为什么要有本篇文章
本篇文章主要实现了RTX消息生产者,并且完成了整体的设计方式,之前在设计时消息生产者全局使用单一的生产方式,即一个项目里使用了Email就不能使用SMS,这种设计方法和实际不相符,虽然在性能上是最佳的(采用了单例模型,维护一个生产者,使用策略模式进行生产者的实现,使用工厂模式生产具体生产者),实际项目中,应该是可以自动选择消息生产者的,当然为了程序的性能,我们还必须使用单例模式来生产具体生产者,这种单例,在本程序中,采用了具体类型,具体单例的方法,即Email自己维护单例,SMS自己维护单例,这样,程序即能满足实际的需要,又可以提高自己的性能!
强大的设计
强大的生产者
/// <summary> /// 消息生产者 /// 具体消息生产者是单例,如Email,SMS,Rtx等 /// </summary> public class MessageFactory { /// <summary> /// 消息工厂 /// </summary> public static IMessageManager GetService(MessageType messageType) { switch (messageType) { case MessageType.Email: return EmailMessageManager.Instance; case MessageType.SMS: return SMSMessageManager.Instance; case MessageType.RTX: return RTXMessageManager.Instance; default: throw new NotImplementedException("消息生产者未被识别..."); } } }
