摘要
提出了一个基于消息中间件(MOM)的异步可靠Web服务模型,该模型分为服务器端和客户端两大部分,支持同步和异步调用,解决了Web服务调用中可能会出现的异常问题,如服务短暂停止和网络出现故障等。对该模型进行了分析,然后对该模型的客户端和服务器端进行了设计实现。最后该模型通过消息持久化、消息队列和消息状态以及优先级管理和消息保证送达等机制保证了消息传输的可靠性,提高了Web服务的服务质量。
Put forward a supplying asynchronous and reliable WS middleware system called MQ4WS, which consists of MQ4WS client and MQ4WS server, and supports for synchronous and asynchronous invocation, in order to solve problems happening in web services invocation, such as service temporarily unavailable, network connection failure and so on. Then analyze the model, design and implement client and server ofthe model, lastly design and implement its reliability, with message persistence, message queue, message state, priority management mechanism and guaranteed delivery, accordingly improve QoS of web services.
