spring aop example

AOP is the abbreviation of aspect oriented programming, which means: face-cutting programming, through the Pre-compilation method and Run-time dynamic agent implementation of the unified maintenance of the program functions of a Technology. AOP is an important part of the spring framework by defining an entry point for an existing program and then cutting into di

Pointcut.java in the Spring download package, the path is SPRING-FRAMEWORK-2.0-M1/SRC/ORG/SPRINGFRAMEWORK/AOP and you can see Pointcut.java. The source code is as follows: pointcut.java************** Package ORG.SPRINGFRAMEWORK.AOP; Public interface Pointcut { Used to qualify a pointcut in a given target class Classfilter Getclassfilter (); A method used to dete

program's run, such as a method call, exception throw, and so on. The Doauditing () method in the previous example is a join point that indicates that the program is adding advice to this place. Pointcut is a collection of join points, which is the set of locations in the program where you need to inject advice to indicate the conditions under which the advice will be triggered. The Org.springframework.aop.Pointcut interface is used to specify notifi

When using spring AOP, it is necessary to determine the annotations on the target method, such as caching, authentication permissions, etc.Custom annotations Packagecom.agent.annotation;ImportJava.lang.annotation.ElementType;Importjava.lang.annotation.Retention;ImportJava.lang.annotation.RetentionPolicy;ImportJava.lang.annotation.Target;Importorg.springframework.stereotype.Component, @Component @retention (

What is AOPAOP-oriented tangent programmingadopt the horizontal extraction mechanism to replace the traditional longitudinal inheritance system repetitive code (performance monitoring, transaction management, security check, cache)Spring AOP uses a pure Java implementation that does not require a dedicated compilation process and ClassLoader to weave the enhanced code into the target class at run time by pr

This article is for Reading Notes. For more information, see spring in Action 2 Chinese edition. Of course, this article is also a boring explanation. Most of the explanations of AOP terms are not intuitive, so I will first copy the explanations in this book, then I add my own explanations, and then add a picture to add some explanations. In this way, I try to clarify these terms so that the subsequent exp

In Spring AOP, there are 3 common concepts, advices, Pointcut, and Advisor, which are explained as follows: Advices: Represents an action before or after a method is executed. Pointcut: means to intercept a method based on the name of the method or the regular expression. Advisor:advice and Pointcut are composed of separate units, and can be passed to the Proxy factory object. We can u
