Spring AOP: @annotation(annotation)

if you have the following Spring Bean:

@Component
public class foo {

    @com.pkg.Bar      
    void fooMe() {
    }
}

Then the following Advice:

@Around("@annotation(com.pkg.Bar)")

Will invoke the interceptor around fooMe (or any other Spring bean method annotated with @Bar)

The @Transactional annotation is a good example

You would have a parameter named annotation, of the appropriate type. It's called bound annotation, see this excerpt from the Spring AOP documentation:

The following example shows how you could match the execution of methods annotated with an @Auditable annotation, and extract the audit code.

First the definition of the @Auditable annotation:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Auditable {
    AuditCode value();
}

And then the advice that matches the execution of @Auditable methods:

@Before("com.xyz.lib.Pointcuts.anyPublicMethod() && @annotation(auditable)")
public void audit(Auditable auditable) {
    AuditCode code = auditable.value();
    // ...
}
