如何实现像IAbpSession一样的属性注入？

Question

我正在尝试实现我自己的自定义 IAbpSession，但我不知道如何实现与 IAbpSession 相同的 属性 注入。 我的 AppServiceBase 如下所示：

public abstract class EdwardAppServiceBase : ApplicationService
{
    public TenantManager TenantManager { get; set; }

    public UserManager UserManager { get; set; }

    protected EdwardActiveUnitOfWork EdwardActiveUnitOfWork => (EdwardActiveUnitOfWork)UnitOfWorkManager.Current;

    protected IEdwardSession EdwardSession { get; set; } 
    // protected IEdwardSession EdwardSession => AbpSession as IEdwardSession;

    protected SensingStoreCloudAppServiceBase()
    {
        // EdwardSession = NullEdwardSession.Instance;
        LocalizationSourceName = SensingStoreCloudConsts.LocalizationSourceName;
    }
}

如果我取消注释 EdwardSession = NullEdwardSession.Instance;，我总是得到 NullEdwardSession 而不是 IEdwardSession 实现：EdwardSession。

我只能做到AbpSession as IEdwardSession.

ABP如何注入IAbpSession并在ApplicationService中设置其值？

Answer 1

ABP 使用 Castle Windsor 作为依赖并且 property injection:

How properties are injected

Property injection of dependencies is designed to be done during component activation when a component is created. The responsibility of determining which properties are used for injection is fulfilled by default through PropertiesDependenciesModelInspector - a IContributeComponentModelConstruction implementation which uses all the following criteria to determine if a property represents a dependency:

• Has 'public' accessible setter
• Is an instance property
• If ComponentModel.InspectionBehavior is set to PropertiesInspectionBehavior.DeclaredOnly, is not inherited
• Does not have parameters
• Is not annotated with the Castle.Core.DoNotWireAttribute attribute

所以做到 public:

// protected IEdwardSession EdwardSession { get; set; }
public IEdwardSession EdwardSession { get; set; }
