一、工程介绍

淘淘网上商城是一个综合性的B2C平台，类似京东商城、天猫商城。会员可以在商城浏览商品、下订单，以及参加各种活动。
管理员、运营可以在平台后台管理系统中管理商品、订单、会员等。
客服可以在后台管理系统中处理用户的询问以及投诉。

具体实现：

具体实现

二、工程目录

结构 
taotao-parent（父工程管理jar包的版本）

   |-taotao-common（把通用的工具类打包）

   |-taotao-manager（继承父工程）

      |-taotao-manager-pojo

      |-taotao-manager-dao

      |-taotao-manager-service

      |-taotao-manager-web（war包）

taotao-parent 为项目的父工程，用来管理jar包及版本

taotao-common为通用工程，继承父工程，就是把通用的工具类打包

taotao-manager为开发工程，同样继承父工程

其中，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service和
taotao-manager-web均为开发工程的一个子模块，依赖于开发工程taotao-manager

前3个子模块打成jar包，taotao-manager-web打成war包

三、创建工程

1. 创建taotao-parent父类工程，后面所有的工程全部继承该工程
File → New → Project

创建.png

Maven → Next

next.png 唯一标识.png taotao-parent.png

创建完后，删除生成的src目录，修改打包方式为pom，taotao-parent:pom.xml

maven中有3种工程：

  1. pom工程：用在父级或聚合工程中，用来做jar包的版本控制。
  2. war工程：会打包成war，发布在服务器上。如网站或服务。
  3. jar工程：打包成jar用作jar包使用。

2. 创建通用工程taotao-common，继承父工程，保存的是通用的工具类及pojo，打包方式jar包
在taotao-parent文件上右击创建新的model，和创建maven类似不需要勾选信息，taotao-parent→ New → Module

New一个Module.png next.png

然后会出现如下如下界面：

image.png 修改后.jpg

修改打包方式为jar，taotao-common: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"

        </dependency>
    </dependencies>

3. 创建taotao-manager聚合工程，打包方式pom，里面有一堆模块。创建工程类似taotao-common的过程，在taotao-parent文件上右击创建新的model，和创建maven类似不需要勾选信息：taotao-parent→ New → Module → Next → taotao-manager

taotao-manager：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/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>taotao-parent</artifactId>
        <groupId>com.taotao</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../taotao-parent/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>taotao-manager</artifactId>

    <modules>
        <module>taotao-manager-pojo</module>
        <module>taotao-manager-dao</module>
        <module>taotao-manager-service</module>
        <module>taotao-manager-web</module>
    </modules>

    <dependencies>
        <!--工程之间的依赖 manager依赖common-->
        <dependency>
            <groupId>com.taotao</groupId>
            <artifactId>taotao-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

    <build>
        <!--配置插件-->
        <plugins>
            <plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <configuration>
                    <port>8086</port>
                    <path>/</path>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

3.1 添加模块，打包方式都为jar，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service创建方式一样

taotao-manager-pojo

在taotao-manager上右键New → Module → Next → taotao-manager-pojo，过程类似mall-common的创建但是路径选择需要重写填写，如下图：

路径注意

taotao-manager-pojo:pom.xml pojo不需要依赖其它jar包

<?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/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>taotao-manager</artifactId>
        <groupId>com.taotao</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>taotao-manager-pojo</artifactId>
</project>

taotao-manager-dao:pom.xml dao的运行需要Mybatis等的支持，所以要添加依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
