摘要： 大规模的商业多媒体信息发布系统因资源及终端数量庞大,会导致系统性能低下。为此,提出一种能优化系统数据存取操作的数据持久层设计方案。研究并分析多媒体信息发布系统的特征,选择Hibernate框架设计系统持久层,总结Hibernate框架在该类系统中合理并高效使用的方法,针对基于Web的多媒体信息发布系统,给出可以使用Servlet过滤器来管理Hibernate的Session缓存,以延长Session对象的生命周期,减少系统对Session对象的查找,并能较为充分地利用Session对象中的缓存数据。实验结果表明,综合上述多种优化方法,可大幅减少多媒体信息发布系统的资源消耗,有效提高系统的整体性能。

Abstract: For large-scale commercial Multimedia Information Publishing System(MPS) contains huge number of resources and terminals,that can lead to low performance of the system,this paper puts forward a design plan of data persistence layer to optimize the system data access operation.Based on the research and analysis of the characteristics of MPS,it chooses the Hibernate framework as the system data persistence design,summarizes and analyzes the general methods of how to use Hibernate properly in MPS,and puts forward that web-based MPS can use the servlet filters to manage the Hibernate session,which can prolong the life cycle of the session object and reduces the system consumption of the session object,and makes full use of the cached data in the session object.Experimental results show that the integrated optimization method mentioned above,can greatly reduce the resource consumption of MPS system and improves the overall performance of the system effectively.
