Throwing exception in @Before, catching in @AfterThrowing

[sbertl000]

Hi,

i created a @Before Advice that throws an exception and tried to catch it in another @AfterThrowing, but it does not work.

if the exception is not thrown in the advice, but directly in the method, it works.

if it is thrown in the advice, the @AfterThrowing is not executed.

Why does it behave like that?

Thanks!

The ordering of the advice... I suspect the afterthrowing is applied AFTER the Before and thus it never sees the exception, change the order.

hmm, that does not change anything.
The point is, that if the Before Advice does not throw an exception, the After Advices are executed at the right time.

Because it is applied after the before advice... So when you are in your method the advice is applied.

advice1 -> advice2 -> method

Advice 1 is your before
Advice 2 is your after throwing

So if you before is throwing an exception that is not going to be seen by the after throwing advice.

I changed it

AfterThrowing Advice has Order: Ordered.HIGHEST_PRECEDENCE + 4
BeforeAdvice has Order: Ordered.HIGHEST_PRECEDENCE + 5

So the AfterThrowing should be executed first. But it does not work...

thx

Post your code and configuration...

Also Ordered.HIGHEST_PRECEDENCE is actually Integer.MAX_VALUE so adding something makes it run out of the integer range! Which actually leads to your Before advice being executed before the after advice!

Before: -2147483644
