摘　　要：以WS-Resource工厂模式和EPR的可传递性为基础,提出一种Web服务资源框架(WSRF)服务调度和资源监控的机制。通过建立Proxy Factory服务,在代替客户端创建资源实例,并在进行端点引用传递的过程中成功实现WSRF服务的按需调度和对资源属性的监控。该机制具有调度时机更为合理、调度机制对服务方和客户端透明、资源监控机制不影响客户端操作和接口开放便于系统集成等优点,使得原有基于GT4开发的各种WSRF服务和客户端几乎不需改动就能在该机制下运行。This paper presents a dispatching and resources monitoring mechanism lot Web Services Resource Framework（WSRF） services based on WS-Resource factory pattern and Endpoint Reference（EPR） passing method. A Proxy Factory, service is involved and substituted to create WS-Resource instance for client. In this process and the EPR passing process, on-demand dispatching and resource properties monitoring handlers are successfully inserted. It makes this mechanism more reasonable and transparent to clients or service providers and do not affect the client operations. With few or no need to recoding, most Glohus Toolkit 4（GT4） WSRF services and clients that already existing can be easily integrated into this mechanism.
