How to implement the introduction of Notification in aspect-oriented programming of sping

This article mainly introduces "how to introduce notification in sping-oriented programming". In daily operation, I believe many people have doubts about how to introduce notification in sping-oriented programming. Xiaobian consulted various materials and sorted out simple and easy operation methods. I hope to help you answer the doubts of "how to introduce notification in sping-oriented programming"! Next, please follow the small series to learn together!

The purpose of introducing notifications is to introduce the notifications I want at any connection point, such as the results of the previous four notification cases:

Pre-notification is invoked Post-notification is invoked is pre-notification is invoked is invoked

You can see that notifications are cut in the sayHello() and sayBye() methods of the proxied Test1Service (these two join points); but now I only want to cut notifications in the sayHello() method (this one join point). This requires the use of import notifications, which are actually configured in the configuration file. (I'm now asking for wrap-around notifications only to cut into the sayHello() method)

Modify the configuration file beans.xml of the previous example:

sayHello

com.hubin.aop.TestServiceInter

com.hubin.aop.TestServiceInter2

myMethodBeforeAdvice

myMethodAfterAdvice

annotationAdvice

myMethodThrowsAdvice

Run Results:

Advance notification is invoked

Before invoking surround notification

Hi King sledgehammer

After invoking the wrap notification

Postnotification is invoked

Advance notification is invoked

bye king sledgehammer

Post-notification is called here, and the study of "how to introduce notification in aspect-oriented programming" is over, hoping to solve everyone's doubts. Theory and practice can better match to help you learn, go and try it!
