摘　　要：在分析J2EE架构和系统功能的基础上,围绕高效、复用和安全等特性,研究了访问数据库技术的优化、EJB和Java-Bean的设计策略、Struts调用EJB的全过程及Junit测试技术,并提出用回压技术、二项分布、正则表达式、实时监控等来解决考试系统关键环节的方案,论述了考试系统的一种优秀设计思想和实现方法。充分体现了Java2企业版分布式计算平台的优越性。On the foundation of analyzing system function and J2EE construction, around the characteristic of high efficiency, reuse and safety, the performance optimization of database access, the design patterns of EJB and JavaBean, the whole process of struts transferring EJB and the test technique of Junit are studied, and using push-back technique, binomial distribution, Regular Expression and control in real time to solve the key problem of the exam system is put forward, the best design though and realization method of the exam system are discussed. The advantage of J2EE distributed compute platform is shown adequately.
