示例一

Maven多模块项目

  Maven多模块项目,适用于一些比较大的项目,通过合理的模块拆分,实现代码的复用,便于维护和管理。尤其是一些开源框架,也是采用多模块的方式,提供插件集成,用户可以根据需要配置指定的模块。

  项目结构如下:

      test-hd-parent   (父级)
             ---pom.xml
             ---test-hd-api          (第三方接口层)
                    ----pom.xml    
           ---test-hd-foundation     (基础工具层)
                    ----pom.xml
             ---test-hd-resource     (资源层) 
                    ----pom.xml
             ---test-hd-service       (逻辑业务层)
                    ----pom.xml
           ---test-hd-modules     (web层)
                    ----pom.xml
                ---test-hd-www         (web模块1)
                            ----pom.xml
                ---test-hd-admin        (web模块2)
                            ----pom.xml  

 

创建一个父maven工程

  •   新建一个maven项目,选择存储位置,并选择创建一个简单的maven工程

    

  •   输入Group Id、Artifact Id、Packaging,packaging选择pom包

    

  •   生成父工程,pom.xml如下

    

  •   删除工程中的src 目录

    

创建子模块

  •   右击父工程名---》New---》Project,然后选择新建一个maven module工程

    

  •   设置子工程名以及父工程,再设置快速创建模式

    

  •   得到子工程(test-hd-api,第三方接口层),设置编译的jdk

    

  •   同理设置,子模块:test-hd-foundation(基础工具层)、test-hd-resource(资源层) 、test-hd-service(逻辑业务层)
  •   新建test-hd-modules (web层),选择创建一个a simple project,输入Group Id、Artifact Id、Packaging,packaging选择pom包

        

创建web子模块

  •   web子模块在建在test-hd-modules (web层)里面,右击test-hd-modules 工程名---》New---》Project,然后选择新建一个maven module工程,设置子工程名以及父工程,选择新建web项目

    

    

 

配置个模块的依赖

  •   在parent项目pom.xml中建立依赖管理(dependencyManagement)

示例二

在平时的Javaweb项目开发中为了便于后期的维护,我们一般会进行分层开发,最常见的就是分为domain(域模型层)、dao(数据库访问层)、service(业务逻辑层)、web(表现层),这样分层之后,各个层之间的职责会比较明确,后期维护起来也相对比较容易,今天我们就是使用Maven来构建以上的各个层。

  项目结构如下:

  system-parent         |----pom.xml         |----system-domain                 |----pom.xml         |----system-dao                 |----pom.xml         |----system-service                 |----pom.xml         |----system-web                 |----pom.xml

一、创建system-parent项目

  创建system-parent,用来给各个子模块继承。

  进入命令行,输入以下命令:

mvn archetype:create -DgroupId=me.gacl -DartifactId=system-parent -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

  如下图所示:

  

  命令执行完成之后可以看到在当前目录(C:\Documents and Settings\Administrator)生成了system-parent目录,里面有一个src目录和一个pom.xml文件,如下图所示:

  

  将src文件夹删除,然后修改pom.xml文件,将<packaging>jar</packaging>修改为<packaging>pom</packaging>,pom表示它是一个被继承的模块,修改后的内容如下:

复制代码
 1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 2   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
 3   <modelVersion>4.0.0</modelVersion>
 4 
 5   <groupId>me.gacl</groupId>
 6   <artifactId>system-parent</artifactId>
 7   <version>1.0-SNAPSHOT</version>
 8   <packaging>pom</packaging>
 9 
10   <name>system-parent</name>
11   <url>http://maven.apache.org</url>
12 
13   <properties>
14     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
15   </properties>
16 
17   <dependencies>
18     <dependency>
19       <groupId>junit</groupId>
20       <artifactId>junit</artifactId>
21       <version>3.8.1</version>
22       <scope>test</scope>
23     </dependency>
24   </dependencies>
25 </project>
复制代码

二、创建sytem-domain模块

  在命令行进入创建好的system-parent目录,然后执行下列命令:

mvn archetype:create -DgroupId=me.gacl -DartifactId=system-domain -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

  如下图所示:

  

  命令执行完成之后可以看到在system-parent目录中生成了system-domain,里面包含src目录和pom.xml文件。如下图所示:

  

  

  同时,在system-parent目录中的pom.xml文件自动添加了如下内容:

<modules>
    <module>system-domain</module>
</modules>

  这时,system-parent的pom.xml文件如下:

复制代码
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project 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/maven-4.0.0.xsd">
 3   <modelVersion>4.0.0</modelVersion>
 4 
 5   <groupId>me.gacl</groupId>
 6   <artifactId>system-parent</artifactId>
 7   <version>1.0-SNAPSHOT</version>
 8   <packaging>pom</packaging>
 9 
10   <name>system-parent</name>
11   <url>http://maven.apache.org</url>
12 
13   <properties>
14     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
15   </properties>
16 
17   <dependencies>
18     <dependency>
19       <groupId>junit</groupId>
20       <artifactId>junit</artifactId>
21       <version>3.8.1</version>
22       <scope>test</scope>
23     </dependency>
24   </dependencies>
25   <modules>
26     <module>system-domain</module>
27   </modules>
28 </project>
复制代码

