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; }
}
}
四、建立自己的业务逻辑层
因为使用的是这个框架所以我们就把业务逻辑放在CustomerService.BusinessEntities 层中，我们新建一个FinfCustomerAction类
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;
}
}
五、定义数据类型
就能生成
[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;
}
}
}
这个是什么用，我会在下章节中描述
六、定义消息类型
七、建立消息协议
八、建立服务协议解释器
九、在执行服务上添加适配器
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
}
}
十、发布服务
十一、发布客户端
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);
}
十二、总结：
这是关于Web Service Software Factory的一次入门的实例，现在只牵涉到怎样去实现，里面牵涉的内容很多，下次就详细的描述各个层次之间设计的原理。
