First, the problem description and the reason.An error occurred when implementing AOP using aspect annotations at:: 0 can ' t find referenced pointcut XXX. I thought the annotations were wrong, and the result was that the two jar packages with the Aspectjweaver.jar and Aspectjrt.jar in Spring2.5 did not match JDK1.7.Org.springframework.beans.factory.BeanCreationException:Error creating Bean with the name ' U ' defined in file [d:\ accelerated Data \3.

JDK Dynamic Agent public static Spring-oriented tangent programming 1. Spring aspect-oriented programming introduction Spring provides 2 proxy modes, one is the JDK proxy and the other Cglib proxy 1. If the target object implements several interfaces, spring uses the JDK's Java.lang.reflect.Pr

inside the class, and spring cannot intercept the method call.That's one step further, and spring provides us with AOP, aspect-oriented functionality. His principle and the principle of asynchronous annotations are similar:When spring starts the container, it scans the class defined by the slice. When these classes are injected, the surrogate class is injected, and when you call these methods, it is essentially the proxy class that is called.By execu

I. Basic CONCEPTS ASPECTJ is a Java based implementation for cutting-plane programming. It adds a new concept of join point to Java, but it's just the name of a Java concept that exists. It adds a little new structure to the Java language: pointcuts (pointcut), Notifications (Advice), type declarations (Inter-type declaration), and Aspects (Aspect). Pointcuts and notifications dynamically affect program processes, and the declarations between types a

So far aspect oriented programming has been well known to developers, whose shorthand AOP is translated into aspect-oriented programming (also known as facet programming). It originated in the 90 's Xerox PARC Laboratory programming paradigm. Known as the continuation of OOP, OOP focuses on the domain problems of the business process, forming domain objects and better describing the natural domain. While AO
