# 二、DemoApplication #

package com.william;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    /**
     * @author ：lijunxuan
     * @date ：Created in 2019/6/27  16:34
     * @description ：
     * @version: 1.0
     */
    
    /**
     * SpringBootApplication
     * 代表当前类是一个SpringBoot的启动引导类
     */
    @SpringBootApplication
    public class DemoApplication {
        public static void main(String[] args) {
            // SpringApplication.run启动当前的Spring应用
            //第一个参数：当前类的字节码文件
            //第二个参数：主函数的参数
            SpringApplication.run(DemoApplication.class,args);
        }
    }

# 三、controller #

package com.william.controller;
    
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @author ：lijunxuan
     * @date ：Created in 2019/6/27  16:45
     * @description ：
     * @version: 1.0
     */
    @RestController
    public class HelloController {
        @RequestMapping("/hello")
        public  String hello() {
            return "hello World";
        }
    }
