好久就想著好好搭建一個ssm框架，自己以后用也方便吧，但是最近的事真的是很多，很多事情都沒有去干，有時候自己會懷疑一下人生自己該不該去做程序員，我是一個沒畢業的學生，找工作真的是四處碰壁，感覺自己好難混，一個暑假換了3個公司。我其實就想找一個公司能干自己想干的技術，能學到自己想學到的東西，可是我發現太難了，幾乎沒有這樣的公司。所以說在你不是很牛逼的時候，人得適應公司，而不是公司適應你。第一個公司的一個老程序員和我去公司必須能吃上飯，能吃上飯再想其他的東西，而我是個90后，我明白我的性格，一遇到難題就想逃避，可是逃避是最不好的道路，也是不能走的道路。希望剛畢業的同學能找到一個適合自己的工作。
一、我用的是idea
二、首先創建一個maven項目，結構如下:
三、開始寫配置文件
pom文件
