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
Overview
Aspect-oriented programming (AOP) is an exciting new specification that has the same effect on software development as the more than 10-year-old object-oriented programming (OOP). AOP and OOP are not competing technologies, and in fact
Compared with spring1.x, spring2.x uses ASPECTJ syntax to declare AOP, which makes it more "standard" and more flexible. Still, if you don't know aspectj and intend to use spring2.x's AspectJ AOP, then learn AspectJ, and there's a lot of books.
Adding class Libraries: Aspectjrt.jar and Aspectjweaver.jar
Add an AOP schema.

Write Java classes and use @aspect annotations as notifications
AspectJ supports 5 types of notification annotations:

Take Jdkregexpmethodpointcut as an example to show how to use a static pointcut using a complete example (see routine 4.3 for the complete engineering code). In engineering we define a people class and a slice, and link them to the spring XML
In today's MVC framework, it seems that WEBWORK2 is gradually becoming mainstream, and the combination of webwork2+springframework is becoming more and more popular. This seems to imply that spring's own MVC framework is far worse than WEBWORK2, so
Read a book, the title is "Ascpectj in action", just this section of the project to engage in a paragraph, so there is a little leisure, decided to write something.

Introduction: Dependency Inserts and aspect-oriented programming are complementary technologies, so it's natural to want to combine them together. Follow Adrian Colyer to explore
Java EE JAVA2 Enterprise Edition has played a very important role in the unification of the middleware domain idea. For example, Java EE provides a standard set of programming interfaces for distributed transaction management, directory services,
Note the small example of using annotations to implement Spring AOP.
The first step is to import the associated jar package: Aspectjweaver-1.6.8.jar (provide annotation org.aspectj.lang.annotation.Aspect, etc.), Spring-aop-3.0.4.release.jar

The quote reopened: "OOP is in the ascendant and AOP is starting to emerge again." is AOP a branch of OOP, a complement or a transcendence? ”

Because the spring with the sample from our actual project is very far away, so the official point model layer mode show depends on Appfuse.
But Appfuse's model layer has a total DAO interface, a Daoimpl class, a service interface, a Serviceimpl
The development of Internet has promoted the communication of the whole world, it needs to develop the WEB application that satisfies the requirements of different regions ' language, culture and living habits, therefore, the internationalization of
1. Preface
Aspect oriented Programming (AOP) is a hot topic recently.
ASPECTJ is the implementation of the AOP Java language, and has received extensive attention from Java programmers.
For specific information about ASPECTJ and AOP, find from
In general, we put the transaction in the service layer, using the service's business logic interface Unified Management.
Why not at the DAO layer?
Because it is possible for a service to invoke more than one DAO, the multiple DAO may be
The main focus of AspectJ 5, which is currently in its second milestone version, is to support the new Java language features introduced in Java 5, including annotations and generics. AspectJ 5 also contains new features that are not joined to Java 5
