问题描述：
IDEA导入maven项目后，下载jar包的时候，控制台报错，报错信息如下：
org.springframework.boot:spring-boot-starter-parent:pom:2.7.3 failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.7.3 from/to central (https://repo.maven.apache.org/maven2): transfer failed for https://repo.maven.apache.org/maven2/org/springframework/boot/spring-boot-starter-parent/2.7.3/spring-boot-starter-parent-2.7.3.pom

原因：
没有设置IDEA中的maven配置，还是默认的样子，所以IDEA会自然地去“https://repo.maven.apache.org/maven2”这个路径找jar包，那么就会出现解析不了的情况

解决方案：
修改IDEA的maven配置即可，修改后如下：

然后重新加载依赖，即可解决
