摘要
讨论一种J2EE设计模式Session Facade在分布式系统开发设计中的使用,进一步针对分布式系统并行处理的复杂性,结合Singleton模式提出对Session Facade的一种改进方法。通过设计模式的改进可以显著提高某一个领域内系统开发设计的效率,能够有效增强系统的安全性、数据完整性、性能、可维护性和可扩展性。
Design pattern is the elegant solution to common problems in software design. The application of a type of J2EE design pattern- Session Facade is discussed. Combined with Singleton,a method to improve Session Facade for the complexity of parallel programming is put forward. The efficiency of developing and designing a system of a specified domain can be improved remarkably by design pattern, therefore it can enhance numerous aspects of the system, including security, data integrity,manageability,and scalability.
