第一次写后端的我，上网找了很多教程，很多细节都没有找到，自己做的时候发现有好多坑，下面填平了我遇到的坑整理的搭建流程，只要跟着教程做，你就能搭建一个完整的ssm框架
首先create project

creat_project_1.png
填写包名啥的，自由发挥
creat_project_2.png
在这一步之前需要安装且配置maven
creat_project_3.png
修改idea指向maven的setting文件
creat_project_4.png
修改idea指向存放的资源文件夹，原本是指向.m文件，由于我找不到这个傻逼文件在哪，所以。。。
指向自己创建的文件也避免了把资源文件放在c盘
creat_project_5.png
在settings.xml中添加阿里代理
maven_setting.png
在settings.xml中添加指向本地资源文件
maven_setting_2.png
最后finish就创建好了
creat_project_6.png
项目创建好后下面这个按钮先别按，还没配置好会报错
project_setting_3.png
File -> Settings 中选中自己安装的jdk
project_setting_4.png
上面maven setting文件和本地资源文件路径一定要弄好，jdk选好，不然import资源的时候会疯狂报错，不要问我怎么知道的
打开pom.xml文件，复制之后全部替换

替换完就能import了，如下图操作

project_setting_1.png
如果出现下面的报错，重启一下编辑器rebuild一下项目
project_setting_5.png
project_setting_6.png

注意！！！！！！！！

maven版本不要使用3.6.2以上的版本，必定爆炸，血的教训

3.6.2以上的九成是不行的，上面我截的图是3.6.3，是因为我莫名其妙的成功了一次截的图，之后就没成功

不过头铁的也可以试一下，顺便贴个教程，懒得写╮(╯_╰)╭
旧版本maven下载教程

如果import成功，这样什么都没有ssm项目就搭建好了

如果你还是出现了

project_setting_5.png
就去看看log文件
project_setting_7.png
文本编辑器打开，拉到最下面应该就能看到你项目的bug在哪了
project_setting_8.png
