| 摘 要： | 面向插件的应用框架具有易于复用和动态扩展的特性。为了实现框架中插件的动态加载与替换,可以采用Service Locator模式解除插件接口调用者与插件实例间的耦合。通过一个实例介绍了如何改进Service Locator模式使之更好地管理大量的细粒度短生命周期的插件对象,并展示了采用改进的Service Locator模式来设计面向插件的应用框架的方法。

| Abstract: | Plug-in oriented application framework can be easily reused and dynamically extended.To achieve dynamic loading and substitution of plug-in in application framework,Service Locator pattern is introduced to decouple clients from the implementation of plug-ins.A case study illustrates how to introduce a revised Service Locator pattern,which works better with large amount of fine-grained short-lived plug-in objects,to a plug-in oriented application framework design. |
