NetPetshop 研究学习（一）

NetPetshop 研究学习（一）

1 NetPetshop是采用了数据库持久层采用O/RM工具iBatisNet。
采用了典型的三层结构。分层如下：
数据访问层：NPetshop.Service，NPetshop.Persistence，NPetshop.Domain
业务逻辑层：NPetshop.Presentation
表示层：NPetshop.Web
2 以用户帐户注册页面的为例说明调用关系：
D:/NPetShop/NPetshop/NPetshop.Web/Default.aspx.cs
调用如下类：
D:/NPetShop/NPetshop/NPetshop.Web/UserControls/Accounts/NewAccount.ascx.cs
调用如下类：
D:/NPetShop/NPetshop/NPetshop.Presentation/UserActions/AccountAction.cs
调用如下类：
D:/NPetShop/NPetshop/NPetshop.Service/AccountService.cs
调用如下类：
D:/NPetShop/NPetshop/NPetshop.Persistence/MapperDao/Accounts/AccountSqlMapDao.cs
调用如下类：
D:/NPetShop/NPetshop/NPetshop.Persistence/MapperDao/BaseSqlMapDao.cs

3 如何读取dao.config，SqlMap.config配置文件

D:/NPetShop/NPetshop/NPetshop.Service/ServiceConfig.cs
如下代码：
static public ServiceConfig GetInstance()
{
if (_instance == null)
{
lock (_synRoot)
{
if (_instance == null)
{
ConfigureHandler handler = new ConfigureHandler(ServiceConfig.Reset);

DomDaoManagerBuilder builder = new DomDaoManagerBuilder();
builder.ConfigureAndWatch("dao.config", handler);

_instance = new ServiceConfig();
_instance._daoManager = IBatisNet.DataAccess.DaoManager.GetInstance("SqlMapDao");
}
}
}
return _instance;
}

5 利用<asp:repeater/>控件绑定数据
<asp:repeater id="RepeaterItems" runat="server">
<headertemplate>
<table cellpadding="0" cellspacing="1">
<tr class="gridHead">
<td>Line</td>
<td>Item</td>
<td>Product</td>
<td>Price</td>
<td>Quantity</td>
<td>Subtotal</td>
</tr>
</headertemplate>
<itemtemplate>
<tr class="gridItem">
<td><%# DataBinder.Eval(Container.DataItem, "LineNumber") %></td>
<td><%# DataBinder.Eval(Container.DataItem, "Item.Id") %></td>
<td><%# DataBinder.Eval(Container.DataItem, "Item.Product.Id") %></td>
<td class="num"><%# DataBinder.Eval(Container.DataItem, "Item.ListPrice", "{0:c}") %></td>
<td class="num"><%# DataBinder.Eval(Container.DataItem, "Quantity") %></td>
<td class="num"><%# DataBinder.Eval(Container.DataItem, "Total", "{0:c}") %></td>
</tr>
</itemtemplate>
<footertemplate></table></footertemplate>
</asp:repeater>
