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：
二、工程目录
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
Maven → Next
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
注意：因为common 与 parent 只有继承、但没有聚合的关系，所以在新建common项目的时候 Add as module to 要设置为 null。manager同理。
然后会出现如下如下界面：
修改打包方式为jar，taotao-common:pom.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <parent> 6 <artifactId>taotao-parent</artifactId> 7 <groupId>com.taotao</groupId> 8 <version>1.0-SNAPSHOT</version> 9 <relativePath>../taotao-parent/pom.xml</relativePath> 10 </parent> 11 <modelVersion>4.0.0</modelVersion> 12 <!--功能：通用的工具类，通用的pojo 打包方式jar--> 13 <!--继承parent工程--> 14 <artifactId>taotao-common</artifactId> 15 <dependencies> 16 <!--====================添加工具类包的依赖=======================--> 17 <!-- 时间操作组件 --> 18 <dependency> 19 <groupId>joda-time</groupId> 20 <artifactId>joda-time</artifactId> 21 </dependency> 22 <!-- Apache工具组件 --> 23 <dependency> 24 <groupId>org.apache.commons</groupId> 25 <artifactId>commons-lang3</artifactId> 26 </dependency> 27 <dependency> 28 <groupId>org.apache.commons</groupId> 29 <artifactId>commons-io</artifactId> 30 </dependency> 31 <dependency> 32 <groupId>commons-net</groupId> 33 <artifactId>commons-net</artifactId> 34 </dependency> 35 <!-- Jackson Json处理工具包 --> 36 <dependency> 37 <groupId>com.fasterxml.jackson.core</groupId> 38 <artifactId>jackson-databind</artifactId> 39 </dependency> 40 <!-- httpclient --> 41 <dependency> 42 <groupId>org.apache.httpcomponents</groupId> 43 <artifactId>httpclient</artifactId> 44 </dependency> 45 <!-- 单元测试 --> 46 <dependency> 47 <groupId>junit</groupId> 48 <artifactId>junit</artifactId> 49 </dependency> 50 <!-- 日志处理 --> 51 <dependency> 52 <groupId>org.slf4j</groupId> 53 <artifactId>slf4j-log4j12</artifactId> 54 </dependency> 55 </dependencies> 56 </project>
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
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <parent> 6 <artifactId>taotao-parent</artifactId> 7 <groupId>com.taotao</groupId> 8 <version>1.0-SNAPSHOT</version> 9 <relativePath>../taotao-parent/pom.xml</relativePath> 10 </parent> 11 <modelVersion>4.0.0</modelVersion> 12 13 <artifactId>taotao-manager</artifactId> 14 <packaging>pom</packaging> 15 <modules> 16 <module>taotao-manager-pojo</module> 17 <module>taotao-manager-dao</module> 18 <module>taotao-manager-service</module> 19 <module>taotao-manager-web</module> 20 </modules> 21 22 <dependencies> 23 <!--工程之间的依赖 manager依赖common--> 24 <dependency> 25 <groupId>com.taotao</groupId> 26 <artifactId>taotao-common</artifactId> 27 <version>1.0-SNAPSHOT</version> 28 </dependency> 29 </dependencies> 30 31 <build> 32 <!--配置插件--> 33 <plugins> 34 <plugin> 35 <groupId>org.apache.tomcat.maven</groupId> 36 <artifactId>tomcat7-maven-plugin</artifactId> 37 <configuration> 38 <port>8086</port> 39 <path>/</path> 40 </configuration> 41 </plugin> 42 </plugins> 43 </build> 44 </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：
taotao-manager-pojo:pom.xml pojo不需要依赖其它jar包
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <parent> 6 <artifactId>taotao-manager</artifactId> 7 <groupId>com.taotao</groupId> 8 <version>1.0-SNAPSHOT</version> 9 </parent> 10 <modelVersion>4.0.0</modelVersion> 11 12 <artifactId>taotao-manager-pojo</artifactId> 13 </project>
taotao-manager-dao:pom.xml dao的运行需要Mybatis等的支持，所以要添加依赖
