maven配置spring mvc+hibernate+spring框架

2023-07-31 22:18:28

作为一名刚出茅草屋的新手小白写的框架，仅适合新手小白借鉴，大神勿喷，谢谢......

前天刚知道spring mvc这个框架现在也很流行，决定用它代替struts2来写我的毕业设计。

...作为一名新手小白，钻研了俩天，稀里糊涂的继续运行测试，竟然测试通过了...太神奇了...目录真是比以前的干净了多少.

只是一个框架，并没有开始写java类...(其实spring mvc怎么替代struts2控制，正在学习中...)

我用的myeclipse2014，创建web项目，加maven支持。

废话少说，看下面：

不会写log4j，因为不会......额，junit也刚开始学，测试就是加入tomcat运行呗.....泪奔、

说实话，现在刚实习一个多月，在学校学到的东西到公司大概就能用到30%，至少我是这样，

不过这30%必不可少，因为如果你不会，你可能连代码、框架都看不懂，更何况去写了。

好了，如果不会，全部复制粘贴，理理思路，我继续学习，如果你看不懂，我明确告诉你：别问我，我也就比你懂那么一丝丝......
