使用IDEA基於Maven搭建多模塊聚合工程（springmvc+spring+mybatis整合）

文章有不當之處，歡迎指正，若是喜歡微信閱讀，你也能夠關注個人微信公衆號：好好學java，獲取優質學習資源。

終於有時間搞java了，今天使用IDEA基於maven搭建了多模塊聚合工程，通過了多番嘗試，終於成功啦！

注意：這裏是在原做者的基礎上改進的版本，原做者的版本的pom依賴存在問題，因此，這裏的依賴所有是我本身的依賴，圖片按照這個來徹底沒有問題！

一.工程目錄

下面是搭建以後的目錄

先看一下目錄關係

taotao-parent（父工程管理jar包的版本）

|--taotao-common（把通用的工具類打包）

|--taotao-manager（繼承父工程）

|-taotao-manager-pojo

  |-taotao-manager-dao

  |-taotao-manager-service

  |-taotao-manager-web（war包）

taotao-parent 爲項目的父工程，用來管理jar包及版本

taotao-common爲通用工程，繼承父工程，就是把通用的工具類打包

taotao-manager爲開發工程，一樣繼承父工程

其中，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service和taotao-manager-web均爲開發工程的一個子模塊，依賴於開發工程taotao-manager

前3個子模塊打成jar包，taotao-manager-web打成war包

二.建立工程

1.先建立一個空工程，步驟以下：
File——>new——>project

選擇Empty——>next

填寫工程名稱和位置，點擊finnish，完成了空工程的建立

2.建立父工程 taotao-parent，步驟以下：

File——>New——>Module

點maven，勾選archetype，選quickstart這項，而後Next下一步

填寫GroupId，通常爲組織名稱；填寫ArtifactId，爲項目名稱

選擇本地maven目錄及maven配置文件

填寫項目名稱及位置，點Finish，父工程建立完成

等待生成pom文件，修改打包方式爲pom，pom文件爲：

3.建立通用工程taotao-common

File——>New——>Module

點maven後直接next下一步

繼承taotao-parent,填寫ArtifactId,而後next下一步

填寫通用模塊名稱，點finish，通用模塊建立完成

開發模塊taotao-manager與通用模塊建立方式一致

taotao-common的pom.xml

</project>

4.建立開發模塊下的子模塊，分兩類介紹，taotao-manager-pojo，taotao-manager-dao，taotao-manager-service建立方式同樣，taotao-manager-web的建立有點差異

1）以taotao-manager-pojo爲例

File——>new——>module

選maven——>勾選archetype——>選quickstart這項——>點next

繼承taotao-manager，填寫ArtifactId

這裏注意改寫路徑，點finish，一個子模塊建立完成

taotao-manager-pojo的pom.xml

</project>

2）taotao-manager-web建立

一樣File——>New——>Module

只不過這裏選擇webapp這項（惟一不一樣的地方，其餘地方相似），點next下一步

一樣繼承taotao-manager

一樣須要改寫路徑，點擊finish，taotao-manager-web子模塊建立完成

5.接下來運行工程使用：tomcat7:run

右上角Edit Configurations

選maven

須要把taotao-parent等須要安裝的都安裝到本地倉庫。

最後運行，以下圖所示，就說明跑通了！

總結：

以前看別人的博客，有選擇portlet項，本身弄死活跑不通。

taotao-parent,taotao-manager-pojo,taotao-manager-dao,taotao-manager-service選擇quickstart那項；

taotao-common，taotao-manager啥都不選；

taotao-manager-web選擇webapp那項。

還要注意打包方式，jar，pom，war
