In the first glimpse of AspectJ, we mentioned that ASPECTJ provides three new constructs for Java, pointcut,advice and Inter-type Declaration (ITD), And we've introduced a simple demo of how to use pointcut and advice. This article will introduce what Inter-type declaration is, what can be done, and finally, a demo will show how to use it. The following article will mainly use ITD to represent Inter-type declaration. The demo code in this article can be found in GitHub

classes.AOP extracts the aspect of the business processing process. It faces a certain step or stage in the processing process, low coupling isolation between various parts in the logical process is achieved. It is oriented to the verb field and focuses on horizontal. A segment or aspect in a logical process, such as log management and permission management. It focuses mostly on software systems. It is not

I just hope that this article will be used as a brick for everyone to think about and supplement and improve it together, so that our test case design level will continue to improve. Body I.

AOP (plane-oriented programming)In the software industry, AOP is the abbreviation for Aspect oriented programming, which means: face-cutting programming, through the pre-compilation method and runtime dynamic agent to implement the unified maintenance of the program functions of a technology. AOP is a continuation of OOP, a hotspot in software development, an important content in the spring framework, and a derivative model of functional programming.

Reprinted from: http://www.cnblogs.com/sunwke/articles/2568875.htmlThere is a lot of information on the Internet, but most of it starts with explaining the AspectJ grammar, then explains how to apply the AspectJ, how to separate different aspects of the software development process (Aspect)--log,session,authentication and AspectJ. Authorization,transaction, wait.The first contact with AspectJ readers to see this material (or grammar manual), will feel

Aspect-oriented programming (AOP) is a promising new technology, but the adoption of new technologies can be risky (and, of course, there is a risk of not adopting new technologies). As with all new technologies, it is usually best to follow a path that can manage risk. If you use AOP to execute policies and tests, you get the benefit of mitigating risk from AOP. Because the aspect does not go into producti

Use the AOP method in the SpringBoot project, springbootaop This article describes how to use aop in the SpringBoot project. The details are as follows: 1. Overview Implementing General logic with AOP technology can greatly simplify programming, such as signature verification and authentication. Spring declarative transactions are also implemented through the AOP technology. Code reference example project https://github.com/qihaiyan/springcamp/tree/master/spring-aop Spring's AOP technology has f

Insert a system service (such as Logging and Security) unrelated to the business logic in a service process. This logic is called Cross-cutting concerns, the Cross-cutting concerns is designed as an object. This special object is called Aspect ), aspect-oriented programming focuses on Aspect design and Weave ). AOP and OOP do not conflict with each other. They ar

I. What is AOP? AOP(Aspect-Oriented Programming, Aspect-Oriented Programming) can be said to be a supplement and improvement of OOP (object-oriented programing, object-oriented programming. Oop introduces concepts such as encapsulation, inheritance, and Polymorphism to establish an object hierarchy to simulate a set of public behaviors. When we need to introduce public behavior to scattered objects, oop se

property value can be null: @media (color:4) {} @media (color) {} Note, of course, that there is a difference between a property value and a condition that does not have a property value, so the above two rules are not equivalent. CSS rules for multiple media types can be separated by commas: 1 2 3 @media handheld and (min-width:360px), screen and (min-width:480px) { body{font-size:large;} } 1 2 3 @media screen and (min-width:800px), print and (m

Cainiao has a basic understanding of spring aop. And applications, springaop The first time I wrote a blog. I am a cainiao. Correct the error. I posted this blog to organize my learning process. And some ideas. Let's start with the text below: (these things are taken from many blogs and summarized by myself. Please advise if there is anything wrong .) Oop is a vertical programming from top to bottom, and aop is a horizontal cutting. OOP allows you to define the relationship from top to bottom, b

.。There are two ways to provide crosscutting concerns, a traditional OOP approach, and a service that provides the same class as the implementation of the straight-cut focus. The other is the latest AOP approach, which provides a aspect aspect (called Advisor Advisor in Spring AOP) to provide services.The OOP approach is that the business class uses object references and uses "delegation" to invoke methods

Spring learning journey (6) working principles of Spring AOP: springaop AOP (Aspect-Oriented Programming) is one of the key technologies provided by Spring. Based on IoC, AOP is an effective supplement to OOP (Object-Oriented Programming, object-oriented Programming. Using a "cross-cutting" technique, you can segment the encapsulated objects and encapsulate the public behaviors that affect multiple classes into a reusable module, and name it

the specified class. Interaction process between the AOP framework and the original business system:When you enable AOP, the AOP framework is woven and loaded to the original Business System Based on the configuration information.After the business system is started, AOP no longer controls it, and the user interaction will still be performed in the original business system. Note: Due to the introduction of AOP, the system startup process will take a little longer to start the business syste

CanvasscalerThis component is responsible for screen adaptation. The UI system uses Recttransform to calculate the location and size of the UI, but that is not enough. How can I make the UI of a design fit different resolutions, aspect ratios, and DPI? This component gives the following 3 adaptation meth

Background:I need to add a log record to each controller in a Springboot project to record some information about the request.The code looks like this:Logger.info (Request.getrequesturl ());Sort of.The code is not difficult, but due to the number of controllers, it is also hard work. So I thought of using spring AOP to solve this problem.First, add SPRINGAOP dependencies to the POM: Dependency > groupId >org.springframework.bootgroupId> Artifactid>spring-boot-starter-aopartifact

approach infinity. Aspect refers to the orientation of the terrain slope. The slope direction is used to identify the downhill direction with the highest change rate from each pixel to its adjacent pixel. The slope direction can be considered as the slope direction. The aspect direction is an angle, which will be measured clockwise. The angle ranges from 0 (East) to 360 (still east), that is, the complete
