Spring AOP AspectJ @AfterReturning Annotation Example

In this Spring AOP example, we will learn to use AspectJ @AfterReturning annotation in Spring-based applications. After returning advice methods annotated with @AfterReturning that will execute after a join point completes normally, meaning that the target method returns normally without throwing an exception.

In this example, We will create a simple spring boot application, add logging aspect and then invoke aspect methods based on pointcuts information passed in a @AfterReturning annotation.

AspectJ @AfterReturning Annotation Usage

Below snippet shows usage of @AfterReturning annotation:

@Aspect
@Component
public class LoggingAspect {

    private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());

    @AfterReturning("execution(* net.guides.springboot2.springaop.service.EmployeeService.*(..))")
    public void logAfterReturningAllMethods() throws Throwable {
        LOGGER.debug("****LoggingAspect.logAfterReturningAllMethods() ");
    }

    @AfterReturning(pointcut = "execution(* net.guides.springboot2.springaop.service.EmployeeService.getEmployeeById(..))", returning = "retVal")
    public void logAfterReturningGetEmployee(Object retVal) throws Throwable {
        LOGGER.debug("****LoggingAspect.logAfterReturningGetEmployee() ");
    }

    @AfterReturning("execution(* net.guides.springboot2.springaop.service.EmployeeService.addEmployee(..))")
    public void logAfterReturningAddEmployee() throws Throwable {
        LOGGER.debug("****LoggingAspect.logAfterReturningAddEmployee() ");
    }
}
