项目pom中要想包含子模块，需要配置modules其中module是子模块的artifactId值
<modules> <module>qar-commonsmodule> <module>qar-gatewaymodule> <module>qar-monitormodule> <module>qar-authmodule> <module>qar-adminmodule> <module>qar-modulemodule> <module>qar-newmodule> modules>- 1

子模块想要继承父级模块的dependency依赖包，需要配置parent指定继承节点
<parent> <groupId>io.qargroupId> <artifactId>qar-cloudartifactId> <version>${revision}version> parent>- 1
- 2
- 3
- 4
- 5
每一个模块必须要有groupId、artifactId、packaging、version：
<groupId>io.qargroupId> <artifactId>qar-commonsartifactId> <packaging>pompackaging>- 1
- 2
- 3
每个模块的变量先在当前配置中查找，如果没有就去父模块查找：
<version>${revision}version>- 1
属性变量的配置：
<properties> <revision>3.10.0revision> <project.build.sourceEncoding>UTF-8project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8project.reporting.outputEncoding> <java.version>1.8java.version> <spring.cloud.version>2021.0.5spring.cloud.version> <spring.cloud.alibaba.version>2021.0.4.0spring.cloud.alibaba.version> properties>- 1

repositories 远程仓库配置：
唯一的ID，一个描述性的name，远程仓库的url, true告诉Maven可以从这个仓库下载releases版本的构件
<repositories> <repository> <id>publicid> <name>aliyun nexusname> <url>https://maven.aliyun.com/repository/public/url> <releases> <enabled>trueenabled> releases> repository> repositories>- 1

pluginRepositories远程插件仓库配置：
<pluginRepositories> <pluginRepository> <id>publicid> <name>aliyun nexusname> <url>https://maven.aliyun.com/repository/public/url> <releases> <enabled>trueenabled> releases> <snapshots> <enabled>falseenabled> snapshots> pluginRepository> pluginRepositories>- 1

运行Maven的时候，Maven所需要的任何构件都是直接从本地仓库获取的。如果本地仓库没有，它会首先尝试从远程仓库下载构件至本地仓库，然后再使用本地仓库的构件
当我们运行install的时候，Maven实际上是将项目生成的构件安装到了本地仓库，即只有install了之后，其它项目才能使用此项目生成的构件packaging的配置：
pom：父类型都为pom类型, 在maven install时不会生成jar/war压缩包
<packaging>pompackaging>- 1
jar：内部调用或者是作服务使用,是默认的打包方式，
这种打包方式意味着在maven build时会将这个项目中的所有java文件都进行编译形成.class文件，且按照原来的java文件层级结构放置，最终压缩为一个jar文件<packaging>jarpackaging>- 1
war：打包项目，用于在容器（Tomcat、Jetty等）上部署
war包与jar包非常相似，同样是编译后的.class文件按层级结构形成文件树后打包形成的压缩包。不同的是，它会将项目中依赖的所有jar包都放在WEB-INF/lib这个文件夹下
war包非常适合部署时使用，不再需要下载其他的依赖包，能够使用户拿到war包直接使用，因此它经常使用于微服务项目群中的入口项目的pom配置中<packaging>warpackaging>- 1
build配置
指定install打包的包名
<build> <finalName>${project.artifactId}finalName> build> #默认的build <build> <defaultGoal>installdefaultGoal> <directory>${basedir}/targetdirectory> <finalName>${artifactId}-${version}finalName> <filters> <filter>filters/filter1.propertiesfilter> filters> ... build>- 1

全局配置（project build）
针对整个项目的所有情况都有效
配置（profile build）
针对不同的profile配置
参考： https://blog.csdn.net/zmemorys/article/details/105406053openfeign调用配置pom
在A微服务中采用feign调用，一个服务提供当前服务使用的接口和提供给外部使用的接口，此时， 创建两个模块，一个模块给自身提供服务接口，一个模块提供外部使用的接口（这个模块有DTO的定义，有DTO的定义就需要swagger的配置）所以该模块中依赖swagger构件,为了减少重复代码自身服务的模块需要依赖外部模块的构件，使用它的DTO和swagger依赖构件。
当外部B服务调用前者A服务的openfeign时，为了不需要重复写feign调用,需要依赖前者的A服务构件，这样的结构设计可以最大程度的简化代码避免冗余代码出现，也可以很好的管理服务间的调用，服务的提供方和服务的调用方，内部服务和外部服务很好的隔离组织在一起啦！
qar-flow-server内部服务的pom配置：
依赖提供外部服务的qar-flow-client构件和调用三方服务的qar-admin-client构件，client构件中依赖swagger和tools工具构件；<dependency> <groupId>io.qargroupId> <artifactId>qar-flow-clientartifactId> <version>${revision}version> dependency> <dependency> <groupId>io.qargroupId> <artifactId>qar-admin-clientartifactId> <version>${revision}version> dependency> <dependency> <groupId>io.qargroupId> <artifactId>qar-commons-logartifactId> dependency> <dependency> <groupId>io.qargroupId> <artifactId>qar-commons-mybatisartifactId> dependency>- 1

provided配置：
<scope>providedscope>- 1
使用provided标签的好处是可以减小最终打包的项目的大小，避免将不必要的库打包进去。同时，也方便服务器在运行时提供具体的库。
在install打包的qar-commons-dynamic-datasource的jar中，没有qar-commons-mybatis，但编译运行不受影响，如果有外部项目使用qar-commons-dynamic-datasource构件，就需要单独引入qar-commons-mybatis依赖构件；
好处：既方便依赖包的使用，也防止重复打包，减少代码冗余，减轻服务器的磁盘占用<artifactId>qar-commons-dynamic-datasourceartifactId> <packaging>jarpackaging> <dependencies> <dependency> <groupId>io.qargroupId> <artifactId>qar-commons-mybatisartifactId> <scope>providedscope> dependency> dependencies> <build> <finalName>${project.artifactId}finalName> build>- 1
