

1.5创建controller

package com.qf.controller;

import com.qf.pojo.Student;
import freemarker.template.Configuration;
import freemarker.template.Template;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.FileWriter;
import java.util.ArrayList;
import java.util.HashMap;

@Controller
@RequestMapping("/freemarker")
public class FreeMarkerController {

    @RequestMapping("/student")
    public String hello(Model model) throws Exception {

        //创建List集合获取多个元素
        ArrayList<Student> students = new ArrayList<>();
        students.add(new Student(1, "jack", 18, "郑州二七"));
        students.add(new Student(2, "rose", 19, "郑州中原"));
        students.add(new Student(3, "tom", 20, "郑州金水"));

        model.addAttribute("students",students);

        return "/student";
    }

    //生成静态页面的方法
    @RequestMapping("createHtml")
    @ResponseBody
    public String createHtml()throws Exception{
        //获取配置对象
        Configuration configuration = new Configuration(Configuration.DEFAULT_INCOMPATIBLE_IMPROVEMENTS);
        //设置字符集
        configuration.setDefaultEncoding("utf-8");

        //设置加载的模版目录
        configuration.setDirectoryForTemplateLoading(new File("D:/ftl"));
        //创建List集合获取多个元素
        ArrayList<Student> students = new ArrayList<>();
        students.add(new Student(1,"张三",18,"北京"));
        students.add(new Student(2,"李四",19,"上海"));
        students.add(new Student(3,"王五",20,"广州"));

        //使用map集合加载数据
        HashMap<String,ArrayList> map = new HashMap<>();
        map.put("students",students);

        //创建输出流对象
        FileWriter fileWriter = new FileWriter(new
                File("D:/ftl_html/student.html"));

        //获取加载的模板
        Template template = configuration.getTemplate("student.ftl");
        //生成html文件
        template.process(map,fileWriter);
        //关流
        fileWriter.close();

        return "success";
    }

}
