Objective:In the previous article: [Spring Framework]spring An introduction to AOP basics. We already know how a spring AOP program is developed, and here we will summarize and learn AOP based on ASPECTJ.One, AspectJ's Overview:ASPECTJ is a tangent-oriented framework that extends the Java language. ASPECTJ defines the

AOP (Aspect Orient programming), which is aspect-oriented programming, is a complement to object-oriented programming and is designed to be used in processing systems that are distributed across modules (in different ways)Cross-focus issues in Java in EE applications, AOP is often used to process some system-level services with crosscutting properties, such as transaction management, security full check, cache, object pool management, and more. AOPimplementation of The key is that the AOP framew

AspectJ AspectJ is a very good AOP framework that extends the Java language and defines a set of SOP syntax. Therefore, Java projects that use AspectJ need to use the compiler AJC provided by AspectJ instead of Javac. AspectJ programming is available in two ways, using exte

Then, this article will really begin to explain the situation of AOP. The implementation of AOP through

Aspect-oriented programming (AOP) is a programming paradigm designed to improve modularity by allowing separation of crosscutting concerns. AOP provides an aspect to modularize the point of focus across objects. While many AOP frameworks are now available, there are only two popular frameworks that we want to differentiate here: Spring AOP and AspectJ. This will help you choose the right technology for your

In the Java language, from the way of weaving, there are three ways of weaving: compile-time weaving, class-loading period weaving and running period weaving. Compile-time weaving refers to the use of special compilers in the Java compilation period, weaving slices into Java classes, and class load-time weaving refers to the weaving of slices through a special class loader when the class bytecode is loaded into the JVM, and the run-time weaving is through the cglib tool or the JDK dynamic proxy.

In our previous blog, we brought up the concept of AOP and the implementation of AOP in a specific way. But why do we do this? And how does the pointcut expression come to be understood?In this blog we will learn more about the introduction of the AspectJ framework.1. What is AspectJ?ASPECTJ is a tangent-oriented framework that extends the Java language.
