Introduction to Spring Boot AOP @AfterReturning
Spring Boot is a popular Java development framework that provides many features to ease the application development process. Among them, AOP (Aspect-Oriented Programming) is one of the important functions of Spring Boot. AOP allows developers to reuse cross-cutting concerns by inserting aspects into the code, making applications more modular and maintainable.
In Spring Boot AOP, @AfterReturningis an advice type that represents the aspect logic to be executed after the target method executes successfully. This article will explain @AfterReturningthe usage in detail, provide a complete example and code, and finally give the running results and summary.
Explaining @AfterReturning
@AfterReturningAnnotations can be used to define an aspect that executes some logic after the target method returns successfully. It has the following important properties:
value: It is used to specify the pointcut expression, indicating which methods will be intercepted and executed@AfterReturning.pointcut:valueThe same function as the attribute, used to specify the pointcut expression, but it allows to be shared and reused.argNames: An optional attribute that specifies the names of the target method parameters so that@AfterReturningthey can be referenced in the logic of .
When the target method returns successfully, @AfterReturningthe decorated method will be executed. This method can access the target party
