Maven使用说明及规范

此文档主要说明Maven的基础使用方式,以及在使用过程过程中需要遵守哪些默认的准则。

我们工作中会经常写maven的配置,但是很多maven使用细节你可能并不知道,但你掌握后使用maven会更加上手。

MAVEN是什么?

Apache Maven是一个软件项目管理工具。基于项目对象模型(POM)的概念,Maven可以通过一小段描述信息来管理项目的构建,报告和文档。

Maven的核心是一个插件执行框架, 所有工作都是通过插件完成的。

最熟悉的插件如我们比较常用的:

clean

compiler

install

deploy

除了这些默认流程的插件,我们针对Maven的工作机制也制作了自己的插件,如 授权系统抽取api.json文件的插件,如通过erm对象描述文件生成Entity实体的插件等。

基本使用

基础信息

定义pom模型的基本信息

使用Maven构建的项目,首先需要在pom.xml文件中写明基本信息,如:

?
1
2
3
4
<groupId>com.yudianbank.project</groupId> //组织ID
    <artifactId>salesAppParent</artifactId>//工程名称
    <packaging>pom</packaging>//打包方式,如:jar、war、pom、rar等
    <version>1.0-RELEASES</version> //版本号

由groupId、artifactId、version三个元素定位唯一的jar信息,常说的发个Maven坐标也就是这三个元素

modules 节点,聚合子模块

在多模块的项目中使用,用来定义子模块,一般多模块项目中,父模块的packaging都定义为pom

?
1
2
3
4
<modules>
        <module>api</module>
        <module>producer</module>
    </modules>

parent节点,继承其他pom模型的属性

如:在spring boot项目中,会有如下parent节点,用来继承spring boot已经定义好的pom

?
1
2
3
4
5
6
<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.7.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

properties 节点,定义属性信息

这个节点一般用于定义一些属性,用来作为插件的默认值。在这里定义的属性可以贯穿Maven build的整个生命周期,Maven属性是值占位符,可以在pom中通过${XXX}符号来使用

?

<properties>
        <spring-cloud.version>Dalston.SR3</spring-cloud.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <compiler.version>1.8</compiler.version>
        <powermock.version>1.6.4</powermock.version>
        <checkstyle.version>6.18</checkstyle.version>
    </properties>

除了如上手动定义的一些属性,我们还可以通过如下的方式,访问到其他的一些变量,如:

  • env.X : 使用“env.”对变量进行前缀。将返回shell的环境变量。例如,$ {env.PATH}包含PATH环境变量。 注意:虽然环境变量本身在Windows上不区分大小写,但属性的查找区分大小写。换句话说,当Windows shell为%PATH%和%Path%返回相同的值时,Maven会区分$ {env.PATH}和$ {env.Path}。从Maven 2.1.0开始,为了可靠性,环境变量的名称被归一化为所有大写。
  • project.x : POM中的标记路径将包含相应元素的值。例如:<project> <version> 1.0 </ version> </ project>可通过$ {project.version}访问。
  • settings.x : Mavne Home路径的settings.xml将包含相应的元素的值。例如:<settings> <offline> false </ offline> </ settings>可通过$ {settings.offline}访问。
  • Java系统属性 : 通过java.lang.System.getProperties()访问的所有属性都可用作POM属性,例如${java.home}。

dependencies 节点,定义项目依赖

?

<dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
            </dependency>
        </dependencies>

