首先新建个 maven 项目
菜单 -> File -> New -> Other -> Maven -> Maven -> Maven Project -> New Maven Project
勾上这个 Create a simple project (skip archetype selection),

Springboot就是个简单的maven 项目

设置下面参数（自己写）

用下面的pom.xml数据覆盖项目里的

<?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"

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

再在src下创建一个Application.java文件(有点类似Jfinal里的run里的JfinalConfig启动文件)

package springboot;

 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
 
@SpringBootApplication
public class Application {
 
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
 
}

创建一个HelloController.java（控制器）文件

package springboot;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
 
@RestController
public class HelloController {
 
    @RequestMapping("/hello")
    public String hello() {
        return "Hello Spring Boot!";
    }
 
}

再运行Application.java文件。

通过http://127.0.0.1:8080/hello 访问
