Is it possible to return value from Spring AspectJ?

Question

I'm returning value from my controller. Let it be ResponseEntity<String> type.

Controller returns:

new ResponseEntity<String>("{\"msg\":\"success\"}",HttpStatus.OK);

Following value goes to my spring aspect. I am receiving this object in following code:

@AfterReturning(pointcut = "somePointcut()",returning = "retVal") public ResponseEntity<String> adviceTest3(Object retVal) { //here i have access to controller's object return new ResponseEntity<String>("{\"msg\":\"changed value within aspect\"}",HttpStatus.OK); }

I'm aware that there is @AfterReturning. Is it any way manipulate data and achieve that?

With @AfterReturning, no. Quote from the documentation

An after returning advice has access to the return value (which it cannot modify), invoked method, methods arguments and target.

You could use @Around instead.
