这让我对许多配置感到困惑。我一直在阅读文档,我只是不明白。这是我的注册码:
ForRequestedType<SimpleWorkItemProcessor>().TheDefault.Is.OfConcreteType<SimpleWorkItemProcessor>();
ForRequestedType<WorkItemRetryProcessor>().TheDefault.Is.OfConcreteType<WorkItemRetryProcessor>()
.CtorDependency<IWorkItemProcessor>().Is(x => x.OfConcreteType<SimpleWorkItemProcessor>())
.WithCtorArg("busyDelay").EqualTo(TimeSpan.FromMilliseconds(20))
.WithCtorArg("overallTimeout").EqualTo(TimeSpan.FromSeconds(60));
ForRequestedType<WorkItemQueue>().TheDefault.Is.OfConcreteType<WorkItemQueue>()
.CtorDependency<IWorkItemProcessor>().Is(x => x.OfConcreteType<WorkItemRetryProcessor>());
实际上,它说没有IWorkItemProcessor的默认实例(这是正确的)。将最后一行切换为:
ForRequestedType<IWorkItemProcessor>().TheDefault.Is.OfConcreteType<WorkItemQueue>()
.CtorDependency<IWorkItemProcessor>().Is(x => x.OfConcreteType<WorkItemRetryProcessor>());
...造成堆栈溢出异常。
如何将实现接口的类链接在一起,并在构造函数中接受相同的接口?
答案 0 :(得分:0)
这有效,但我无法解释原因。据我所知,第一个版本应该也可以正常工作。
ForRequestedType<SimpleWorkItemProcessor>().TheDefault.Is.OfConcreteType<SimpleWorkItemProcessor>();
var retryProcessor = ForRequestedType<WorkItemRetryProcessor>().TheDefault.Is.OfConcreteType<WorkItemRetryProcessor>()
.CtorDependency<IWorkItemProcessor>().Is(x => x.OfConcreteType<SimpleWorkItemProcessor>())
.CtorDependency<TimeSpan>("busyDelay").Is(x => x.Object(TimeSpan.FromMilliseconds(20)))
.CtorDependency<TimeSpan>("overallTimeout").Is(x => x.Object(TimeSpan.FromSeconds(60)));
ForRequestedType<IWorkItemProcessor>().TheDefault.Is.OfConcreteType<WorkItemQueue>()
.CtorDependency<IWorkItemProcessor>("workItemProcessor").Is(x => x.Instance(retryProcessor));
