Question

我有一个由Simple.Data支持的类和一个类似ActiveRecord的接口，这个类的对象大多数时候是从静态方法创建的。我正在使用Castle Windsor迈出第一步，并希望在我的项目中使用它的Logging Facility（使用属性注入）。如何使用FindOrCreateByName而不是构造函数接收Person的实例？

public class Person
{
  public ILogger Logger { get; set; }
  public static Person FindByName(string name)
  { }
  public static Person FindOrCreateByName(string name)
  { }
  public void DoSomething() { }
}

class Program
{
    static void Main(string[] args)
    {
        using (var container = new WindsorContainer())
        {
            container.Install(FromAssembly.This());
            // Create Person from FindOrCreateBy()
        }
    }

}

将它们转换为实例方法。就是这样。

否则，您需要进入service locator anti-pattern：

public static Person FindByName(string name)
{
     // You're coupling your implementation to how dependencies are resolved,
     // while you don't want this at all, because you won't be able to test your
     // code without configuring the inversion of control container. In other
     // words, it wouldn't be an unit test, but an integration test!
     ILogger logger = Container.Resolve<ILogger>();
}
