maven创建多模块web项目

实现步骤

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。

 
配置模块

生成各个模块
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=uppower.trade -DartifactId=trade-core
#client 模块创建
mvn archetype:create -DgroupId=uppower.trade -DartifactId=trade-client
#server 模块创建
mvn archetype:create -DgroupId=uppower.trade -DartifactId=trade-server -DpackageName=uppower.trade -DarchetypeArtifactId=maven-archetype-webapp

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>
  <parent>
  <groupId>uppower</groupId>
  <artifactId>parent</artifactId>
  <version>1.0.1</version>
 </parent>
  <groupId>uppower.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>
</project>

 
这里需要注意的是modules 节点，配置了上一步生成的四个模块。这样就组织起了其依赖关系。
生成好各个模块之后在tradework 根目录下会生成三个目录，每个目录下都会有一个 pom.xml 的配置文件，将这些配置文件打开。添加 parent 节点，client模块内容如下：

<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>uppower.trade</groupId>
  <artifactId>trade-parent</artifactId>
  <version>1.0-SNAPSHOT</version>
 </parent>
  <groupId>uppower.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> 

 
同理，针对core模块：

<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>uppower.trade</groupId>
  <artifactId>trade-parent</artifactId>
  <version>1.0-SNAPSHOT</version>
 </parent>
  <groupId>uppower.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>uppower.trade</groupId>
    <artifactId>trade-client</artifactId>
     <version>1.0-SNAPSHOT</version>
    </dependency>
  </dependencies>
</project> 

 
同理，针对server模块，其中值得注意的是，server模块是打包为war包：

<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>uppower.trade</groupId>
  <artifactId>trade-parent</artifactId>
  <version>1.0-SNAPSHOT</version>
 </parent>
  <groupId>uppower.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>
</dependencies>
 </project>

 
配置依赖
进入tradework 根目录，在 pom.xml 文件中加入 dependencies 节点，加入如下内容： 

<dependencyManagement>
   <dependencies>
     <dependency>
       <groupId>junit</groupId>
       <artifactId>junit</artifactId>
       <version>4.7</version>
       <scope>test</scope>
     </dependency>
     <dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring</artifactId>
   <version>2.0.7</version>
  </dependency>
  <dependency>
   <groupId>org.apache.ibatis</groupId>
   <artifactId>ibatis-sqlmap</artifactId>
   <version>2.3.0</version>
  </dependency>
  <dependency>
   <groupId>com.ibatis</groupId>
   <artifactId>ibatis-dao</artifactId>
   <version>2.1.0.565</version>
  </dependency>
  <dependency>
   <groupId>commons-dbcp</groupId>
   <artifactId>commons-dbcp</artifactId>
   <version>1.2.2</version>
  </dependency>
  
  <dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>5.1.12</version>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
  <version>2.5</version>
</dependency>
<dependency>
  <groupId>apache-log4j</groupId>
  <artifactId>log4j</artifactId>
  <version>1.2.15</version>
</dependency>
   </dependencies>
  </dependencyManagement>

  
进入tradework 根目录下，trade-server目录，在 pom.xml 文件中加入 dependencies 节点，内容如下：

<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>apache-log4j</groupId>
  <artifactId>log4j</artifactId>
</dependency>
<dependency>
  <groupId>javax.servlet</groupId>
  <artifactId>servlet-api</artifactId>
 
</dependency>
    <dependency>
    	<groupId>uppower.trade</groupId>
  		<artifactId>trade-client</artifactId>
    	<version>1.0-SNAPSHOT</version>
    </dependency>
    <dependency>
    	<groupId>uppower.trade</groupId>
  		<artifactId>trade-core</artifactId>
    	<version>1.0-SNAPSHOT</version>
    </dependency>
  </dependencies>
  <build>
    <finalName>trade-server</finalName>
  </build>

 

修改配置完成之后，在tradework目录下，执行：
mvn eclipse:eclipse
生成 Eclipse 项目文件及包引用定义，注意，需确保定义Classpath Variables: M2_REPO，指向本地maven类库目录。

打开Eclipse ，导入工程即可。
