I'm trying to implement a tracing aspect using the pertypewithin instantiation model. In this way, I'll be able to use one logger per class per type.
From some examples arround the we I can find this code to init the logger:
public abstract aspect TraceAspect pertypewithin(com.something.*) {
abstract pointcut traced();
after() : staticinitialization(*) {
logger = Logger.getLogger(getWithinTypeName());
}
before() : traced() {
logger.log(...);
}
//....
}
unfortunately, I'm not able to fully translate thi开发者_Go百科s to the @AspectJ syntax (it's a project requirement outside my control), especially the part in with I need to setup the logger, executing that code only once.
Is this possible?
Thanks,
@Aspect("pertypewithin(com.something.*))")
public abstract class TraceAspect {
Logger logger;
@Pointcut
public abstract void traced();
@Pointcut("staticinitialization(*)")
public void staticInit() {
}
@After(value = "staticInit()")
public void initLogger(JoinPoint.StaticPart jps) {
logger = Logger.getLogger(jps.getSignature().getDeclaringTypeName());
}
@Before(value = "traced()")
public void traceThatOne(JoinPoint.StaticPart jps) {
logger.log(jps.getSignature().getName());
}
}
