maven创建多模块web项目

基本思路为先建父工程，再建子工程，其中trade-server为web项目；建文件夹，运行三条建子工程的命令，在新建的文件夹中新建pom.xml，填充内容。再修改三个子工程的pom.xml。子工程要指向父工程，需要的依赖包都写进pom.xml中。

一、创建项目目录。进入“工作空间”目录，创建名为tradework 的文件夹，切换至控制台，进入该文件夹。

二、生成各模块

该步骤会依次生成项目的各个模块，但是生成的模块并没有 创建依赖，只是最简单的并且符合maven 要求的项目结构的模块，关于什么是 maven 的标准项目结构，可以参考 maven 官方文档，或者《 maven 权威指南》。
#core 模块创建
mvn archetype:create -DgroupId=com.taobao.trade -DartifactId=trade-core
#client 模块创建
mvn archetype:create -DgroupId=com.taobao.trade -DartifactId=trade-client
#server 模块创建
mvn archetype:create -DgroupId=com.taobao.trade -DartifactId=trade-server -DpackageName=com.taobao.trade -DarchetypeArtifactId=maven-archetype-webapp

三、配置项目模块

在tradework 根目录下新建一个 pom.xml 配置文件，加入如下内容：

<?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.taobao.trade</groupId>
<artifactId>trade-parent</artifactId>
<packaging>pom</packaging>
<version>1.0-SNAPSHOT</version>
<name>trade-parent</name>
<url>http://maven.apache.org</url>
<modules>
<module>trade-client</module>
<module>trade-core</module>
<module>trade-server</module>
</modules>

<dependencyManagement>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.7</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework</groupId>

</dependency>
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>

</dependency>

<dependency>

<dependency>
<groupId>apache-log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.15</version>
</dependency>
</dependencies>
</dependencyManagement>

</project>
四、server模块，该模块为web模块，该模块的pom.xml内容为下：

<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>
<parent>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-server</artifactId>
<packaging>war</packaging>
<version>1.0-SNAPSHOT</version>
<name>trade-server Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring</artifactId>

</dependency>
<dependency>
<groupId>org.apache.ibatis</groupId>
<artifactId>ibatis-sqlmap</artifactId>

</dependency>
<dependency>
<groupId>com.ibatis</groupId>
<artifactId>ibatis-dao</artifactId>

</dependency>
<dependency>
<groupId>commons-dbcp</groupId>
<artifactId>commons-dbcp</artifactId>
</dependency>

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>

</dependency>
<dependency>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-client</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-core</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
<build>
<finalName>trade-server</finalName>
</build>

</project>

五、core模块，其pom.xml为：

<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>

<parent>

<groupId>com.taobao.trade</groupId>

<artifactId>trade-parent</artifactId>

<version>1.0-SNAPSHOT</version>

</parent>

<groupId>com.taobao.trade</groupId>

<artifactId>trade-core</artifactId>

<packaging>jar</packaging>

<version>1.0-SNAPSHOT</version>

<name>trade-core</name>

<url>http://maven.apache.org</url>

<dependencies>

<dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

</dependency>

<dependency>

<groupId>com.taobao.trade</groupId>

<artifactId>trade-client</artifactId>

<version>1.0-SNAPSHOT</version>

</dependency>

</dependencies>

</project>

六、client模块，pom.xml为：

<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>
<parent>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<groupId>com.taobao.trade</groupId>
<artifactId>trade-client</artifactId>
<packaging>jar</packaging>
<version>1.0-SNAPSHOT</version>
<name>trade-client</name>
<url>http://maven.apache.org</url>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
</dependency>
</dependencies>
</project>

七、运行mvn eclipse:eclipse，然后导入eclipse中，将server模块转换为web工程的方法与之前相同
