object that is enhanced by the AOP framework, also known as an enhanced object. If the AOP framework is implemented through a runtime proxy, then the object is a Proxied object.3, AOP Proxy: The object created by the AOP framework, simply put, the agent is the enhancement of the target object.4, Weaving (Weaving): Add enhanced processing to the target object, and create an enhanced processing process is to weave in.2, Spring's AOP supportIn AOP progr

The core ideas of spring are IOC and AOP. Recently, learning about AOP has made a further understanding of the study of facets.Spring uses proxy classes to wrap facets and weave them into spring-managed beans. In other words, the proxy class is disguised as the target class, it intercepts the call to the method in the target class, so that the caller calls the target class first to call the Masquerade class, the masked class first executes the slice,

　　For the two issues mentioned at the end of the previous blog http://www.cnblogs.com/cdf-opensource-007/p/6464237.html, you can use the automatic proxy generator provided by spring to resolve. The automatic proxy generator allows us to weave slices into the target object method without using the Proxyfactorybean class to generate proxy objects, and it is possible to weave the facets into multiple proxy pro

called crosscutting concerns.2. Slice (aspect)A class is an abstraction of an object's characteristics, and a facet is an abstraction of a crosscutting concern.3, Connection point (Joinpoint)The point that is intercepted, because spring only supports connection points of the method type, so the connection point in spring refers to the method being intercepted, in fact the connection point can also be a field or a constructor4. Entry point (pointcut)Definition of interception of connection point

, Connection point (Joinpoint)A connection point is a point in the execution of an application that is able to insert a slice, which is exactly the timing of a program's operation, such as when a method is called, when an exception is thrown, or even when a field is modified. Slice code can take advantage of these points (timing) to insert into the normal process of the application and add new behaviors.3. Tangent point (Pointcut)A facet requires only a limited number of connection points to be

regular expressions to define matching classes and methods to specify these pointcuts. Some AOP frameworks allow us to create dynamic pointcuts that can be used more at runtime to determine whether notifications are applied.4. Facets (Aspect)?? Facets are a combination of notifications and pointcuts. Notifications and Pointcuts define the entire content of the slice, what it is , when and where it will function.5. Introduction?? The introduction allows us to add new methods or properties to exi

AOP (Aspect Orient programming), aspect-oriented programming is a complement to object-oriented programming oopsObject-oriented programming uses a static perspective to consider the structure of a program, while aspect-oriented programming is a dynamic consideration of the program's running processThe underlying AOP is implemented using dynamic proxy mode. Two kinds of proxies are used: Dynamic proxy domain cglib dynamic proxy of JDKAOP Programming belongs to:1. Facets (Aspect)Tangent refers to

: the process of adding enhanced processing to a target object and creating an enhanced object (an AOP proxy) is to weave it in. There are two implementations of weaving: compile-time enhancements (such as ASPECTJ) and runtime enhancements (such as Cglib). Spring, like other pure Java AOP frameworks, completes weaving at run time. It is known from the previous introduction that an AOP proxy is actually an object that is dynamically generated by the AO

The following are described separately.1. Pre-notification (front-mounted enhancement)The as implies notification is intended to

verifies at compile time, and the detection exception is handled through the throws statement or the try{}cathch{} statement block. The compiler parses which exceptions are thrown when executing a method or constructor. aspect-oriented programming (Aspect oriented PROGRAMMING-AOP): Facets can be woven at compile time, at run time, at runtime, or at run time. compile time : compile-time weaving is the simplest way. If you have the code for your app, you can use the AOP compiler (for example,
