Aspects Oriented Programming (AOP) with Spring
Previous Home Next

Aspect-Oriented Programming (AOP) complements Object-Oriented Programming (OOP) by providing another way of thinking about program structure. The key unit of modularity in OOP is the class, whereas in AOP the unit of modularity is the aspect. Aspects enable the modularization of concerns such as transaction management that cut across multiple types and objects.

Aspect-oriented programming breaking down program logic into distinct parts (so-called concerns, cohesive areas of functionality). All programming paradigms support some level of grouping and encapsulation of concerns into separate, independent entities by providing abstractions (e.g., procedures, modules, classes, methods) that can be used for implementing, abstracting, and composing these concerns.

There are various common good examples of aspects like logging, auditing, declarative transactions, security, and caching etc. A cross-cutting concern is a concern that can affect the whole application and should be centralized in one location in code as possible, such as transaction management, authentication, logging, security etc.

AOP is used in the Spring Framework
  1. Provide declarative enterprise services, especially as a replacement for EJB declarative services. The most important such service is declarative transaction management.
  2. Allow users to implement custom aspects, complementing their use of OOP with AOP.

 

Types of AOP advice

Based on the execution strategy of advices, they are some following types as given below.

  1. Before Advice: These advices runs before the execution of join point methods. We can use @Before annotation to mark an advice type as Before advice.

  2. After (finally) Advice: An advice that gets executed after the join point method finishes executing, whether normally or by throwing an exception. We can create after advice using @After annotation.

  3. After Returning Advice: Sometimes we want advice methods to execute only if the join point method executes normally. We can use @AfterReturning annotation to mark a method as after returning advice.

  4. After Throwing Advice: This advice gets executed only when join point method throws exception, we can use it to rollback the transaction declaratively. We use @AfterThrowing annotation for this type of advice.

  5. Around Advice: This is the most important and powerful advice. This advice surrounds the join point method and we can also choose whether to execute the join point method or not. We can write advice code that gets executed before and after the execution of the join point method.

    It is the responsibility of around advice to invoke the join point method and return values if the method is returning something. We use @Around annotation to create around advice methods.
