SpringBoot2.0.2 不使用parent作为maven单继承方式操作 : org.springframework.boot : spring-boot-dependencies : 2.0.2.RELEASE

1、pom配置方式

2、实体类编写

 1 package com.springboot;
 2 
 3 import org.springframework.boot.SpringApplication;
 4 import org.springframework.boot.autoconfigure.SpringBootApplication;
 5 import org.springframework.context.ConfigurableApplicationContext;
 6 import org.springframework.context.annotation.Bean;
 7 
 8 /******************************

10  * @ClassName : QuickStartApplication

12  * @Time : 01:05:59

18 
19 @SpringBootApplication
20 public class QuickStartApplication {
21 
22     @Bean
23     public Runnable createRunnable() {
24 
25         return () -> {
26             System.out.println("Spring Boot is Run");
27         };
28 
29     }
30 
31     public static void main(String[] args) {
32         ConfigurableApplicationContext applicationContext = SpringApplication.run(QuickStartApplication.class,args);
33         applicationContext.getBean(Runnable.class).run();
34     }
35 }

这个在官方文档上也有具体写:
