异步调用机制在基于Web Service的GIS中的应用研究

Applications of Asynchronous Invocation Mechanism to GIS Based on Web Service

将异步调用机制应用于基于WebService的地理信息系统(GIS)中,从而可及时释放闲置的线程资源,以缓解同步调用机制存在的线程阻塞问题。在此基础上,实验仿真结果表明,相同条件下异步调用GISWeb服务方式可改善系统的线程并发处理能力,提高系统请求处理的效率。

Asynchronous invocation mechanism to GIS based on web service are applied. It will release thread resources in time to overcome the weakness of thread blocking in synchronous invocation. Experimental results indicate that asynchronous invocation of GIS web service will improve thread concurrent handling abilities and request processing efficiency under the same condition.
