FastSpring学习笔记三（创建新闻发布信息的相关类）
熟悉了“FastSpring学习笔记二” 的介绍后，我们来实践一下吧，我们先在SQL Server中创建一个表，代码如下：
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[FS_PT_Announcement]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)drop table [dbo].[FS_PT_Announcement]GOCREATE TABLE [dbo].[FS_PT_Announcement] ( [ItemID] [int] IDENTITY (1, 1) NOT FOR REPLICATION NOT NULL , [ModuleID] [int] NOT NULL , [CreateByUser] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL , [CreatedDate] [datetime] NOT NULL , [Title] [nvarchar] (100) COLLATE Chinese_PRC_CI_AS NOT NULL , [MoreLink] [nvarchar] (150) COLLATE Chinese_PRC_CI_AS NOT NULL , [ExpireDate] [datetime] NOT NULL , [Description] [text] COLLATE Chinese_PRC_CI_AS NOT NULL , [Frequency] [int] NOT NULL , [IsActive] [int] NOT NULL , [Priority] [int] NOT NULL , [ClassID] [int] NOT NULL ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]GO
| PT_Announcement：公告信息表（在公告信息模块中用） | |||
| 字段名 | 类型 | 含义 | 备注 |
| ItemID | Int | 链接Id | 主键（自动编号） |
| ModuleID | Int | 所属模块ID | 决定该公告在那个模块中显示（模块ID：用户配置文件PortalCfg.xml中的模块表ID，以下皆同） |
| CreatedByUser | Nvarchar(100) | 创建者 | 记录创建和修改该公告的用户 |
| CreatedDate | Datetime | 创建时间 | 记录创建和修改该公告的时间 |
| Title | Nvarchar(100) | 名称 | |
| MoreLink | Nvarchar(150) | 更多细节的链接 | |
| MobileMoreLink | Nvarchar(150) | 移动细节链接地址 | 在“移动设备浏览器”上的更多细节链接地址 |
| ExpireDate | Datetime | 有效日期 | |
| Description | Nvarchar(2000) | 描述 | |
| Frequency | Int | 点击率 | |
| IsActive | Int | 是否激活 | 0为不显示，否则显示 |
| Priority | Int | 优先权 | 0为最低优先级，越大优先级越高 |
| ClassID | Int | 分类标识 | |
一、我们用上一章的方法，生成了2个文件：Announcement.cs和Announcement.hbm.xml
二、我们在DZ_Portal.App项目中添加几个文件夹，分别是：“BLL”、“DAL”、“Model”，它们分别代表不同的层，分别是：业务逻辑层、获取业务实体层、数据实体层（业务实体）。
三、修改Announcement.cs文件，最后结果如下：
using System;using System.Data;using System.Collections.Generic;using System.Text;using FastSpring.Base.Model;using FastSpring.Core.Model;using FastSpring.Common;namespace DZ_Portal.App.Model
...{
/**//// <summary>
///

}四、修改Announcement.hbm.xml文件，最后代码如下：
<?xml version="1.0" encoding="utf-8" ?><hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> <class name="DZ_Portal.App.Model.Announcement,DZ_Portal.App" table="PT_Announcement" lazy="false"> <id name="ItemID" column="ItemID" type="Int32" unsaved-value="0"> <generator class="native"/> </id> <property column="ModuleID" type="Int32" name="ModuleID" /> <property column="CreateByUser" type="String" name="CreateByUser" not-null="true" length="50" /> <property column="CreatedDate" type="DateTime" name="CreatedDate" not-null="true" /> <property column="Title" type="String" name="Title" not-null="true" length="100" /> <property column="MoreLink" type="String" name="MoreLink" not-null="true" length="150" /> <property column="ExpireDate" type="DateTime" name="ExpireDate" not-null="true" /> <property column="Description" type="String" name="Description" not-null="true" length="2147483647" /> <property column="Frequency" type="Int32" name="Frequency" not-null="true" /> <property column="IsActive" type="Int32" name="IsActive" not-null="true" /> <property column="Priority" type="Int32" name="Priority" not-null="true" /> <property column="ClassID" type="Int32" name="ClassID" not-null="true" /> </class></hibernate-mapping><!--1。HBM映射配置文件中“urn:nhibernate-mapping-2.0 ”需改为“urn:nhibernate-mapping-2.2”2。 <class name="类名,程序集名" table="Archives" >需改为<class name="类名,程序集名" table="Archives" lazy="false">，需要添加“lazy="false"”，不然会出现错误：he following types may not be used as proxies: xxxxx: method get_CreateDate should be virtual3。Spring.Data.NHibernate程序集变更为：Spring.Data.NHibernate12 (注意:Spring.Data.NHibernate程序集仍然存在,是对NHibernate1.0X的支持,Spring.Data.NHibernate12 为新增的支持NHibernate1.2.0GA的程序集)-->五、把这两个文件都拷贝到DZ_Portal.App项目下的Model文件夹下（因为它们都属于Model层）。
下一章我们将介绍另外两个层的类。
