| 摘 要： | 在OSGi服务平台中,服务的注销会使和该服务相关联的ServiceReference引用和服务引用过时,过时的ServiceReference引用和服务引用会带来许多问题.但服务什么时候被注销,无法预先知道,且无普遍实用的判定ServiceReference引用和服务引用是否过时的算法.本文通过对OSGi服务平台核心事件的产生和投递过程深入细致的分析,提出了判定ServiceReference引用和服务引用是否过时的方案.

| Abstract: | Unregistration of OSGi services will make some ServiceReference reference and service reference stale, which are associated with it. These stale references will bring a lot of questions. But have no way to know what time the service will be unregistered in advance, and have no arithmetic which can judge whether the ServieeReference reference and service reference is stale. Based on the analysis of generation and the process to be delivered of the OSGi core event, this article puts forward a way which is used to judge whether the ServiceReference reference and service reference is stale. |
