温莎城堡与静态方法

Question

我有一个由 Simple.Data 支持的类，它具有类似 ActiveRecord 的接口，该类的对象大部分时间都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 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()
        }
    }

}

Answer 1

把它们变成实例方法。就是这样。

否则，您将需要落入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>();
}
