Spring4 SpringMVC Hibernate4 Freemaker 整合样例
作者：互联网
更正改动（2014-05-30 13:47:22）：有的IDE中web.xml会报这个错：
cvc-complex-type.2.4.a: Invalid content was found starting with element 'init-param'. One of '{"http://
xmlns.jcp.org/xml/ns/javaee":enabled, "http://xmlns.jcp.org/xml/ns/javaee":async-supported, "http://
xmlns.jcp.org/xml/ns/javaee":run-as, "http://xmlns.jcp.org/xml/ns/javaee":security-role-ref, "http://
xmlns.jcp.org/xml/ns/javaee":multipart-config}' is expected.
你能够无视它。可是假设认为不舒服的话。能够将<load-on-startup>1</load-on-startup>放到<init-param>这个节点的后面
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。如今是要做一个管理平台，于是最终又要用回JAVA了，可是一切都变的陌生了，
比方写个方法或者定义一个变量。总是会用Flex的语法去写，曾经都是用Struts2 Hibernate Spring框架的，如今据说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。写的非常赞，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也非常不错，简直是后端开发者的福音啊，而且我发现改版后的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 事实上是跟Bootstrap中文网的教程几乎相同。可是在博客中看比較集中，而且文件夹清晰，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：

改动：（上面的改动和删除你要点击一下某一行。才干进行操作）
项目文件夹结构：

代码还是挺多的，不贴了
DEMO源代码到这里下载吧：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。然后导入即可
执行 http://你的ip:端口port/WebApp username：admin，密码：admin
下周開始把mina学习下。由于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server通信
