Spring4 SpringMVC Hibernate4 Freemaker 整合例子

前话：

写了半年的Flex，也就是一个做一个WEB的视频监控浏览端，已经初步成型，现在是要做一个管理平台，于是终于又要用回JAVA了，但是一切都变的陌生了，

比如写个方法或者定义一个变量，总是会用Flex的语法去写，以前都是用Struts2 Hibernate Spring框架的，现在据说springMVC更流行了，于是花了这一周时间入了下门，感觉

确实不错，我是看的这个系列教程，跟开涛学SpringMvc http://jinnianshilongnian.iteye.com/category/231099，写的很赞，通俗易懂，非常感谢！

后来顺便也看了下这个前端开发框架Bootstrap也很不错，简直是后端开发人员的福音啊，并且我发现改版后的CSDN登录界面也用到了这个框架，所以学习了下，也是在

一个系列博客中看的，http://www.cnblogs.com/aehyok/p/3404867.html#title02 其实是跟Bootstrap中文网的教程差不多，但是在博客中看比较集中，并且目录清晰，当时在中文网看的12栅格布局是真心没看懂，后来在这位仁兄的博

客中看懂了，在这里非常感谢！

今天周五，所以简单的整合了一下来熟悉这周看的东西

老规矩（有图有真相），先看下相关效果图吧：

登录界面：（Bootstrap的样式还挺赞的吧）

主页面：

添加：

修改：（上面的修改和删除你要点击一下某一行，才能进行操作）

项目目录结构：

代码还是挺多的，不贴了

DEMO源码到这里下载吧：http://download.csdn.net/detail/soanl/7391345

说明：在项目的doc下有数据库文件，

新建数据库名为 db_shf，编码设为utf-8，然后导入就行

运行 http://你的ip:端口port/WebApp 用户名：admin，密码：admin

下周开始把mina学习下，因为公司项目之间的通信都是用socket通信的，在这个管理平台也要用到socket同主服务器通信