  修改system-domain目录中的pom.xml文件,把<groupId>me.gacl</groupId><version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>,因为groupId和version会继承system-parent中的groupId和version,packaging设置打包方式为jar

  修改过后的pom.xml文件如下:

复制代码
 1 <?xml version="1.0"?>
 2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4   <modelVersion>4.0.0</modelVersion>
 5   <parent>
 6     <groupId>me.gacl</groupId>
 7     <artifactId>system-parent</artifactId>
 8     <version>1.0-SNAPSHOT</version>
 9   </parent>
10   
11   <artifactId>system-domain</artifactId>
12   <packaging>jar</packaging>
13   
14   <name>system-domain</name>
15   <url>http://maven.apache.org</url>
16 </project>
复制代码

三、创建sytem-dao模块

  在命令行进入创建好的system-parent目录,然后执行下列命令:

mvn archetype:create -DgroupId=me.gacl -DartifactId=system-dao -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

  如下图所示:

  

  命令执行完成之后可以看到在system-parent目录中生成了system-dao,里面包含src目录和pom.xml文件。如下图所示:

  

  同时,在system-parent目录中的pom.xml文件自动变成如下内容:

复制代码
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project 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/maven-4.0.0.xsd">
 3   <modelVersion>4.0.0</modelVersion>
 4 
 5   <groupId>me.gacl</groupId>
 6   <artifactId>system-parent</artifactId>
 7   <version>1.0-SNAPSHOT</version>
 8   <packaging>pom</packaging>
 9 
10   <name>system-parent</name>
11   <url>http://maven.apache.org</url>
12 
13   <properties>
14     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
15   </properties>
16 
17   <dependencies>
18     <dependency>
19       <groupId>junit</groupId>
20       <artifactId>junit</artifactId>
21       <version>3.8.1</version>
22       <scope>test</scope>
23     </dependency>
24   </dependencies>
25   <modules>
26     <module>system-domain</module>
27     <module>system-dao</module>
28   </modules>
29 </project>
复制代码

  修改system-dao目录中的pom.xml文件,,把<groupId>me.gacl</groupId><version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>因为groupId和version会继承system-parent中的groupId和version,packaging设置打包方式为jar,同时添加对system-domain模块的依赖,修改后的内容如下:

复制代码
 1 <?xml version="1.0"?>
 2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4   <modelVersion>4.0.0</modelVersion>
 5   <parent>
 6     <groupId>me.gacl</groupId>
 7     <artifactId>system-parent</artifactId>
 8     <version>1.0-SNAPSHOT</version>
 9   </parent>
10 
11   <artifactId>system-dao</artifactId>
12   <packaging>jar</packaging>
13 
14   <name>system-dao</name>
15   <url>http://maven.apache.org</url>
16   <properties>
17     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
18   </properties>
19   <dependencies>
20     <!--system-dao需要使用到system-domain中的类,所以需要添加对system-domain模块的依赖-->
21      <dependency>
22       <groupId>me.gacl</groupId>
23       <artifactId>system-domain</artifactId>
24       <version>${project.version}</version>
25     </dependency>
26   </dependencies>
27 </project>
复制代码

四、创建system-service模块

  在命令行进入创建好的system-parent目录,然后执行下列命令:

mvn archetype:create -DgroupId=me.gacl -DartifactId=system-service -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

  如下图所示:

  

  命令执行完成之后可以看到在system-parent目录中生成了system-service,里面包含src目录和pom.xml文件。如下图所示:

  

  同时,在system-parent目录中的pom.xml文件自动变成如下内容:

复制代码
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project 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/maven-4.0.0.xsd">
 3   <modelVersion>4.0.0</modelVersion>
 4 
 5   <groupId>me.gacl</groupId>
 6   <artifactId>system-parent</artifactId>
 7   <version>1.0-SNAPSHOT</version>
 8   <packaging>pom</packaging>
 9 
10   <name>system-parent</name>
11   <url>http://maven.apache.org</url>
12 
13   <properties>
14     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
15   </properties>
16 
17   <dependencies>
18     <dependency>
19       <groupId>junit</groupId>
20       <artifactId>junit</artifactId>
21       <version>3.8.1</version>
22       <scope>test</scope>
23     </dependency>
24   </dependencies>
25   <modules>
26     <module>system-domain</module>
27     <module>system-dao</module>
28     <module>system-service</module>
29   </modules>
30 </project>
复制代码

  修改system-service目录中的pom.xml文件,,把<groupId>me.gacl</groupId><version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>因为groupId和version会继承system-parent中的groupId和version,packaging设置打包方式为jar,同时添加对system-dao模块的依赖system-service依赖system-dao和system-domain,但是我们只需添加system-dao的依赖即可,因为system-dao已经依赖了system-domain。修改后的内容如下:

