Hello,
there has been long discussions on checked vs. unchecked exceptions.
I don't want to start this discussion again.
I know, the opposite behaviour can be achieved by "declare soft ..."
In my case i have to convert any exception to a layer-specific checked
exception.
This behaviour shall be controllable (on/off) with the presence of a
method-annotation.
Here an example:
@DSExceptionTranslator
private void anyMethod() throws DSException {
throw new PersistException();
}
Obvious the above code will normally generate an unhandled-exception-error.
I expected the following advice to solve that.
after() throwing (Exception ex) throws DSException : mypointcut() {
throw new DSException(ex);
}
But the unhandled-exception-error did not disappear!
So i added a "declare soft":
declare soft : Exception : mypointcut();
The unhandled-exception-error disappears, but this did not solve my problem
because the generated code looks like this:
try {
try {
throw new PersistException();
} catch(Exception exception) {
ThrowDSExceptionAspect.aspectOf().ajc$afterThrowing$com_gid_bip_dataservice_aj_ThrowDSExceptionAspect$1$e66f2abe(exception);
throw exception;
}
} catch(Exception exception1) {
if(exception1 instanceof RuntimeException)
throw exception1;
else
throw new SoftException(exception1);
}
As we can see, my new DSException is softened too and is thrown as a
SoftException.
It seems that the code for "declare soft" will always be weaved as last
step.
I tried "declare precedence" to control the weaving-process, but nothing
changes!
==== Is there any other way to avoid the unhandled-exception-error? ====
I found similar Questions in several lists, but the solutions all did not
work with the current release of AspectJ 1.6.12.M1 (ajdt 2.1.3).
Thank you in advance
