**1. 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>2.1.6.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

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

**2.编写****SpringBoot****引导类**

要通过SpringBoot提供的引导类起步SpringBoot才可以进行访问

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

**3.编写****Controller**

在引导类MySpringBootApplication同级包或者子级包中创建QuickStartController

package com.qst.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    @Controller
    public class SpringBootController {
        @RequestMapping("/hello")
        @ResponseBody
        public String quick(){ return "springboot 环境搭建成功!"; }
    }

运行后控制台打印可见如下

通过日志发现，Tomcat started on port(s): 8080 (http) with context path ''

tomcat已经起步，端口监听8080，web应用的虚拟工程名称为空

打开浏览器访问url地址 [http://127.0.0.1:8080/hello][http_127.0.0.1_8080_hello]
