好大家好多的網絡服務,從而多單
我有一個項目,倍數Web服務,所以我創造了性能的各種單例類的想法。現在我想創建一個單獨的類,並且有我的web服務
例如
public static WebServiceMaster
{
internal ServiceX WebX;
internal ServiceY WebY;
......
public static WEbServiceMaster GetInstance()
.....
}
什麼想想的實例? 是那麼糟糕?
好了,終於做到這一點。我知道這是不完美的
Public NotInheritable Class ServiceProxySingleton
Private _services As IDictionary(Of ProxyServicesEnum, IServiceDispatcher) = New Dictionary(Of ProxyServicesEnum, IServiceDispatcher)
Private _dbRepository As IDACommon
Private Sub New()
_dbRepository = New DACommon()
LoadServices()
End Sub
Private Sub LoadServices()
_services.Add(ProxyServicesEnum.eActivity, New ActivityServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eAvailability, New AvailabilityServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eBrochure, New BrochureServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eInformation, New InformationServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eMeetingRoom, New MeetingRoomServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eMembership, New MembershipServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.eName, New NameServiceImp(_dbRepository))

_services.Add(ProxyServicesEnum.eStayHistory, New StayHistoryServiceImp(_dbRepository))
_services.Add(ProxyServicesEnum.ePostXml, New PostXmlServiceImp(_dbRepository, ConfigurationServiceSingleton.GetInstance.GetPostXmlConfig))
_services.Add(ProxyServicesEnum.eOxiHttp, New OxiServiceImp(_dbRepository))
End Sub
Public ReadOnly Property Service(ByVal serviceEnum As ProxyServicesEnum) As Object
Get
If _services.ContainsKey(serviceEnum) Then
Return _services.Item(serviceEnum)
End If
Return Nothing
End Get
End Property
Public ReadOnly Property GetMeta(ByVal serviceEnum As ProxyServicesEnum) As IDictionary(Of String, MethodIdentityAttribute)
Get
If _services.ContainsKey(serviceEnum) Then
Return _services.Item(serviceEnum).MetaInfo
End If
Return Nothing
End Get
End Property
Public Shared Function GetInstance() As ServiceProxySingleton
Return NestedPrWireService._instance
End Function
Class NestedPrWireService
Friend Shared ReadOnly _instance As ServiceProxySingleton = New ServiceProxySingleton()
Shared Sub New()
End Sub
End Class
End Class
意見和批評,歡迎
看看multiton,也許這就是你要找的。 http://en.wikipedia.org/wiki/Multiton_pattern#C.23 @Carlos和btw singelton不是一種表演模式。也許你應該閱讀有關它也 – sra 2011-05-14 06:10:29
