Spring4 SpringMVC Hibernate4 Freemaker 整合样例

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：

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
