使用IDEA基于Maven搭建多模块聚合工程（springmvc+spring+mybatis整合）

文章有不当之处，欢迎指正，如果喜欢微信阅读，你也可以关注我的微信公众号：好好学java，获取优质学习资源。

终于有时间搞java了，今天使用IDEA基于maven搭建了多模块聚合工程，经过了多番尝试，终于成功啦！

注意：这里是在原作者的基础上改进的版本，原作者的版本的pom依赖存在问题，所以，这里的依赖全部是我自己的依赖，图片按照这个来完全没有问题！

一.工程目录

下面是搭建之后的目录
这里写图片描述

先看一下目录关系

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

二.创建工程

1.先创建一个空工程，步骤如下：
File——>new——>project
这里写图片描述

选择Empty——>next
这里写图片描述

填写工程名称和位置，点击finnish，完成了空工程的创建
这里写图片描述

2.创建父工程 taotao-parent，步骤如下：

File——>New——>Module
这里写图片描述

点maven，勾选archetype，选quickstart这项，然后Next下一步
这里写图片描述

填写GroupId，一般为组织名称；填写ArtifactId，为项目名称

这里写图片描述

选择本地maven目录及maven配置文件

这里写图片描述

填写项目名称及位置，点Finish，父工程创建完成
这里写图片描述

等待生成pom文件，修改打包方式为pom，pom文件为：

3.创建通用工程taotao-common

File——>New——>Module

这里写图片描述

点maven后直接next下一步

这里写图片描述

继承taotao-parent,填写ArtifactId,然后next下一步

这里写图片描述

填写通用模块名称，点finish，通用模块创建完成
这里写图片描述

开发模块taotao-manager与通用模块创建方式一致

4.创建开发模块下的子模块，分两类介绍，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service创建方式一样，taotao-manager-web的创建有点差别

1）以taotao-manager-pojo为例

File——>new——>module

这里写图片描述

选maven——>勾选archetype——>选quickstart这项——>点next
这里写图片描述

继承taotao-manager，填写ArtifactId
这里写图片描述

这里注意改写路径，点finish，一个子模块创建完成

2）taotao-manager-web创建

同样File——>New——>Module

只不过这里选择webapp这项（唯一不同的地方，其他地方类似），点next下一步
这里写图片描述

同样继承taotao-manager
这里写图片描述

同样需要改写路径，点击finish，taotao-manager-web子模块创建完成

5.接下来运行工程使用：tomcat7:run

右上角Edit Configurations
这里写图片描述
选maven

这里写图片描述
需要把taotao-parent等需要安装的都安装到本地仓库。

最后运行，如下图所示，就说明跑通了！

这里写图片描述

总结：

之前看别人的博客，有选择portlet项，自己弄死活跑不通。

taotao-parent,taotao-manager-pojo,taotao-manager-dao,taotao-manager-service选择quickstart那项；

taotao-common，taotao-manager啥都不选；

taotao-manager-web选择webapp那项。

还要注意打包方式，jar，pom，war
