以前写java的时候就velocity ，人家问偶struts的时候嘿嘿，只知道eclipse是可以配置的，其他木然
最近被迫写c#，也顺手找到了下，发现nvelocity 估计以后人家问偶webui的时候也只有继续木然了。
借鉴前人的，改了下。
测试下来速度还是可以的
目标
基础接口，写php弄smarty留下来遗产，java在用，c#也就继续下去吧。

下面是生成静态页面的东东，估计是上面那个是吃中午饭前完成的。下面是吃完饭回来写，哎，人老了。

2个补充类，一个示例类，一个模板。

protected LDCMS.Core.Service.IServiceFactory ServiceFatory
{
get
{

}
}
//用于存储全局使用的变量
public class CacherInfo
{
//随便放点你需要放置的全局要用的东西
}
//一个实现类
public class CatalogListCacheResolver:BaseHtmlCacheResolver
{
private LDCMS.Core.Service.ICatalogService _catalogService;
public CatalogListCacheResolver()
{
_catalogService = ServiceFatory.getCatalogManager();
}
//示例
public Catalog GetCatalog(int id)
{
return _catalogService.GetById(id);
}
}
//html.vm
#set($entity = $catalog.GetCatalog(1))
栏目名称：$entity.Name</b>
栏目位置:$entity.Link</b>
先用着吧。
不过nvelocity 全局宏还是不知道怎么加载。头痛中
nvelcotiy 用的是castle的。他的关于宏的包还木弄明白。
至于spring 这个东西哎。。spring.net 还木弄明白的，所以spring+velocity+hibernate这个东西可能不太可能翻译成
spring.net+nvelocity+nhibernate了。不过junit log4j 变成nunit,log4net 还在继续发挥他们功能。
有空再把他们2个抓来show下。
