摘　　要：Java动态代理机制的出现,使得Java开发人员不用手工编写代理类,只要简单地指定一组接口及委托类对象,便能动态地获得代理类。代理类会负责将所有的方法调用分派到委托对象上反射执行,在分派执行的过程中,开发人员还可以按需调整委托类对象及其功能,这是一套非常灵活有弹性的代理框架。针对此框架的优点,把它引入到考试系统的应用中,使得系统的维护和扩展增强,而且减少了编程工作量。The emergence of Java dynamic proxy mechanism makes the Java developers dynamically obtain the proxy class by specifying a set of interface and delegate class object without manually writing the proxy class. The proxy class will be responsible for assigning all the method to the delegate object for reflection execution. During the assignment, the developers can also adjust the delegate class object and its fimction as needed, which is a very flexible and resilient agent framework. The introduction of this framework into the？examination system can enhance？the maintenance and expansion of system, and reduce the workload ofprogramming.
