springboot依赖导入失败

IDEA导入SpringBoot项目全部报错，依赖找不到

 

恶心。。。。。。。

两天了。就因为我把repository删除了。然后想重新下过。更新一下项目。但是发现我做了任何的配置，设置。导包。clear。等等等。都没用。

发现，是我家宽带有限制，下不来。然后我设置镜像，就可以了。

方案一：在maven中settings配置阿里镜像

  <mirrors>
    <!-- mirror
     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
     |
    <mirror>
      <id>mirrorId</id>
      <mirrorOf>repositoryId</mirrorOf>
      <name>Human Readable Name for this Mirror.</name>
      <url>http://my.repository.com/repo/path</url>
    </mirror>
     -->
    <mirror>  
     <id>alimaven</id>  
     <name>aliyun maven</name>  
     <url>http://maven.aliyun.com/nexus/content/groups/public/</url>  
     <mirrorOf>central</mirrorOf>          
   	</mirror> 
  </mirrors>

方案二：在项目的pom.xml中配置镜像（阿里）

    </build>

    <repositories>
        <repository>
            <id>alimaven</id>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
        </repository>
    </repositories>

</project>
