这次主要是通过一个示例基本介绍Web Service Software Factory各个层次的开发
一、建立模板
文件—新建—项目，选择Web Service Software Factory (ASMX)并建立ASMX Service 模板如下图
建立之后我们就能看到由模板帮我们建立的解决方案，分别是业务组件层、数据访问层、服务层以及测试和客户端，这些层次的相关的作用了功能已经在上次中有提到。
二、添加数据库连接
这个很重要，任何的发起都是以它为先决条件的
我们在Service层中右键选择Service Factroy-DataAccess—Add DataBase Connection,在设置向导中建立数据库的连接
这个步骤其实就在web.Config中建立连接字符串
三、添加业务实体类
在CustomerService.BusinessEntities项目中右键选择Service Factroy-DataAccess—Create businessEntities from DataBase,有人可能会想到，难道集成了ORM,其实不然，这个我在后续中会介绍，数据库表直接的数据关系，那它怎么处理呢，其实大家看了就知道了，他也可以将视图生成实体类，从这里我们可以考虑我们可以把数据表直接的关系写在视图中，这样就可以实现关系了
这样他就自动帮我们生成了实体类Customer类
public partial class Customer { public Customer() { } public Customer(System.Int32 customerId, System.String firstName, System.String lastName) { this.customerIdField = customerId; this.firstNameField = firstName; this.lastNameField = lastName; } private System.Int32 customerIdField; public System.Int32 customerId { get { return this.customerIdField; } set { this.customerIdField = value; } } private System.String firstNameField; public System.String firstName { get { return this.firstNameField; } set { this.firstNameField = value; } } private System.String lastNameField; public System.String lastName { get { return this.lastNameField; } set { this.lastNameField = value; } } } class FindCustomerAction { public CustomerList Execute(Customer criteria) { CustomerList list = new CustomerList(); list.Add(new Customer(20, "Kim", "Abercrombie")); list.Add(new Customer(21, "Andy", "Jacobs")); list.Add(new Customer(22, "Agostino", "Martino")); list.Add(new Customer(23, "Qiang", "Wang")); return list; } } [System.SerializableAttribute()] [System.Xml.Serialization.XmlRootAttribute(Namespace = "http://CustomerService.DataTypes/2006/10", IsNullable = false)] public class Customer { private int iD; private string firstName; private string lastName; public int ID { get { return this.iD; } set { this.iD = value; } } public string FirstName { get { return this.firstName; } set { this.firstName = value; } } public string LastName { get { return this.lastName; } set { this.lastName = value; } } }using CustomerService.ServiceContracts;using CustomerService.BusinessLogic;namespace CustomerService.ServiceImplementation{ class CustomerManagerAdapter : ICustomerManager { ICustomerManager Members#region ICustomerManager Members /**//// <summary> /// Implement the FindCustomer operation /// </summary> /// <param name="request">Request message contract</param> /// <returns>Response message contract</returns> public SearchResponse FindCustomer(SearchRequest request) { // translate the data type to a business entity Translators.TranslateBetweenCustomerAndCustomer translator = new Translators.TranslateBetweenCustomerAndCustomer(); CustomerService.BusinessEntities.Customer criteria = translator.TranslateCustomerToCustomer(request.Criteria); // invoke the business action FindCustomerAction action = new FindCustomerAction(); CustomerService.BusinessEntities.CustomerList customers = action.Execute(criteria); // translate customer list into a data type Translators.TranslateBetweenCustomerListAndCustomerList listTranslator = new Translators.TranslateBetweenCustomerListAndCustomerList(); CustomerService.DataTypes.CustomerList list = listTranslator.TranslateCustomerListToCustomerList(customers); // create a response and return it SearchResponse response = new SearchResponse(); response.Customers = list; return response; } /**//// <summary> /// Implement the GetCustomer operation /// </summary> /// <param name="request">Customer ID</param> /// <returns>Customer data type</returns> public CustomerService.DataTypes.Customer GetCustomer(int request) { // invoke the business action GetCustomerAction action = new GetCustomerAction(); CustomerService.BusinessEntities.Customer customer = action.Execute(request); // translate the business entity into a data type Translators.TranslateBetweenCustomerAndCustomer translator = new Translators.TranslateBetweenCustomerAndCustomer(); CustomerService.DataTypes.Customer response = translator.TranslateCustomerToCustomer(customer); return response; } #endregion }} using (localhost.CustomerManager proxy = new localhost.CustomerManager()) { localhost.SearchRequest request = new localhost.SearchRequest(); request.Criteria = new localhost.Customer(); request.Criteria.LastName = SearchText.Text; localhost.SearchResponse response = proxy.FindCustomer(request); ResultsGrid grid = new ResultsGrid(response.Customers); grid.ShowDialog(this); }
