1.使用idea工具创建一个maven工程，该工程为普通的java工程即可

2. 添加SpringBoot的起步依赖

SpringBoot要求，项目要继承SpringBoot的起步依赖spring-boot-starter-parent

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.1.RELEASE</version>
</parent>

SpringBoot要集成SpringMVC进行Controller的开发，所以项目要导入web的启动依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

3.写SpringBoot引导类

package com;

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


//标注SpringBoot的启动类  组合注解
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
//        代表运行SpringBoot的启动类，参数为SpringBoot启动类的字节码对象
        SpringApplication.run(Application.class,args);
    }
}

4. 编写Controller

package com;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {

    @RequestMapping("/hello")
    @ResponseBody
    public String hello(){
        return "hello, spring boot!";
    }
}

5.执行SpringBoot起步类的主方法
