同学你好，老师这边并没有报错，建议同学在pom.xml中添加镜像，如下：

<repositories>
	<repository>
		<id>huaweicloud</id>
		<name>huawei maven</name>
		<url>https://mirrors.huaweicloud.com/repository/maven/</url>
	</repository>
</repositories>

更新一下maven依赖，项目右击选择maven，update project，如下：

重新打开pom.xml。

如果问题没有解决，建议同学下载课程源码，使用课程源码试试。

祝学习愉快~

试过了，不行，好像是pom.xml的第一行的那些配置有问题，一直报错，都不知道是不是有什么没有被下载