除了基本的groupId、artifactId、version坐标属性外,dependency节点中还包括如下的常用属性设置

  • type : 依赖的类型,默认是jar
  • classifier : 分类器,额外的jar坐标标记,用来依赖那些从同一个POM中打出的不同的jar包。
  • scope : 依赖的jar的作用范围,可选(compile,runtime,test,system,provided)
  • compile : 这是默认范围。所有类路径中都提供了编译依赖项。此外,这些依赖项将传播到依赖项目
  • runtime : 这很像compile,但表示您希望JDK或容器在运行时提供它。它仅在编译和测试类路径中可用,并且不可传递。
  • test : 此范围表示正常使用应用程序不需要依赖项,并且仅适用于测试编译和执行阶段。它不是传递性的。
  • provided :这很像compile,但表示您希望JDK或容器在运行时提供它。它仅在编译和测试类路径中可用,并且不可传递。
  • system :此范围与provided的类似,只是您必须提供明确包含它的JAR,声明后不会在存储库中查找
  • Systempath:当scope为system生效,用于定义本地依赖的路径
  • optional :是否启用依赖传递,默认false需要依赖传递。如A依赖B,B依赖C,默认情况下A中会有C的依赖,如果在依赖B时设置optional为true,则A中不会有C的依赖
  • exclusions :排除依赖传递

dependencies -> exclusions 节点,排除依赖传递

有时候为了解决项目依赖冲突,需要排除依赖的jar包通过Maven依赖传递特性引用的其他jar,如:

?
1
2
3
4
5
6
7
8
9
10
11
<dependency>
            <groupId>com.yudianbank.public</groupId>
            <artifactId>pdf</artifactId>
            <version>1.1-RELEASES</version>
            <exclusions>
                <exclusion>
                    <groupId>commons-pool</groupId>
                    <artifactId>commons-pool</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

关于Maven依赖传递特性,当出现多个jar依赖相同的不同版本jar时,遵循两个原则来引用:

  • 最短路径原则:如A->B->C-D1 , A->B1->D2 , 那么最终项目A依赖的D的版本是D2。
  • 最先定义原则: 如A->B->D1 , A->C->D2 , 那么最终项目A雨来的D的版本是D1.

dependencyManagement 节点,声明依赖项

dependencyManagement用来管理声明依赖项,最常见于spring boot项目中,在依赖节点只需要写groupId、artifactId就可以定位一个jar坐标,是因为spring boot的父pom中使用dependencyManagement声明了常用的依赖项,如:

?
1
2
3
4
5
6
7
8
9
10
11
<dependencyManagement>
  <dependencies>
   <!-- Spring Boot -->
   <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot</artifactId>
    <version>1.5.7.RELEASE</version>
   </dependency>
   .......
  </dependencies>
   </dependencyManagement>

使用dependencyManagement管理的依赖只是声明了,如果没有显示的定义在< dependencies >节点中是不生效的

profiles -> profile 节点,定义不同环境的构建属性

在软件项目迭代中,通常会有开发、测试、生产等不同的运行环境。很多时候不同的环境需要不同的依赖属性,诸如此场景,都可以使用profiles来定义不同环境下的变量,如:

            </activation>
            <properties>
                <!--销售平台 api版本-->
                <sales.api.version>1.0-SNAPSHOT</sales.api.version>
                <!--本地日志存储地址-->
                <logging.path>${basedir}/target/logs</logging.path>
            </properties>
        </profile>
        <profile>
            <id>uat</id>
            <properties>
                <sales.api.version>1.0-SNAPSHOT</sales.api.version>
                <logging.path>/data/logs/${appName}</logging.path>
            </properties>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <sales.api.version>1.0-RELEASES</sales.api.version>
                <logging.path>/data/logs/${appName}</logging.path>
            </properties>
        </profile>  
    </profiles>

repositories、pluginRepositories 节点,定义依赖和插件的仓库地址

这里可以定义jar拉取的仓库地址,除了Apache中央仓库外,还有很多其他的开源仓库,如spring的,

      <releases>
        <updatePolicy>never</updatePolicy>
      </releases>
    </pluginRepository>
  </pluginRepositories>

构建信息

build 节点,设置输入输出路径

为什么在使用Maven构建的项目中,项目编译后会在pom所在目录下生成target目录?是因为在build构建节点中有如下的默认的配置。

当然,如果你显示配置了如下的属性,就可以指定编译后文件的输出目录

?
1
2
3
4
5
6
7
8
<build>
    <sourceDirectory>${basedir}/src/main/java</sourceDirectory>
    <scriptSourceDirectory>${basedir}/src/main/scripts</scriptSourceDirectory>
    <testSourceDirectory>${basedir}/src/test/java</testSourceDirectory>
    <outputDirectory>${basedir}/target/classes</outputDirectory>
    <testOutputDirectory>${basedir}/target/test-classes</testOutputDirectory>
    ...
  </build>

build -> resources,定义项目资源

resources用来定义项目的资源路径,默认的路径为${basedir}/src/main/resources,在spring boot环境中,继承了spring boot的父pom属性,它的resources定义如下:

?

