【转载】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。
e3-parent的pom.xml

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
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。
11、注意一下路径，是在WorkspaceforTest下面。
12、再在pom.xml下面添加<packaging>jar</packaging>，如下图所示。
在这个项目的pom文件如下代码所示。
e3-common的 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"

13、创建manager工程，与common工程的方法一样。
File——>New——>module——>Maven
14、再在pom.xml下面添加<packaging>pom</packaging>，如下图所示。
e3-common的 pom.xml文件
<?xml version="1.0" encoding="UTF-8"?>

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。
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。

20、最后创建e3-manager-web工程，创建过程都与上面的四个过程一样。只是有一个地方需要注意，下面的截图会提示。
选中e3-manager——>右击鼠标——>New——Module，因为e3-manager-web是e3-manager的子工程。
只是下面需要注意一下。
21、再在pom.xml下面添加<packaging>war</packaging>，如下图所示。
22、e3-manager-web的pom.xml文件
<?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"

</project>
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
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。
