在eclipse中点击window--->preferences--->maven--->installaation

选择usersettings进行配置

之前的配置都是将镜像地址写成http://maven.aliyun.com/nexus/content/groups/public/，不知从什么时候开始并没什么卵用，现在将地址换成：

http://121.42.166.202:8081/nexus/content/groups/public

具体如pom.xml

<?xml version="1.0"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <!--本地镜像库，根据自己需要设置-->
