摘　　要：服务缓存有利于提高面向服务的体系结构的系统性能和安全性,其模式和服务依赖模式紧密相关.通过分析OSGi服务缓存模式存在的不足,在改进OSGi服务依赖模式的基础上,提出了一种基于服务依赖图的动态服务缓存模式及其自动管理方法,并给出了具体实现方案,包括服务缓存的替换算法,最后提出了服务缓存效率的评价指标.Service-Oriented Architecture often integrates service cache in orderto decrease complexity and to improve system performance and security. Service cache model is great influenced by service dependency model. Based on a revised service dependency model of OSGi platform, a service cache model and related dynamic automatic management approach, as well as the implementation, are proposed. A services replacement algorithm is introduced to replace cached services on-demand. The paper also discusses how to evaluate the service cache.
