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
