Spring Tool Suite uses slow-to-bring maven---Modify the settings.xml update Mirror method

(1) Open sts,windows-"preference, find Maven, and set the following.

(2) Modify the document as follows

<?xml version= "1.0" encoding= "UTF-8"?>
<settings xmlns= "http://maven.apache.org/POM/4.0.0" xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemalocation= "http://maven.apache.org/POM/4.0.0/HTTP// Maven.apache.org/xsd/settings-1.0.0.xsd ">
      <mirrors>
      	<mirror>      
          <id>repo2</id >      
          <mirrorOf>central</mirrorOf>      
          <name>human readable name for this mirror.</name>      
          <url>http://repo2.maven.org/maven2/</url>
        </mirror>
      </mirrors>

</ Settings>

Reopen the STS, right-click on Pom.xml, Run as, maven Clean,maven install.

Can be a little faster.
