Understanding of Aspect-oriented programming (AOP) and Aspect-oriented programming (aop) When writing traditional business logic processing code, we usually habitually do several things: logging, Transaction Control and Permission control, and then write the core business logic processing code. After writing the code, you can't help but find that only a few lines of code are available for core business logi

Spring entry (4) [Aspect-Oriented Programming], spring entry-oriented Aspect-Oriented Operations such as logs and transactions are often used in the development process. If these operations need to be written in the Business Code, it will be quite troublesome. In this case, we will use Aspect-oriented programming (AOP ), as a programming idea, AOP has different e

Gary Pollice, Professor of Practice, Worcester Institute of Technology May 15, 2006 A review of the concept of AOP If you are unfamiliar with AOP, there are a lot of introductory articles about it, including the articles I published in February 2004. 2 A lot, maybe not all, introduction to AOP use the log as an example to illustrate aspects of the concept. (logs are something that many people understand, and it's a good example of how AOP can be used.) ) concern is crosscutting. That is to say,

As the first part of this series that introduces aspect-oriented programming in the Spring Framework (aspect-oriented PROGRAMMING,AOP), this article describes the basics of enabling you to use aspect-oriented features in spring for rapid development.

1. Aspect Library As you all know, the core of the various AOP tools is the declaration of Pointcuts (Pointcut) and notifications (advice). The pointcut describes where the execution of the main program meets the execution of the aspect, which is the location of the crosscutting; The notification describes what action should be taken when a matching pointcut is encountered during program execution. Suppose

The AOP method has many advantages. Fir

Overview Aspect-oriented programming (AOP) is an exciting new specification that has the same effect on software development as the more than 10-year-old object-oriented programming (OOP). AOP and OOP are not competing technologies, and in fact they complement each other very harmoniously. Object-oriented programming is useful for modeling common object hierarchies. The disadvantage of this is that it deals with common situations across multiple unre

AOP is also called aspect-oriented programming, the "notice" is the specific aspect of the implementation, divided into before (forward notice), after (post notice), around (surround notice), with spring students must be very familiar with it, and in JS, AOP is a serious neglected technical points. However, the use of AOP can effectively improve the JS code logic, such as the front-end framework dojo and Yu

That is, by annotating the @aspect to turn a plain Java class into a slice bean and then enhance the other @component component Java class To use the annotation aspectj, you need to go to the environment configuration (URI configuration of XML namespace of the schema, installation of Jar package) 1.
