Intellij 基于Maven聚合工程 SSM框架整合

2019-03-21  本文已影响0人  054ab278d5d9

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。

五、intellij maven工程运行

运行项目后,在控制台可以看到如下图所示。

 去浏览器输入地址后可以看到项目运行成功。
