四、添加文件

 
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

        <artifactId>spring-boot-starter-parent</artifactId>

    <build>
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>

</project>

 

配置默认application.properties
# 设定ftl文件路径
spring.freemarker.template-loader-path=classpath:/templates
spring.freemarker.suffix=.ftl

#spring.freemarker.cache=false
#spring.freemarker.charset=UTF-8
#spring.freemarker.check-template-location=true
#spring.freemarker.content-type=text/html
#spring.freemarker.expose-request-attributes=false
#spring.freemarker.expose-session-attributes=false
#spring.freemarker.request-context-attribute=request

 

实现WelcomController
package org.ouyushan.springboot.web.freemarker.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.Date;
import java.util.Map;

/**
 * @Description:
 * @Author: ouyushan
 * @Email: ouyushan@hotmail.com
 * @Date: 2020/4/30 11:35
 */
@Controller
public class WelComeController {

    @Value("${application.message:Default Value Hello World}")
    private String message;

    @GetMapping("/")
    public String error(Map<String,Object> model){
        model.put("index",this.message);
        return "index";
    }

    @GetMapping("/hi")
    public String welcome(Model model){
        model.addAttribute("time",new Date());
        model.addAttribute("message",this.message);
        return "hello";
    }
}

 

添加页面文件
templates/hello.ftl
<!DOCTYPE html>

<html lang="en">

<body>
    Date: ${time ? date}
<br>
    Time: ${time ? time}
<br>
    Message: ${message}
</body>

</html>

 

templates/index.ftl
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
this is index ${index}
</body>
</html>


五、接口测试


访问：


http://localhost:8080/


 




访问：


http://localhost:8080/hi




六、知识点


必须配置以下内容，否则报 no mapping found for ** 错误




spring.freemarker.template-loader-path=classpath:/templates
spring.freemarker.suffix=.ftl
