How to get the value from Custom Annotation in my advice method in Spring AOP?-CodePudding

I have my custom annotation like this:

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface CutomAnnotation{
    
    String value() default "";
}

My Aspect class looks like this:

@Aspect
@Component
public class MyCustomAspect{


@Around("@annotation(com.forceframework.web.handlers.monitoring.MeterRegTimer)")
public Object aroundJoinPoint(ProceedingJoinPoint joinPoint) throws Throwable{
    
    System.out.println("Timer started: " joinPoint.getSignature());
    Object objToReturn=joinPoint.proceed();
    System.out.println("Timer ended: " joinPoint.getSignature());

    return objToReturn;
    }
}

The place I use the annotation in a controller class:

.
.
.
@CustomAnnotation(value="timer")
@GetMapping(value="/test")
public ResponseEntity test(){
}
.
.
.

I would like to know can I access the 'value' passed from my 'CustomAnnotation' in the Around advice method-'aroundJoinPoint' in 'MyCustomAspect'class.

CodePudding user response：

Your advice should be declared as shown below:

@Around("@annotation(customAnnotationArgumentName)")
public Object aroundJoinPoint(ProceedingJoinPoint joinPoint, CustomAnnotation customAnnotationArgumentName) throws Throwable {
// ...
}

See documentation for more info.

    MethodSignature signature = (MethodSignature) joinPoint.getSignature();
    Method method = signature.getMethod();
    CutomAnnotation methodAnnotation = method.getDeclaredAnnotation(CutomAnnotation.class);
