Intellij 基于Maven聚合工程 SSM框架整合

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。
