Re: [aspectj-users] Exception cache with aspectj

[Andy Clement <andrew.clement@xxxxxxxxx>]

Yes, if the exception is re-thrown you will see it with something like execution() and after throwing advice. If the exception is handled internally in the method you could use the handler() joinpoint to see it:

catch (Exception e) {

  log.error("Exception occurred");

}

before(Exception ex): handler(Exception) && args(ex) {

 // do something with the exception

}

The advice will run at the start of the catch block.

Thanks Andy for clarification.

My confusion is on how to handle the cache exception such as follows.

If the cache block throws exception i can use a handler on get the exception.
cache(Exception e){
throw e;
}

Where as if the developer just did like below, handler cannot caught it. How to proceed in this case.
cache(Exception e){
log.error("Exception occured");
}

Thanks,
Krishna

There is no joinpoint for array access so you cannot catch the exception unfortunately.

Some form of support could be added to AspectJ, but is not currently on the radar.

cheers,

Hi ,
Can anybody faced a similar situation like this.

How to specify a pointcut and advice for caching this type of exception.

                try{
                        int array[]={10,20,30};
                        System.out.println("The value of array is" +array[5]);
                   }
                catch(ArrayIndexOutOfBoundsException aiob){
                         aiob.printStackTrace();
                }

Thanks,
Krishna
