使用IntelliJ IDEA创建Maven聚合工程、创建resources文件夹、ssm框架整合、项目运行一体化

一、创建一个空的项目作为存放整个项目的路径

1、选择 File——>new——>Project ——>Empty Project

2、WorkspaceforTest为项目存放文件夹。

二、maven继承：创建父-子项目，聚合工程

比如整个项目。以一个项目来演示。

|--e3-parent：父工程，打包方式pom，管理jar包的版本号。项目中所有工程都应该继承父工程。

　　|--e3-common：通用的工具类通用的pojo。打包方式jar

　　|--e3-manager：服务层工程。聚合工程。Pom工程

　　　　|--e3-manager-dao：打包方式jar

　　　　|--e3-manager-pojo：打包方式jar

　　　　|--e3-manager-interface：打包方式jar

　　　　|--e3-manager-service：打包方式：jar

　　　|--e3-manager-web：表现层工程。打包方式war

1、创建maven父工程 e3-parent

File——>New ——>Module.. ——>Maven

2、GroupId一般为公司域名倒过来写。ArtifactId写工程名字。

3、Maven home directory 在这里我选择自己安装的maven，还有User settings file 选择好本地仓库。

4、注意下e3-parent的项目路径，在WorkspaceforTest下面。

5、在e3-parent的pom.xml文件下添加<packaging>pom</packaging>,e3-parent是打成pom文件的。

6、就可以pom文件添加各种依赖了。在这里我的e3-parent的pom.xml文件如下。

7、创建e3-common，e3-common继承父工程parent。而且为了与eclipse下面一样一种好看，common工程的目录也是在WorkspaceforTest目录下，但是是继承了parent工程

File——>New——>module——>Maven

使用IntelliJ IDEA创建Maven聚合工程、创建resources文件夹、ssm框架整合、项目运行一体化

8、common工程也是在WorkspaceforTest目录下的，所以要在Add as module to选项中选择None,如下图所示

9、Parent 中选择继承的父工程e3-parent，如下图所示，再写好ArtifactId.

10、选择maven，如果没有发生改变，就可以直接下一步。

15,来开始创建e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程最终都是打成jar包的，创建过程都是一样的，下面就只写出一个工程的创建过程。

以e3-manager-pojo为例。

16、选中e3-manager——>右击鼠标——>New——Module，因为e3-manager-pojo是e3-manager的子工程。

使用IntelliJ IDEA创建Maven聚合工程、创建resources文件夹、ssm框架整合、项目运行一体化

17、再在pom.xml下面添加<packaging>pom</packaging>，如下图所示。

18、e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程都是这样创建。

19、e3-manager-pojo、e3-manager-dao、e3-manager-interface、e3-manager-service,这四个工程的pom.xml文件。

23、好了。到此maven聚合工程创建完成。

三、maven工程下创建resources文件夹

步骤：File——>Project Struture——>Modules——>maven工程，如果没有maven工程就点+号来添加

使用IntelliJ IDEA创建Maven聚合工程、创建resources文件夹、ssm框架整合、项目运行一体化

选择到创建resources文件夹的路径，比如图上的选择到main，右击鼠标，选择New Folder新建文件夹resources

再选择resources，右击鼠标选择Resources，可以看到resources文件夹的图标和之前不一样了，就是这样创建一个resources文件夹。再点Ok保存退出。

很明图标都不一样了。

四、整合ssm框架

直接看项目路径，直接上代码，不懂ssm框架整合的可以百度学习下。
