## SpringBoot两种启动方式 ##

### 第一种启动方式在控制器中通过@EnableAutoConfiguration注解进行启动 ###

package com.zuojie.Controller;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * 功能描述：第一个SpringBoot
     * Author:zuojie
     */
    @RestController //Controller+ResponseBody注解
    @EnableAutoConfiguration
    public class HelloWorld {
        @RequestMapping("/hello")
        public String hello(){
            return "success";
        }
    
        public static void main(String[] args) {
            //开始运行
            SpringApplication.run(HelloWorld.class, args);
        }
    
    
    }

### 第二种启动方式通过@ComponentScan(basePackages = “com.zuojie.controller”)—控制器扫包范围 ###

package com.zuojie.Controller;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.context.annotation.ComponentScan;
    
    /**
     * author:zuojie
     */
    
    @EnableAutoConfiguration
    @ComponentScan("com.zuojie.Controller")
    public class App {
        public static void main(String[] args) {
            SpringApplication.run(App.class,args);
        }
    }