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <parent> 6 <artifactId>taotao-manager</artifactId> 7 <groupId>com.taotao</groupId> 8 <version>1.0-SNAPSHOT</version> 9 </parent> 10 <modelVersion>4.0.0</modelVersion> 11 12 <artifactId>taotao-manager-dao</artifactId> 13 14 <dependencies> 15 <!--依赖pojo--> 16 <dependency> 17 <artifactId>taotao-manager-pojo</artifactId> 18 <groupId>com.taotao</groupId> 19 <version>1.0-SNAPSHOT</version> 20 </dependency> 21 22 <!--====================添加mybatis等数据库相关依赖===========================--> 23 <dependency> 24 <groupId>org.mybatis</groupId> 25 <artifactId>mybatis</artifactId> 26 </dependency> 27 <dependency> 28 <groupId>org.mybatis</groupId> 29 <artifactId>mybatis-spring</artifactId> 30 </dependency> 31 <dependency> 32 <groupId>com.github.miemiedev</groupId> 33 <artifactId>mybatis-paginator</artifactId> 34 </dependency> 35 <dependency> 36 <groupId>com.github.pagehelper</groupId> 37 <artifactId>pagehelper</artifactId> 38 </dependency> 39 <!-- MySql --> 40 <dependency> 41 <groupId>mysql</groupId> 42 <artifactId>mysql-connector-java</artifactId> 43 </dependency> 44 <!-- 连接池 --> 45 <dependency> 46 <groupId>com.alibaba</groupId> 47 <artifactId>druid</artifactId> 48 </dependency> 49 </dependencies> 50 </project>
taotao-manager-service:pom.xml
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 5 <parent> 6 <artifactId>taotao-manager</artifactId> 7 <groupId>com.taotao</groupId> 8 <version>1.0-SNAPSHOT</version> 9 </parent> 10 <modelVersion>4.0.0</modelVersion> 11 12 <artifactId>taotao-manager-service</artifactId> 13 14 <dependencies> 15 <!--依赖dao--> 16 <dependency> 17 <artifactId>taotao-manager-dao</artifactId> 18 <groupId>com.taotao</groupId> 19 <version>1.0-SNAPSHOT</version> 20 </dependency> 21 22 <!--加载spring--> 23 <dependency> 24 <groupId>org.springframework</groupId> 25 <artifactId>spring-context</artifactId> 26 </dependency> 27 <dependency> 28 <groupId>org.springframework</groupId> 29 <artifactId>spring-beans</artifactId> 30 </dependency> 31 <dependency> 32 <groupId>org.springframework</groupId> 33 <artifactId>spring-webmvc</artifactId> 34 </dependency> 35 <dependency> 36 <groupId>org.springframework</groupId> 37 <artifactId>spring-jdbc</artifactId> 38 </dependency> 39 <dependency> 40 <groupId>org.springframework</groupId> 41 <artifactId>spring-aspects</artifactId> 42 </dependency> 43 <dependency> 44 <groupId>org.springframework</groupId> 45 <artifactId>spring-context-support</artifactId> 46 </dependency> 47 </dependencies> 48 </project>
3.2 添加模块taotao-manager-web表现层，打包方式为war，同样taotao-manager上右键New → Module → Next，如下图所示，
只不过这里选择webapp这项不同，点next下一步
pom.xml
1 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 2 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> 3 <parent> 4 <artifactId>taotao-manager</artifactId> 5 <groupId>com.taotao</groupId> 6 <version>1.0-SNAPSHOT</version> 7 </parent> 8 <modelVersion>4.0.0</modelVersion> 9 <artifactId>taotao-manager-web</artifactId> 10 <packaging>war</packaging> 11 <name>taotao-manager-web Maven Webapp</name> 12 <url>http://maven.apache.org</url> 13 14 <!--添加依赖--> 15 <dependencies> 16 <dependency> 17 <groupId>com.taotao</groupId> 18 <artifactId>taotao-manager-service</artifactId> 19 <version>1.0-SNAPSHOT</version> 20 </dependency> 21 22 <!-- JSP相关 --> 23 <dependency> 24 <groupId>jstl</groupId> 25 <artifactId>jstl</artifactId> 26 </dependency> 27 <dependency> 28 <groupId>javax.servlet</groupId> 29 <artifactId>servlet-api</artifactId> 30 <scope>provided</scope> 31 </dependency> 32 <dependency> 33 <groupId>javax.servlet</groupId> 34 <artifactId>jsp-api</artifactId> 35 <scope>provided</scope> 36 </dependency> 37 <!-- 文件上传组件 --> 38 <dependency> 39 <groupId>commons-fileupload</groupId> 40 <artifactId>commons-fileupload</artifactId> 41 </dependency> 42 </dependencies> 43 <build> 44 <finalName>taotao-manager-web</finalName> 45 </build> 46 </project>
4. 右上角Edit Configurations
需要把taotao-parent、taotao-common等需要安装的都安装到本地仓库,然后点击下图中的绿色小三角就OK了。
