Hi Marcel,
here are some examples:
1. Looking for special annotations on service methods
@Authorize
public void executeSomethingOnlyAllowedIfUserIsAuthorized() {
...
}
All method that is annotated with @Authorize will be handled with a `before`
aspect which is checking some credentials.
2. Default Logging for thrown Exceptions, Bundle start/stop, etc.
Is it clear what I want to do?
I'm currently looking how the weaving hooks are working. But if I register an
`WeavingHook` impl and start it with some of my bundles, nothing happens. So
the weave method will not be called :( Do not know what I'm doing wrong.
WeavingHookImpl Code:
public class WeavingHookImpl implements WeavingHook {
@Override
public void weave(WovenClass arg0) {
System.out.println("load class " + arg0.getClassName());
}
}
Activator Code:
public class Activator implements BundleActivator {
@Override
public void start(BundleContext arg0) throws Exception {
System.out.println("start weaving bundle");
arg0.registerService(WeavingHook.class, new WeavingHookImpl(),
null);
}
@Override
public void stop(BundleContext arg0) throws Exception {
// TODO Auto-generated method stub
}
}
Greetings.
Christian
