pom.xml:

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <!-- jdk版本号，angel在这里使用1.8，大家修改为大家本地配置的jdk版本号即可 -->
    <java.version>1.8</java.version>
</properties>

<parent>
    <groupId>org.springframework.boot</groupId>

启动类：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;

@Controller
@SpringBootApplication
public class Main {
@RequestMapping("/")
public String hello(Map<String,Object> map){
    map.put("name","lijia");
    return "hello";
}

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

hello.ftl

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