除了在eclipse自带的软件商店下载Spring Tool来自动创建Spring Boot之外
我们也可以使用Maven拉搭建
第一步：new-other-maven project

这样一个简单的maven已经搭建完毕目录结构如下

接着我们需要在pom文件中添加springboot的依赖
配置文件如下：

等待一段时间后，会发现已经添加好了maven依赖

在main中创建一个包，写一个hello springboot

package com.edu.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class Hello {
	 @RequestMapping("/")
	 public String hello() {
		 return "hello springboot";

}
}

然后在mian中直接创建一个App,这类似于一个开关

package com.edu.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {

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

}

要是报错的话排除自动注入

package com.edu.controller;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
public class App {

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

}

运行结果：
