[aspectj-users] Problem with @Aspect using generics
|
Hello,
I have following problem with following Aspect:
@Aspect
public class CounterAspect extends AbstractMoskitoAspect {
@Around(value = "execution(* *(..)) && (@annotation(method))")
public Object countMethod(ProceedingJoinPoint pjp, Count method) throws Throwable {
return count(pjp, method.producerId(), method.subsystem(), method.category());
}
@Around(value = "execution(* *(..)) && (@annotation(method))")
public Object countByParameter(ProceedingJoinPoint pjp, CountByParameter method) throws Throwable {
return countByParameter(pjp, method.producerId(), method.subsystem(), method.category());
}
@Around(value = "execution(* *.*(..)) && (@within(clazz))")
public Object countClass(ProceedingJoinPoint pjp, Count clazz) throws Throwable {
return count(pjp, clazz.producerId(), clazz.subsystem(), clazz.category());
}
private Object countByParameter(ProceedingJoinPoint pjp, String aProducerId, String aSubsystem, String aCategory) throws Throwable {
....
It works. However, since I have two similar aspects that differ only in using some internal classes, I made my super class using generics:
public class AbstractMoskitoAspect<S extends IStats> {
@Aspect
public class CounterAspect extends AbstractMoskitoAspect<CounterStats> {
this breaks the build instantly with the very unhelpful error message:
[ERROR] Failed to execute goal org.codehaus.mojo:aspectj-maven-plugin:1.4:compile (default) on project moskito-aop: Compiler errors:
[ERROR] error at @Around(value = "execution(* *(..)) && (@annotation(method))")

what am i doing wrong here?
aspectj 1.6.11, mvn 3, mvn aspectj plugin 1.4
how to reproduce:
edit net.anotheria.moskito.aop.aspect.CounterAspect, change
public class CounterAspect extends AbstractMoskitoAspect {
to
public class CounterAspect extends AbstractMoskitoAspect<CounterStats> {
run mvn clean install
thanks for your time
Leon
