- Typically in Spring projects we are using layered approach to build applications.
- Web Layer
- Business Layer
- Data Layer
- Although each layer has different responsibilities, There are few common aspects that apply to all layers
- Such as security, logging, performance etc. This common aspects are called Cross Cutting Concerns
- Aspect Oriented Programming are implementing Cross Cutting Concerns
- We can implement AOP with 2 popular AOP Frameworks:
- Spring AOP: This framework only works with Spring Beans and it is not a complete solution
- AspectJ: This framework is complete AOP solution
- AOP Terminology:
- Advice: The answer that what code to execute. Like Logging, Authentication etc.
- Pointcut: Annotation that identifies method calls to be intercepted. If you are looking for example, you can check out my codes in LoggingAspect.java
- Aspect: Framework that implements AOP
- Annotations:
- @Before: Do something before method is called
- @After: Do something after method is executed irrespective of whether:
- Method executes successfully
- Method throws an exception
- @AfterRunning: Do something only when a method executes successfully
- @AfterThrowing: Do something only when a method throws an exception
