. 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. The following is an example of the AOP imple

Aspect (aspect): it is similar to a class, but the focus of the two is different. The class is the abstraction of Object Features, while the aspect is the abstraction of cross-cutting concerns. Joinpoint: the so-called connection point is the intercepted point. In spring, these points are methods, because spring only supports connection points of the method type,

. The entry point can narrow down the connection points of the aspect notification. The entry point defines the "where" use of the Section. The definition of the start point matches one or more connection points to be woven.We usually use clear class and method names, or use regular expressions to define matching class and method name templates to specify these entry points. Some AOP frameworks allow creation of dynamic entry points, You can apply the

This article is a basic knowledge analysis of Spring AOP, which does not involve source code analysis, only includes explanations of important concepts in AOP, analysis, and the use of spring AOP.Spring introduces a simpler yet powerful aspect-oriented programming approach based on XML and ASPECTJ annotations from version 2.0. Before delving into how to use spring for aspect-oriented programming, let's look

Spring AOP The full name of AOP is Aspect Oriented Programming. The purpose of AOP is to separate complex logic and extract commonalities, so that the functions implemented by each part are more specific. For example, in the classic case of Spring AOP implementation, "transaction management", each business class accessing the database may use transaction control to extract its transaction management code from a specific class, put it in a separate pla

functionReturn wrapperfoo = Timeit (foo)Foo ()In this way, a simple timer is ready! We only need to call Foo after the definition of foo, and foo = Timeit (foo), to achieve the purpose of timing, which is the concept of adorners, which looks like Foo was Timeit decorated. In this example, the function enters and exits with timing, which is called a cross plane (Aspect), which is called aspect-oriented prog

There are several concepts in AOP:-Square/Facet (Aspect): A focus of modularity, this focus implementation may be additional crosscutting multiple objects. Transaction management is a good example of crosscutting concerns in the Java EE application. The aspect is implemented with spring's advisor or interceptor.-Connection point/Weaving Point (joinpoint): an explicit point in the execution of a program, suc

Yui3's AOP (Aspect-Oriented Programming), OOP (Object-Oriented Programming), and yui3aop First, put your hands in front of your chest to become a meditation: I went to life, or I was living myself? I didn't come up with the answer. Well, I can read the following. From a semantic perspective, different expressions of the same thing can reflect the different subjective perspectives of people. From a philosophical perspective, we will look at different p

Preface As a classic design paradigm, object-oriented (OOP) is a classic summary for us. Do you still remember the classic summary at the beginning of the line-Everything is an object.Yes. Based on the characteristics of OOP encapsulation, inheritance, and polymorphism, we will naturally follow the modular and componentized thinking to design and develop applications, to achieve easy maintenance, scalability, and high reuse.Since OOP has so many advantages, we often mention what the

The full name of AOP is Aspect-oriented programming, which is the core idea of Aspect-Oriented Programming.AOP is an object-oriented programming language that does not conflict with each other. They are complementary design models.Spring containers do not depend on AOP. The goal is not to provide the latest AOP implementation. It focuses on providing close integration between AOP implementation and springio

Introduction Aspect-Oriented Programming(AOP) has been around for a long time, but has not been favored by the Microsoft. NET development community until recently. Adoption of any new technology often leads to misunderstandings about the technology and its use, and AOP is no exception. To clarify the misunderstanding of AOP, this article and the following code examples will illustrate the actual application of AOP and some common problems that can be

What is AOP? AOP is the abbreviation for Aspect oriented programming. 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. AOP enables the isolation of parts of the business logic, which reduces the coupling between parts of the business logic, improves the reusability of the program, and improves the efficiency of development. For more in

and makes code changes simple and elegant. 2. in future maintenance, it is easy and easy to maintain because the business logic code is stored separately from the common code, and the common code is stored centrally. Aspect-oriented programming AOP technology is to solve this problem is born, the aspect is cross-sectional,6-5 , represents a universal common function, for example, log plane, permission plan
