一、创建好SpringBoot项目后系统默认添加了spring-boot-starter-parent配置。

1    <parent>
2         <groupId>org.springframework.boot</groupId>
3         <artifactId>spring-boot-starter-parent</artifactId>
4         <version>2.4.4</version>
5         <relativePath/> <!-- lookup parent from repository -->
6     </parent>

spring-boot-starter-parent提供了如下默认配置：

1、java默认使用版本。

2、编码格式默认使用UTF-8。

3、提供了dependencyManagement,使开发者在引入其他依赖时不必输入版本号，方便依赖管理。

4、默认的资源过滤与插件配置。

二、开发web项目需要引入一个web的starter

1  <dependencies>
2         <dependency>
3             <groupId>org.springframework.boot</groupId>
4             <artifactId>spring-boot-starter-web</artifactId>
5         </dependency>
6 
7     </dependencies>

三、手动查找添加依赖 https://mvnrepository.com/
