Question

I’m using Java EE 6 & Jboss AS7.1 and try to use interceptor binding (Example from jboss site).

I have an InterceptorBinding annotation:

@InterceptorBinding
@Target({ ElementType.METHOD, ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
public @interface GeoRestrictedEquipment {
}

The interceptor:

@GeoRestrictedEquipment
@Interceptor
public class GeoRestrictedEquipmentInterceptor {

    @EJB EquipmentDao equipmenttDao;    
    @EJB SecurityService securityService;    

    @AroundInvoke
    public Object checker(InvocationContext ctx) throws Exception {
        Integer id = (Integer) ctx.getParameters()[0];
        Equipment equipment = equipmenttDao.findById(id);
        GeoChecker.check(equipment.getSite(), securityService.getUser());

        return ctx.proceed();
    }
}

And a bean:

@Stateless
@LocalBean
@SecurityDomain(Realm.NAME)
@RolesAllowed({ Roles.REGISTERED })
public class PumpService implements PumpServiceLocal {

    @Override
    @GeoRestrictedEquipment
    public PumpInfos getPumpInfos(Integer pumpId) {
        /* ... */
    }
}

But the interceptor is not called… What do I miss from the example ?

The interceptor is called when I write this:

@Override
@Interceptors({GeoRestrictedEquipmentInterceptor.class})
public PumpInfos getPumpInfos(Integer pumpId) {
    /* ... */
}

Thanks for your help.

Answer 1

Did you enable your interceptor as described in the referenced example?

By default, a bean archive has no enabled interceptors bound via
interceptor bindings. An interceptor must be explicitly enabled by
listing its class under the element of the beans.xml
file of the bean archive.
