Basically, think about AOP as an interceptor for method calls, where you can add extra functionality.
Spring AOP is one of the key components of Spring Framework.
So you can use AOP as a profiler, where you can check where are the bottlenecks of your application.
If you are concern if introducing of Spring AOP decrease performance, as you are adding overhead to execution of all your service calls, check this blog post.
Here you will see how to add logging of method calls with Spring.
On every call you can log method name, method arguments, returned object, as well as method execution time.
Aspect Oriented Programming allows you to “define cross-cutting concerns that can be applied across separate, very different, object models”.
Add support for spring-aop and aspectj If you are using maven, and not using spring-aop already, just add this two new dependencies. Define your aspect and pointcuts There are two ways two define aspects : With @Aspect annotation, or in Spring`s file. You can check Spring’s AOP documentation which Joint Point, Advice, Pointcuts, etc. For example if you want to log what method is returning, use @After Returnung Advice: If you want to dynamically enable/disable logging, one way this can be done is introducing new flag in Logging Aspect.
It is very easy to start with, and can be used for getting complicated things done very easy.
For example, Spring Transactional Management is made possible using Spring AOP.
