2. 系統變量Path添加兩個變量(win10分開添加)
    %JAVA_HOME%\bin；
    %JAVA_HOME%\jre\bin；

    變量值：D:\tomcat\apache-tomcat-8.5.43-windows-x64\apache-tomcat-8.5.43
2. 系統變量Path添加變量 (bin目錄)
    D:\tomcat\apache-tomcat-8.5.43-windows-x64\apache-tomcat-8.5.43\bin

3、maven

1. 下載、解壓
2. 環境變量配置
    變量名：MAVEN_HOME
    變量值：D:\maven\apache-maven-3.3.9-bin\apache-maven-3.3.9
3. 系統變量Path添加變量 (bin目錄)--驗證 mvn -v
    D:\maven\apache-maven-3.3.9-bin\apache-maven-3.3.9\bin
4. 配置本地倉庫
    新建文件夾maven_repository作爲本地倉庫
    修改配置文件D:\maven\apache-maven-3.3.9-bin\apache-maven-3.3.9\conf\setting.xml :
      <localRepository>D:\maven\maven_repository</localRepository>
5. 添加鏡像
<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>
