摘　　要：针对企业面向服务体系架构(SOA)环境中非实时服务的重复请求问题,提出一种基于简单对象访问协议(SOAP)扩展的服务响应缓存策略,并在企业服务总线(ESB)上进行了实现,通过将服务响应缓存起来用于应答一定时间内的相同请求,以提高对于这些请求的响应速度。该策略能同时处理普通SOAP响应和带附件SOAP响应,并对SOAP附件设置了防重复缓存机制。在对两个实际服务的测试中,其服务响应时间与采用缓存策略前相比分别缩短了38%和22%,证明了该缓存策略的有效性。Concerning the repetitive requests to non-real time services in the Service Oriented Architecture（SOA）,the authors proposed a response caching strategy based on the extension of Simple Object Access Protocol（SOAP）and XML-binary Optimized Packaging（XOP）and implemented it in Enterprise Service Bus（ESB）,which cached the service responses for replying the same requests within a certain period of time in order to accelerate the response to these requests.This strategy can be applied to the general SOAP responses and that with attachments,and it also sets a mechanism to prevent the duplicate caching of the same attachments.For the two services been tested,the response time to the same request is shortened by 38% and 22% with the use of the response caching strategy.
