Programming with spring-oriented facets1. IntroductionAOP is a complement to OOP and provides another way of thinking about the structure of the program.The modular key unit of OOP is the class.AOP is the aspect facet.AOP divides the logic of the program into separate blocks (called concern center of gravity, Focus point).AOP is used to increase the modularity of the cross-cutting center of gravity (cross-cutting concerns).A cross-cutting concern is a

Every year as Christmas, Father ' s Day and dad's birthday roll around, the usual list of possible presents immediately come S to mind. Does He need a new razor? Anything starting to look a little ratty in the wardrobe? How about in the garage, CO2 laser engraver tool shed or basemen

Programming AOP for Facets is a major feature of springAspect Facets: A (Enhanced) class that encapsulates the functionality of a common featureAdvice by: A method of encapsulating enhancements in a slice class.PointCut: A pointcut, is the concept of a collection that expresses using a regular expressionBefore and after all the methods of all core business objects (transactional AOP typical applications)Joinpoint: Connection point, where the program needs to join advice, and the ponitcut being e

to the map. The reference of the map object is obtained through the BusinessUnitService object. point cut and advice constitute the so-called "Aspect (Aspect )"To read data in the storage media, the OOP method uses a DAO class. in AOP, you define a point cut and an advice in the scope class to read data. the AOP framework injects code in the form of advice, which can be executed or compiled.All in all, whe

Software 152 Liu AnminAOP is the continuation of OOP and is the abbreviation for Aspect oriented programming, meaning aspect-oriented programming. AOP is actually a continuation of the GOF design pattern, and the design pattern pursues the decoupling between the caller and the callee, and AOP can be said to be an implementation of this goal.The implementation of AOP technology, mainly divided into two major

1 AOPOverviewAOP (aspect-oriented programming, aspect-oriented programming ): is a new methodology for traditional OOP ( Object-oriented programming, Object-oriented programming ) complements. The main object of the AOP programming operation is the tangent plane (aspect), while the facets are modular crosscutting concerns .When you apply AOP programming, you st

Part 4 and 5th of this series discuss how to use Javassist to make local changes to a binary class. This time you will learn to use the framework in a more powerful way to take advantage of Javassist's support for finding all specific methods or fields in bytecode. For the Javassist feature, this feature is at least as important as its ability to specify bytecode in a similar way to source code. Support for the Select substitution operation also helps make javasssist a great tool for adding

@aspect of Spring AOP Transferred from: http://blog.csdn.net/tanghw/article/details/3862987Starting with Spring 2.0, you can implement AOP using schema-and @aspectj-based approaches, a simple example of how to implement AOP in spring in a @aspectj way. Since @aspect is annotation-based, it is required to support more than 5.0 versions of the JDK for annotations.Environmental requirements: 1. Web Applicatio

Aspect can clear code pollution? Logging with the Aspectwerkz framework is the first step Introduction: Aspect-oriented programming (aspect-oriented PROGRAMMING,AOP) allows code to be kept clean by separating functionality that works within the application scope rather than in a class or package. Logging is a common example of this functionality. Can AOP help wi

1. What I know about AOPAt first glance, there is a lot of terminology, and there is a name for the wind, for the aspect programming, is a useful complement of OOP and so on. Let you at a loss, thought: Not many people and I said that AOP is more difficult. When I look inside, I can only find out: He is a simple and unpretentious application on Java basis, including the IOC (see the Spring IOC (dependency injection, inversion of control) conceptual un

PHP aspect-oriented programming component. We use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantly complicated, the more we call the methods in the model in the controller, the more we use the MVC framework, such as CI, YII, and cakePHP. one of the reasons is that the code can be easily maintained. However, when the business logic is constantl

Detailed description of the Python decorator mode and Aspect-Oriented Programming This article mainly introduces the Python decorator mode and Specific Aspect-oriented programming. In summary, the function of the decorator is to add additional functions for existing objects, this article details all aspects of the decorative device model, and then introduces the knowledge of cross-section programming. For m

and elegant. In future maintenance, because the business logic code is separated from the common code, and the common code is stored in a centralized manner, maintenance becomes simple and easy. The Aspect-Oriented Programming AOP technology was born to solve this problem. The Aspect-oriented programming is a horizontal aspect, as shown in 6-5, which represents

And can decide whether this method executes, when to execute.4. Facets ( Aspect):The combin

these infrastructure services, and with this problem, a lightweight Java solution emerges, which is the spring framework. Spring was born to simplify enterprise-level system development, and the spring Framework provides a simple, effective solution for Java EE to apply common problems, using spring, you can use simple Pojo (Plain old Java Object) To implement features that were previously only EJB-enabled. This will not only simplify server-side development, but any Java system development ca

as either a enabling technology that allows Spring to provide declarative transaction manage ment without EJB; Or use the full power of the Spring AOP framework to implement custom aspects.If you is interested only in generic declarative services or other pre-packaged declarative middleware services such as P Ooling, you don ' t need to work directly with Spring AOP, and can skip the most of the this chapter.1.1. AOP ConceptsLet us begin by defining some central AOP concepts. These terms is not

concise and elegant. In future maintenance, because business logic code is stored separately from common code, and common code is centrally stored, it makes maintenance easier and easier. Aspect-oriented programming AOP technology is to solve this problem is born, the section is cross-section, as shown in Figure 6-5, represents a universal common function, for example, log section, permission section and transaction plane.
