И мой файл шаблона hello.ftl, как показано ниже

<html>
<head>
    <title>welcome</title>
</head>
<body>
    <h1>Hello ${hello}</h1>
</body>

And my SparkRoutes.java looks as below,

package com.mongodb.week1.lesson13;

import spark.ModelAndView;
import spark.Request;
import spark.Response;
import spark.template.freemarker.FreeMarkerEngine;

import java.util.HashMap;
import java.util.Map;

import static spark.Spark.get;

 public class SparkRoutes {

    public static void main(String[] args) {
        get("/", (Request req, Response res) -> {
            Map<String, String> attributes = new HashMap<>();
            attributes.put("hello", "Hello World spark freemarker !");
            return new ModelAndView(attributes, "hello.ftl");
        }, new FreeMarkerEngine());
    }


}
