| 摘 要： | 目前基于Sun J2EE架构开发企业级分布式应用系统越来越多,在EJB的组件开发过程中,经常困扰开发和设计人员的是实体Bean的运行效率较低.本文通过深入分析EJB组件开发中实体Bean的工作原理,提出了一种通过避免BMP实体Bean的盲目写操作而提高运行效率的有效算法,并在实际测试中取得了较好的效果.

| Abstract: | More and more enterprise-level distributed application system are developed based on Sun J2EE architecture, but low running performance of Entity Beans often occurred in the process of the developing of EJB (Enterprise JavaBeans) components. Based on deeply analysis to the working mechanism of EntityBean in EJB components, an effective algorithm that can improve the running efficiency by avoiding EntityBean's blindness write operation is suggested in this paper. Practical test shows satisfied results. |