10
11
12
13

19
<resources>
   <resource>
    <directory>${basedir}/src/main/resources</directory>
    <filtering>true</filtering>
    <includes>
     <include>**/application*.yml</include>
     <include>**/application*.yaml</include>
     <include>**/application*.properties</include>
    </includes>
   </resource>
   <resource>
    <directory>${basedir}/src/main/resources</directory>
    <excludes>
     <exclude>**/application*.yml</exclude>
     <exclude>**/application*.yaml</exclude>
     <exclude>**/application*.properties</exclude>
    </excludes>
   </resource>
  </resources>

可以看到,spring boot中只定义了三种文件类型的资源,而且通配application开头的文件。

当项目中有其他的文件类型或不是application开头时,Maven就会过滤掉。

而且在spring boot中定义了属性占位符为@符号,所以在资源文件中使用${}时并不会生效。

为了解决这个问题,可以自己在pom中定义resources属性覆盖父pom的行为:如,

?

<resources>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>

build -> plugins -> plugin,定义构建插件

plugin这个节点主要用来定义构建的插件,包括自定义和已经发布到中央仓库的。如spring boot环境想构建可执行的jar需要添加spring-boot-maven-plugin插件。

distributionManagement 节点,配置deploy的仓库地址

当我们自己搭建了私服,想要将jar包编译后上传到私服时,需要在这个节点配置仓库的地址,如:

?

        </repository>
        <snapshotRepository>
            <id>repo</id>
            <name>User Project SNAPSHOTS</name>
            <url>http://192.168.1.204:8081/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

项目信息

根节点下的name、description、url等节点

根节点下的name、description、url等节点用来描述项目的基本信息,如:

?
1
2
3
<name>sales</name>
      <description>这是一个销售系统</description>
      <url>http://www.kailing.pub</url>

Licenses节点,描述许可证信息

<licenses>
  <license>
    <name>Apache License, Version 2.0</name>

    <distribution>repo</distribution>
    <comments>A business-friendly OSS license</comments>
  </license>

Organization节点,描述组织信息

?

<organization>
    <name>keking</name>
    <url>http://www.keking.cn</url>
  </organization>

省略....

遵守的准则规范

MAVEN坐标VERSION属性设置

一般建议在开发和测试环境中的jar,打成SNAPSHOT的,生产环境的版本打成RELEASES的,这个可以通过上面的profiles节点来控制,他们的区别如下:

  • SNAPSHOT :当版本号带'-SNAPSHOT'后缀时,既定义发布的jar为快照版本,应用在依赖时,总是会拉取最新的快照版本。
  • RELEASES :当版本号带'-RELEASES'后缀时,既定义发布的jar为发行版,应用依赖时,首次会从远程仓库拉取,当本地仓库已有时,就不会从远程仓库拉最新的依赖了。RELEASES版本的每次更新必须指定版本号。

开发中的API模块,需要DEPLOY

应用有些模块需要提供给别人依赖,比如api模块、common模块等。在开发时,每次接口有变动时,记得mvn deploy下,把jar上传到私服。

依赖的JAR的版本使用属性控制

建议依赖别的jar时,不要写死jar的版本,通过properties节点定义的属性来控制,那么当你pom被别人依赖时,上层pom可以通过定义属性值覆盖父pom中属性来控制依赖的版本

多模块项目时,模块命名规范

在多模块时,子模块的命名建议使用父模块作为前缀,如sales系统,api模块为sales-api,app模块为sales-app
