Web Service Software Factory 入门

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。
