I have CDI interceptor class annotated with javax.interceptor.InterceptorBinding @LogBinding, defined as follows:
@InterceptorBinding
@Retention(RUNTIME)
@Target({METHOD, TYPE})
public @interface LogBinding {}
Then I use annotation on EJB bean:
@Alternative
@Stateless
@LogBinding
public class FooService {
@Asynchronous
public fooMethod() {
}
}
I invoke fooMethod from another bean. The problem is that interceptor isn't called. Everything works when I change @LogBinding annotation to @Interceptors({LogInterceptor.class}) on the FooService. I don't know if it may have impact but FooService is market as @Alternative, because it's injected in other places as EJB bean, below is the producer field:
@Default
@Produces
@EJB
private FooService fooService;
@Interceptor
@LogBinding
@Priority(Interceptor.Priority.APPLICATION)
public class LogInterceptor {
@AroundInvoke
public Object invoke(final InvocationContext invocationContext) throws Exception {
System.out.println("it works");
}
}
Why it doesn't work?
You also have to annotate your interceptor class with that binding in order for it to know which class to use as the interceptor
@LogBinding
@Interceptor
public class LogInterceptor {...}
