加快maven中jar包的下载速度

　　maven下载jar包的默认仓库是http://my.repository.com/repo/path速度较慢，通过配置国内镜像提高下载速度

1.打开eclipse--->Window--->Preferences--->选择Maven下的User Settings 如图找到User Settings路径中的settings.xml文件

2.使用notepad++等文本编辑器打开文件进行修改

 <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>

   </mirror>

   <mirror>
     <id>nexus</id>
     <name>internal nexus repository</name>
     <!-- <url>http://192.168.1.100:8081/nexus/content/groups/public/</url>-->
     <url>http://repo.maven.apache.org/maven2</url>
     <mirrorOf>central</mirrorOf>
   </mirror>

 </mirrors>
