在子pom中添加基本依赖 （srping boot项目）是不是可以不用版本号 因为父级项目以及有了约束

    
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
            org.springframework.boot
            spring-boot-starter-actuator
        
        
            mysql
            mysql-connector-java
        
    

在resources下创建application.yml

在yml中设置启动端口

server:
  port: 8080

 最后创建一个启动入口类（名字自拟）

@SpringBootApplication
public class OrderApplication {
    public static void main(String[] args) {
        SpringApplication.run(OrderApplication.class,args);
    }
}

最后附上项目总体预览图
