1，maven坐标

   <dependency>

    <title>Freemarker入门小DEMO </title>
</head>
<body>
<#--我只是一个注释，我不会有任何输出  -->
${name},你好。${message}<br/>

<#if success??>
  你已通过实名认证
<#else>
  你未通过实名认证

pojo

public class Person {
    private String name;
    private String message;
    private String success;

import com.freemark.pojo.Person;
import freemarker.template.Configuration;
import freemarker.template.Template;
import freemarker.template.TemplateException;

import java.io.*;

public class FreemarkMain {
    public static void main(String[] args) throws IOException, TemplateException {
        //1.创建配置类
        Configuration configuration=new Configuration(Configuration.getVersion());
        //2.设置模板所在的目录
        configuration.setDirectoryForTemplateLoading(new File("src/main/resources/templates/"));
        //3.设置字符集
        configuration.setDefaultEncoding("utf-8");
        //4.加载模板
        Template template = configuration.getTemplate("index.ftl");
        //5.创建数据模型
        Person person = new Person();
        person.setName("小苏");
        person.setSuccess("");
        person.setMessage(null);
        //6.创建Writer对象
//        Writer out =new FileWriter(new File("d:\\test.html"));
        Writer out = new OutputStreamWriter(System.out);
        //7.输出
        template.process(person, out);
