<!--1、继承  -->
<!--springboot开发必须继承org.springframework.boot文件  -->
<!--spring-boot-starter-parent使用后常见的包可以去掉version标签，避免版本冲突  -->

   	   <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.3.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
