基于AOP的Java程序性能跟踪系统的设计与实现

he Java language's advantages, free、cross-platform、high efficient development、 make it has been widely useed in all areas of software development. However, Java's system structure determines its low operation efficiency, which limits further expansion of Java. Therefore, it is necessary to optimize Java program's performance. To improve the performance of the program, it depends on the runtime performance data. Without reliable data, if we change the application or environment, it can cause worse results. This paper describes the design and implementation of Java performance tracking system, which can collect Java runtime data, for fine-grained analysis of performance. Meanwhile, in order to reduce code coupling and improve maintainability and scalability, this paper uses AOP (Aspect-Oriented Programming) to strip the tracking functions off the main business functions.
