### SpringBoot概述 ###

Spring Boot是一个便捷搭建 基于spring工程的脚手架；作用是帮助开发人员快速搭建大型的spring 项目。简化工程的配置，依赖管理；实现开发人员把时间都集中在业务开发上。

### SpringBoot构建 ###

##### 1.创建Maven工程 #####

##### 2.添加依赖 #####

添加父工程

<parent>
            <artifactId>spring-boot-starter-parent</artifactId>
            <groupId>org.springframework.boot</groupId>
            <version>2.1.5.RELEASE</version>
        </parent>

添加启动器依赖

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

##### 3.构建启动类 #####

import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * spring boot 工程的启动引导类，工程的入口
     */
    @SpringBootApplication
    public class Application {
        
        public static void main(String[] args){
        
            SpringApplication.run(Application.class,args);
        }
    
    }

##### 4. 创建控制器Controller #####

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 springboot";
        }
    }

##### 5. 测试 #####

访问 http://localhost:8080/hello
