aopalliance-1.0
说明： 在软件业，AOP为Aspect Oriented Programming的缩写，意为：面向切面编程，通过预编译方式和运行期动态代理实现程序功能的统一维护的一种技术。AOP是OOP的延续，是软件开发中的一个热点，也是Spring框架中的一个重要内容，是函数式编程的一种衍生范型。利用AOP可以对业务逻辑的各个部分进行隔离，从而使得业务逻辑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(In the software industry, AOP is the abbreviation of Aspect Oriented Programming, which means: Face-Oriented Programming, a technology to achieve unified maintenance of program functions through pre-compiling and run-time dynamic proxy. AOP is the continuation of OOP, a hotspot in software development, an important content in Spring framework, and a derivative paradigm of functional programming. Using AOP can isolate all parts of business logic, which reduces the coupling between the parts of business logic, improves the reusability of programs, and improves the efficiency of development.)
