Spring.Net:注入ApplicationContext / ObjectFactory本身

Question

有没有办法将当前正在执行的IObjectFactory或ApplicationContext作为依赖项传递给对象？例如

  <object id="SpringActionInvoker" type="xxx.SpringActionInvoker, xxx">
    <constructor-arg ref="reference_to_the_ApplicationContext_or_ObjectFactor_that_is_executing" />
  </object>

我想将它用于将被注入控制器的Asp.Net MVC ControllerActionInvoker的Spring.Net实现。

public class SpringActionInvoker : ControllerActionInvoker
{
    private IObjectFactory objectFactory;

    public SpringActionInvoker(IObjectFactory objectFactory)
    {
        this.objectFactory = objectFactory;
    }

    protected override FilterInfo GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
    {
        //use objectFactory to inject dependencies into filters
    }
}

Answer 1

只要让你的类实现IApplicationContextAware，就可以自动注入当前的IApplicationContext。

Answer 2

这样如何：

<object id="SpringActionInvoker" type="xxx.SpringActionInvoker, xxx" />

然后：

public class SpringActionInvoker : ControllerActionInvoker
{
    protected override FilterInfo GetFilters(ControllerContext controllerContext, ActionDescriptor actionDescriptor)
    {
        IObjectFactory objectFactory = ContextRegistry.GetContext();
        //use objectFactory to inject dependencies into filters
    }
}
