mvn cli 搭建项目架构

创建如图所示目录结构

在system-parent创建如下目录

├─system-dao

├─system-domain

├─system-service

└─system-web

创建system-parent

mvn archetype:generate -DgroupId=com.hbb0b0 -DartifactId=system-parent -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -DarchetypeCatalog=local

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<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/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.hbb0b0</groupId>
  <artifactId>system-parent</artifactId>
  <packaging>pom</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>system-parent</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
  <modules>
    <module>system-domain</module>
    <module>system-dao</module>
    <module>system-service</module>
    <module>system-web</module>
  </modules>
</project>

说明

• system-parent 只需要 pom文件
• 修改 jar 为 pom
• 其中 节点的内容是子项目创建后自己加上去的，不用手工加

创建子项目 system-domain

mvn archetype:generate -DgroupId=com.hbb0b0 -DartifactId=system-domain -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -DarchetypeCatalog=local

pom.xml

<?xml version="1.0"?>
<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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.hbb0b0</groupId>
    <artifactId>system-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <artifactId>system-domain</artifactId>
  <name>system-domain</name>
  <packaging>jar</packaging>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

说明

• 去掉子项目 ,去掉之后表示子项目的version,groupid 继承自 system-parent pom
• 添加 jar

创建子项目 system-do

mvn archetype:generate -DgroupId=com.hbb0b0 -DartifactId=system-dao -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -DarchetypeCatalog=local

pom.xml

<?xml version="1.0"?>
<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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.hbb0b0</groupId>
    <artifactId>system-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <artifactId>system-dao</artifactId>
  <packaging>jar</packaging>
  <name>system-dao</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
	<dependency>
      <groupId>com.hbb0b0</groupId>
      <artifactId>system-domain</artifactId>
      <version>${project.version}</version>
    </dependency>
  </dependencies>
</project>

说明

• 去掉子项目 ,去掉之后表示子项目的version,groupid 继承自 system-parent pom
• 添加 jar
• system-dao 依赖 system-domain ，所以dependency 添加 system-domain 依赖

创建子项目 system-service

mvn archetype:generate -DgroupId=com.hbb0b0 -DartifactId=system-service -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false -DarchetypeCatalog=local

pom.xml

<?xml version="1.0"?>
<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"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <parent>
    <groupId>com.hbb0b0</groupId>
    <artifactId>system-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
  </parent>
  <artifactId>system-service</artifactId>
  <name>system-service</name>
   <packaging>jar</packaging>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
	<dependency>
      <groupId>com.hbb0b0</groupId>
      <artifactId>system-dao</artifactId>
      <version>${project.version}</version>
    </dependency>

  </dependencies>
</project>

说明

• 去掉子项目 ,去掉之后表示子项目的version,groupid 继承自 system-parent pom
• 添加 jar
• service 直接依赖 system-dao ,system-dao依赖system-domain，dependency 添加直接依赖 system-dao ，不需要添加system-domain 的依赖

创建子项目 system-web

mvn archetype:generate -DgroupId=com.hbb0b0 -DartifactId=system-web -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false -DarchetypeCatalog=local

pom.xml

<?xml version="1.0"?>

  <artifactId>system-web</artifactId>
  <packaging>war</packaging>
  <name>system-web Maven Webapp</name>

	<dependency>
      <groupId>com.hbb0b0</groupId>
      <artifactId>system-service</artifactId>
      <version>${project.version}</version>
    </dependency>
  </dependencies>
  <build>
    <finalName>system-web</finalName>
	<pluginManagement>
        <!--配置Jetty-->
        <plugins>
           <plugin>
            <groupId>org.mortbay.jetty</groupId>
             <artifactId>maven-jetty-plugin</artifactId>
            </plugin>
         </plugins>
     </pluginManagement>
  </build>
</project>

说明

• 去掉子项目 ,去掉之后表示子项目的version,groupid 继承自 system-parent pom
• 添加 jar
• 添加 system-service 依赖
• 添加 jetty 插件 ，这样做的目的，让web项目直接在命令行运行
  
  --修改 jsp文件 添加项目目录结构

清理与编译

在 system-parent目录运行

mvn clean install

执行成功之后 可以看到以下输出
