报错信息显示Maven无法从默认的远程仓库地址http://maven.oschina.net/content/groups/public下载依赖包。所以要解决的就是把远程仓库地址换一下。推荐使用阿里云的远程仓库。

要更换默认远程仓库地址需要找到.m2文件夹下面的settings.xml文件。一般都是在C:\Users\Administrator\.m2下面。（开始我改的maven/conf目录下面的settings.xml文件但是没有用，所以需要改.m2文件夹下面的）找到之后打开，将原来默认远程仓库地址http://maven.oschina.net/content/groups/public改为阿里云mavaen仓库地址http://maven.aliyun.com/nexus/content/groups/public之后保存即可。如下图
