①创建queen-parent工程

为了便于管理，我们新建一个文件夹管理我们新建的工程，点击图中小三角->Top Level Elements->Working Sets，如图：

然后，我们在工程左边空白区域右键 -> Java Working Set

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 3][Eclipse_Maven_ - 3]

点击 Finish，工程如下：

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 5][Eclipse_Maven_ - 5]

然后，我们开始创建queen-parent，New -> Other

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 7][Eclipse_Maven_ - 7]

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 9][Eclipse_Maven_ - 9]

点击 Next，注意Create a simple project(skip archetype selection) 打勾

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 11][Eclipse_Maven_ - 11]

点击 Next ，注意：打包方式为pom

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 13][Eclipse_Maven_ - 13]

点击Finish 完成，如图：

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 15][Eclipse_Maven_ - 15]

Pom文件如下：

<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.queen.parent</groupId> <artifactId>queen-parent</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>pom</packaging>  <properties> <junit.version>4.10</junit.version> <spring.version>4.1.3.RELEASE</spring.version> <mybatis.version>3.2.8</mybatis.version> <mybatis.spring.version>1.2.2</mybatis.spring.version> <mybatis.paginator.version>1.2.15</mybatis.paginator.version> <mysql.version>5.1.32</mysql.version> <slf4j.version>1.6.4</slf4j.version> <jackson.version>2.4.2</jackson.version> <druid.version>1.0.9</druid.version> <httpclient.version>4.3.5</httpclient.version> <jstl.version>1.2</jstl.version> <servlet-api.version>2.5</servlet-api.version> <jsp-api.version>2.0</jsp-api.version> <joda-time.version>2.5</joda-time.version> <commons-lang3.version>3.3.2</commons-lang3.version> <commons-io.version>1.3.2</commons-io.version> </properties> <dependencyManagement> <dependencies>  <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency>  <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency>  <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis.spring.version}</version> </dependency>  <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>3.7.5</version> </dependency> <dependency> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> <version>0.9.1</version> </dependency>  <dependency> <groupId>com.github.abel533</groupId> <artifactId>mapper</artifactId> <version>2.3.4</version> </dependency>  <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency>  <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>${jackson.version}</version> </dependency>  <dependency> <groupId>com.jolbox</groupId> <artifactId>bonecp-spring</artifactId> <version>0.8.0.RELEASE</version> </dependency>  <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>${httpclient.version}</version> </dependency>  <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servlet-api.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> <scope>provided</scope> </dependency>  <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> <version>${joda-time.version}</version> </dependency>  <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>${commons-lang3.version}</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> <version>${commons-io.version}</version> </dependency> </dependencies> </dependencyManagement> <build> <finalName>${project.artifactId}</finalName> <plugins>  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.7</version> <configuration> <encoding>UTF-8</encoding> </configuration> </plugin>  <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> <encoding>UTF-8</encoding> </configuration> </plugin> </plugins> <pluginManagement> <plugins>  <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> </plugin> </plugins> </pluginManagement> </build> </project>

②创建公用工程queen-common

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 17][Eclipse_Maven_ - 17]

点击 Next，注意Create a simple project(skip archetype selection) 打勾

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 19][Eclipse_Maven_ - 19]

点击 Next ，注意：打包方式为jar

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 21][Eclipse_Maven_ - 21]

创建成功：

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 23][Eclipse_Maven_ - 23]

Pom文件如下：

pom文件里面，queen-common继承queen-parent，保存。此时工程可能报错

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 25][Eclipse_Maven_ - 25]

那么，我们怎么处理呢？选中queen-common，右键->Maven->Update Maven Project

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 27][Eclipse_Maven_ - 27]

点击 OK，工程错误消失。

③创建queen-manage

前面步骤类似，就不再赘述了，注意下面打包方式为pom

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 29][Eclipse_Maven_ - 29]

点击 Finish完成

queen-manage也要继承queen-parent，pom文件如下：

然后，创建queen-manage-pojo，注意：我们是在queen-manage下面，新建子模块，我们选择的Maven Module类型

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 31][Eclipse_Maven_ - 31]

点击Next

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 33][Eclipse_Maven_ - 33]

再点击Next

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 35][Eclipse_Maven_ - 35]

紧接着我们依次创建queen-manage-mapper，queen-manage-service，queen-manage-controller工程，步骤跟queen-manage-pojo一样。

注意：在我们创建queen-manage-controller时，打包方式要选择war。

最终我们新建的所有工程如下：

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 37][Eclipse_Maven_ - 37]

④现在我们要整理一下子工程之间的依赖关系

queen-manage-controller-依赖-queen-manage-service-依赖-queen-manage-mapper-依赖-queen-manage-pojo

上面可知，我们的依赖关系如此。

那我们修改一下pom文件

在queen-manage-mapper的pom文件中加入queen-manage-pojo的坐标

<dependency> <groupId>com.queen.manage</groupId> <artifactId>queen-manage-pojo</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>

在queen-manage-service的pom文件中加入queen-manage-mapper的坐标

<dependency> <groupId>com.queen.manage</groupId> <artifactId>queen-manage-mapper</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>

在queen-manage-controller的pom文件中加入queen-manage-service的坐标

<dependency> <groupId>com.queen.manage</groupId> <artifactId>queen-manage-service</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>

⑤各个工程中导入依赖

在queen-manage-controller工程的pom文件完整依赖：

在queen-manage-service工程的pom文件完整依赖：

在queen-manage-mapper工程的pom文件完整依赖：

在queen-manage-pojo工程的pom文件完整依赖：

在queen-manage工程的pom文件完整依赖：

⑥运行工程

注意：运行之前，每个工程需要clean和install一下，当queen-manage聚合工程install的时候，可能报错，报web.xml找不到，这时候做如下操作，在queen-manage-controller的webapp目录下面新建一个WEB-INF文件夹，并在此文件夹下面新建一个web.xml文件，在webapp下面新建一个index.jsp文件。

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 39][Eclipse_Maven_ - 39]

web.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>queen-manage</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>

index.jsp文件如下：

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>index</title> </head> <body> Welcome：queen </body>

通过插件的方式运行工程

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 41][Eclipse_Maven_ - 41]

运行起来之后，我们访问一下服务http://localhost:8080/index.jsp

![Eclipse下Maven工程多模块继承和聚合创建(详解)的照片 - 43][Eclipse_Maven_ - 43]

访问成功。

至此，Eclipse下Maven工程多模块继承和聚合创建(详解)过程介绍完成，具体还的自己下去多多练习。
