Description

AOP代理框架的实现方法、存储介质、电子设备及系统 技术领域
本发明涉及AOP代理领域，具体涉及一种AOP代理框架的实现方法、存储介质、电子设备及系统。
背景技术
AOP(Aspect Orient Programming，面向切面编程)是作为面向对象编程的一种补充，广泛应用于处理一些具有横切性质的系统级服务，如事务管理、安全检查、缓存、对象池管理等。利用AOP可以对业务类(业务类包括构造器和业务方法，业务方法包括静态方法和动态方法)的各个业务项目进行拦截，从而使得业务类的各部分之间的耦合度降低，提高程序的可重用性，同时提高了开发的效率。AOP实现的关键就在于AOP框架自动创建的AOP代理类(即拦截器)，AOP代理类可分为静态代理和动态代理两大类：
静态代理是指使用AOP框架提供的命令进行编译，从而在编译阶段就共同生成AOP代理类和业务类，因此也称为编译时增强；
动态代理则是在运行时借助于JDK(Java语言的软件开发工具包)动态代理、CGLIB(Code Generation Library，一个Code生成类库)等在内存中“临时”共同生成AOP代理类和业务类，因此也被称为运行时增强。
在Java语言领域，成熟且功能强大的AOP实现有AspectJ(一个面向切面的框架)和Spring AOP，它们都提供了整套AOP机制的实现。但是AspectJ和Spring AOP分别存在以下缺陷：
AspectJ采用编译时增强的方式为业务应用生成AOP代理类，由于AOP代理类是在编译时生成的，因此若需要修改AOP代理类的拦截功能，则必须重新编译业务类以应用新的AOP代理类；重新编译业务类的操作流程比较复杂，灵活性较差。
Spring AOP采用运行时增强的方式为业务应用生成AOP代理类，即Spring AOP生成的AOP代理类的逻辑与业务逻辑位于同一个应用中，因此若需要修改AOP代理类的拦截功能，也需要重新编译业务类，即操作流程同样比较复杂，灵活性较差。
