如何在 StructureMap Registy 构造函数中获取某种类型的实例(在不同的注册表中注册)?我想使用这样的代码:
public RepositoriesRegistry()
{
IApplicationSettings lApplicationSettings =
ObjectFactory.GetInstance<IApplicationSettings>();
Debug.Assert(lApplicationSettings != null);
const string cSupportedDevicesConnectionString =
"metadata=res://*/Models.SupportedDevices.Database.SupportedDevicesModel.csdl|res://*/Models.SupportedDevices.Database.SupportedDevicesModel.ssdl|res://*/Models.SupportedDevices.Database.SupportedDevicesModel.msl;provider=System.Data.SqlClient;provider connection string=\"{0}\"";
string lSupportedDevicesConnectionString =
string.Format(cSupportedDevicesConnectionString, lDatabaseConnectionString);
SupportedDevicesEntities lSupportedDevicesEntities =
new SupportedDevicesEntities(lSupportedDevicesConnectionString);
ForRequestedType<SupportedDevicesEntities>().TheDefault.IsThis(
lSupportedDevicesEntities);
ForRequestedType<ISupportedDevicesRepository>().TheDefault.IsThis(
new SupportedDevicesRepository(lSupportedDevicesEntities));
}
IApplicationSettings 是应用程序设置的接口。实现此接口的具体类型(当前为 ConfigFileApplicationSettings 类)在另一个注册表中注册,如下所示:
public ApplicationServicesRegistry()
{
ForRequestedType<IApplicationSettings>().TheDefault.IsThis(
new ConfigFileApplicationSettings());
}
并且两个注册表都在 Bootstrapper 中注册:
#region IBootstrapper Members
public void BootstrapStructureMap()
{
ObjectFactory.Initialize(InitalizeStructureMapContainer);
}
#endregion
#region Private properties
private static bool HasStarted { get; set; }
#endregion
#region Private methods
private void InitalizeStructureMapContainer(IInitializationExpression x)
{
x.IgnoreStructureMapConfig = true;
x.AddRegistry<ViewModelRegistry>();
x.AddRegistry<ApplicationServicesRegistry>();
x.AddRegistry<RepositoriesRegistry>();
x.AddRegistry<DataOperationsRegistry>();
}
#endregion
当我尝试在注册表构造函数中获取 IApplicationRegisty 的实例时,我遇到了错误(当然)。我不完全了解如何以正确的方式使用 StructureMap。也许我应该以不同的方式做这件事。但无论如何,我可以在 Registry 构造函数中获得某种类型的早期注册实例吗?
