④：将domain实体类分为单独模块开发

⑤：将分开的项目包install到仓库

二、依赖管理

①：依赖传递

②：可选依赖与排除依赖

三、 继承与聚合

①：聚合

②：继承

③：继承和聚合的区别

四、属性

①：属性

②：配置文件加载属性

    <build>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>

③：版本管理

五、多环境配置与应用

①：多环境开发

②：跳过测试

            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <version>2.22.1</version>
                <configuration>
<!--                    是否跳过测试 false -->
                    <skipTests>false</skipTests>
<!--                    排除掉不参与测试的内容-->
                    <excludes>
                        <exclude>**/BookServiceTest.java</exclude>
                    </excludes>
                </configuration>

六、私服

①：私服介绍

②：私服安装（Nexus）

• Nexus

  • Sonatype公司的一款maven私服产品
  • 下载地址 ：https://help.sonatype.com/repomanager3/product-information/download

• 网盘下载

  • 链接：https://pan.baidu.com/s/1RGoB1pP7-RzkR9nm3n6ILA
  • 提取码：Coke

• ①. 使用管理员运行cmd
• ②.进入nexus-2.14.11-01\bin目录中执行以下命令

nexus.exe /install <optional-service-name> //安装服务   
(optional-service-name是服务别名，默认是nexus)
nexus.exe /uninstall //卸载服务
 
nexus.exe /start <optional-service-name> //启动服务
nexus.exe /stop <optional-service-name>  //停止服务

扩展：
可以安装多个服务名不同的服务，分别启动
nexus.exe /install nexus01 //安装服务
nexus.exe /start nexus01 //启动服务
nexus.exe /install nexus02 //安装服务
nexus.exe /start nexus02 //启动服务

③：修改基本配置信息

④：私服仓库分类

⑤：本地仓库访问服务配置

01. 新建仓库

|

02. 配置是否允许重新发布

03.添加阿里中央仓库

• 阿里中央仓库地址 http://maven.aliyun.com/nexus/content/groups/public/

04. 配置本地仓库访问私服的权限

	
	<server>
		 <id>coke-Releaseid> 
		 <username>adminusername> 
		 <password>admin123password> 
	server>

	<server>
		 <id>coke-Snapshotid> 
		 <username>adminusername> 
		 <password>admin123password> 
	server>
	
	<server>
		 <id>aliyunid> 
		 <username>adminusername> 
		 <password>admin123password> 
	server>

05. 配置映射（私服的地址URL）

	  
	 <mirror>
		<id>maven-publicid>  
		<mirrorOf>*mirrorOf> 
		<url>http://localhost:8081/repository/maven-public/url>
	mirror>

⑥：私服资源上传与下载

    
    <distributionManagement>
        
        <repository>
            <id>coke-Releaseid>
            <url>http://localhost:8081/repository/coke-Release/url>
        repository>
        
        <snapshotRepository>
            <id>coke-Snapshotid>
            <url>http://localhost:8081/repository/coke-Snapshot/url>
        snapshotRepository>
