[aspectj-users] instrumenting JAXB-generated classes

["Alec Lebedev" <alec.lebedev@xxxxxxxxxxxx>]

Hi,

 

I am using JAXB to generate Java classes based on the given XML schema. I then try to weave aspects in the generated classes, but I can’t seem to capture when fields of JAXB-generated classes get set at runtime.

 

Below are the two advices which I am trying to weave in the TXmlEntity JAXB-generated class. Note that the first advice fires up just fine and prints out correct XmlIds. However, the second aspect never gets fired. I don’t understand how xmlId field in TXmlEntity class gets set if the second (setter) advice never fires up and the first (getter) one prints out correct xmlId values?

 

after (TXmlEntity var) : get (* TXmlEntity.*) && this(var) && !cflowbelow(adviceexecution())

{

            logger.error("Reading: " + var.getXmlId());

}

 

after (TXmlEntity var) : set (* TXmlEntity.*) && this(var) && !cflowbelow(adviceexecution())

{

            logger.error("Setting: " + var.getXmlId());

}

 

TXmlEntity is just a POJO class shown below.
