SSM框架搭建图文教程(推荐)

好久就想着好好搭建一个ssm框架，自己以后用也方便吧，但是最近的事真的是很多，很多事情都没有去干，有时候自己会怀疑一下人生自己该不该去做程序员，我是一个没毕业的学生，找工作真的是四处碰壁，感觉自己好难混，一个暑假换了3个公司。我其实就想找一个公司能干自己想干的技术，能学到自己想学到的东西，可是我发现太难了，几乎没有这样的公司。所以说在你不是很牛逼的时候，人得适应公司，而不是公司适应你。第一个公司的一个老程序员和我去公司必须能吃上饭，能吃上饭再想其他的东西，而我是个90后，我明白我的性格，一遇到难题就想逃避，可是逃避是最不好的道路，也是不能走的道路。希望刚毕业的同学能找到一个适合自己的工作。

一、我用的是idea

二、首先创建一个maven项目，结构如下:

三、开始写配置文件

pom文件