复制代码
 1 <?xml version="1.0"?>
 2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4   <modelVersion>4.0.0</modelVersion>
 5   <parent>
 6     <groupId>me.gacl</groupId>
 7     <artifactId>system-parent</artifactId>
 8     <version>1.0-SNAPSHOT</version>
 9   </parent>
10 
11   <artifactId>system-service</artifactId>
12   <packaging>jar</packaging>
13   
14   <name>system-service</name>
15   <url>http://maven.apache.org</url>
16   <properties>
17     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
18   </properties>
19   <dependencies>
20     <!--
21     system-service依赖system-dao和system-domain,
22     但是我们只需添加system-dao的依赖即可,因为system-dao已经依赖了system-domain
23     -->
24      <dependency>
25       <groupId>me.gacl</groupId>
26       <artifactId>system-dao</artifactId>
27       <version>${project.version}</version>
28     </dependency>
29   </dependencies>
30 </project>
复制代码

五、创建system-web模块

  在命令行进入创建好的system-parent目录,然后执行下列命令:

mvn archetype:create -DgroupId=me.gacl -DartifactId=system-web -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false

  如下图所示:

  

  命令执行完成之后可以看到在system-parent目录中生成了system-web,里面包含src目录和pom.xml文件。如下图所示:

  

  在\system-web\src\main\webapp目录中还生成了一个简单的index.jsp,如下图所示:

  

  里面的内容为

<html>
<body>
<h2>Hello World!</h2>
</body>
</html>

  system-web\src\main\webapp\WEB-INF目录中生成了web.xml

  

  同时,在system-parent目录中的pom.xml文件自动变成如下内容:

复制代码
 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <project 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/maven-4.0.0.xsd">
 3   <modelVersion>4.0.0</modelVersion>
 4 
 5   <groupId>me.gacl</groupId>
 6   <artifactId>system-parent</artifactId>
 7   <version>1.0-SNAPSHOT</version>
 8   <packaging>pom</packaging>
 9 
10   <name>system-parent</name>
11   <url>http://maven.apache.org</url>
12 
13   <properties>
14     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
15   </properties>
16 
17   <dependencies>
18     <dependency>
19       <groupId>junit</groupId>
20       <artifactId>junit</artifactId>
21       <version>3.8.1</version>
22       <scope>test</scope>
23     </dependency>
24   </dependencies>
25   <modules>
26     <module>system-domain</module>
27     <module>system-dao</module>
28     <module>system-service</module>
29     <module>system-web</module>
30   </modules>
31 </project>
复制代码

  修改system-web目录中的pom.xml文件,,把<groupId>me.gacl</groupId><version>1.0-SNAPSHOT</version>去掉,因为groupId和version会继承system-parent中的groupId和version,同时添加对system-service模块的依赖修改后的内容如下:

复制代码
 1 <?xml version="1.0"?>
 2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4   <modelVersion>4.0.0</modelVersion>
 5   <parent>
 6     <groupId>me.gacl</groupId>
 7     <artifactId>system-parent</artifactId>
 8     <version>1.0-SNAPSHOT</version>
 9   </parent>
10 
11   <artifactId>system-web</artifactId>
12   <packaging>war</packaging>
13   
14   <name>system-web Maven Webapp</name>
15   <url>http://maven.apache.org</url>
16   <dependencies>
17     <!--
18     system-web依赖system-service
19     -->
20      <dependency>
21       <groupId>me.gacl</groupId>
22       <artifactId>system-service</artifactId>
23       <version>${project.version}</version>
24     </dependency>
25   </dependencies>
26   <build>
27     <finalName>system-web</finalName>
28   </build>
29 </project>
复制代码

   注意,web项目的打包方式是war

六、编译运行项目

  经过上面的五个步骤,相关的模块全部创建完成,怎么运行起来呢。由于最终运行的是system-web模块,所以我们对该模块添加jetty支持,方便测试运行。修改system-web项目的pom.xml如下:

复制代码
 1 <?xml version="1.0"?>
 2 <project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
 3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4   <modelVersion>4.0.0</modelVersion>
 5   <parent>
 6     <groupId>me.gacl</groupId>
 7     <artifactId>system-parent</artifactId>
 8     <version>1.0-SNAPSHOT</version>
 9   </parent>
10 
11   <artifactId>system-web</artifactId>
12   <packaging>war</packaging>
13   
14   <name>system-web Maven Webapp</name>
15   <url>http://maven.apache.org</url>
16   <dependencies>
17     <!--
18     system-web依赖system-service
19     -->
20      <dependency>
21       <groupId>me.gacl</groupId>
22       <artifactId>system-service</artifactId>
23       <version>${project.version}</version>
24     </dependency>
25   </dependencies>
26   <build>
27     <finalName>system-web</finalName>
28     <plugins>
29         <!--配置Jetty插件-->
30         <plugin>
31             <groupId>org.mortbay.jetty</groupId>
32             <artifactId>maven-jetty-plugin</artifactId>
33         </plugin>
34     </plugins>
35   </build>
36 </project>
复制代码

  在命令行进入system-parent目录,然后执行下列命令:

mvn clean install

  如下图所示:

  

  

  命令执行完后,在system-web目录下多出了target目录,里面有了system-web.war,如下图所示:

  

  命令行进入sytem-web目录,执行如下命令,启动jetty
