import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;

@SpringBootApplication
public class Application  extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

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

}

五、HelloController.java

package com.airkisser;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;

import java.util.Date;

@Controller
public class HelloController {

    @GetMapping("/")
    public String hello(Model model){
        model.addAttribute("date",new Date());
        model.addAttribute("message","Hello Freemarker.");
        return "welcome";
    }

}

六、welcome.ftl

<#-- @ftlvariable name="request" type="javax.servlet.http.HttpServletRequest" -->
<#-- @ftlvariable name="date" type="java.util.Date" -->
<#-- @ftlvariable name="message" type="java.lang.String" -->
<#assign contentPath=request.contextPath>
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Welcome</title>
</head>
<body>
ContentPath: ${contentPath}
<br>
Date: ${date?datetime}
<br>
${message}
</body>
</html>

七、結果
