| 摘 要： | 针对采用多层框架思想开发的系统在EJB性能上的不足,从影响EJB性能的关键因素初始化、查找JNDI和远程调用等方面分析了EJB系统的性能瓶颈.对比目前已有优化策略的缺陷,从使用数据库存储过程、优化JDBC层、减少数据库操作、缓存的使用以及Session Facade、Value Object设计模式等方面提出了改进的优化策略,综合应用各项策略实现了一个高效且性能优化的第三方物流系统.构建的第三方物流系统具有良好的可扩展性和可复用性,使J2EE/EJB多层体系结构更能适应大型企业应用的需求.

| Abstract: | According to the shortage of EJB performance in using multilayer frame system,the performance of EJB system bottlenecks was analyzed from the key factors,such as initialization,JNDI lookup and remote call.Contrast to the shortage of existing optimization strategy,the improved optimization strategy was pointed out from database storage process using,optimization JDBC layer,database operation reducing,the cache and Session Facade,Value Object design patterns,the integrated application strategy,a high efficient and performance optimization of third-party logistics system has been realized,which has good expansibility and reusability,and it adjusts the J2EE/EJB multilayer architecture to large enterprise application easier. |
