可以看到，这两个类并没有访问数据库，也没有实现真正的业务逻辑，而不过是“捏 造”了一些数据骗骗我们的表示层而已。
最后，我们要建立一个生成业务逻辑模型的生成器，用来实现表示层和业务逻辑层的解 耦。当然，为了简化复杂度，这里没有使用依赖注入机制。下面是我们生成器的代码，这个类是直接放在Models下的。
ServiceBuilder.cs:
Code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MVCDemo.Models.Interfaces;
using MVCDemo.Models.MockModels;
namespace MVCDemo.Models
{
/// <summary>
/// 服务组件生成类，用于生成业务服务组件
/// </summary>
public sealed class ServiceBuilder
{
/// <summary>
/// 创建分类服 务组件
/// </summary>
/// <returns>分类服务
