How to write a pointcut for all methods of class annotated by @Service and having return type void

Question

I am trying to write a point cut for all void methods of classes that are annotated by @Service.

At first I tried to create two separate point cuts and then join them on advice calls but even that didnt work as I think I do not know the right format of the void method point cut declaration.

I had the following:

@Pointcut("execution(void * *(..))")
    public void voidMethodPointcut() {}

But this throws malformed pointcut expression Exception.

I am new to Spring and would really appreciate your help on this.

For methods annotated by @Service your pointcut expression should look like this:

execution(@your.package.name.Service void *.*(..))

And for all methods of classes annotated by @Service - like this:

execution(void (@your.package.name.Service *).*(..))

Its not the methods that are annotated. Its the classes. – Nick Div Aug 15 '16 at 20:58
I gave you both, because it wasn't clear from your description. So, you can use second expression – Eugene Kuleshov Aug 15 '16 at 22:13
Aah my bad. Thanks, let me try this out. – Nick Div Aug 16 '16 at 00:08
I think this variant is a little more expressive and readable: `execution(void * *(..)) && @target(@your.package.name.Service)` – kriegaex Aug 20 '16 at 09:54
How does this reference @Service? This references classes named "Service" no? These examples aren't working for me. – gene b. Nov 21 '18 at 14:42
@krigaex your version gives me the error "The entity name must immediately follow the '&' in the entity reference." (it doesn't like the `&& @target ...`) – gene b. Nov 21 '18 at 14:46
