org.jboss.seam.intercept.Interceptor limits the number of Interceptors

[larshuber]

Hi

Currently this is not working.

@Interceptors({FirstInterceptor.class, SecondInterceptor.class})

The Interceptor implementation of 2.1 nightly build restricts the @Interceptors annotation to exactly 1 interceptor. The following code shows the cause.

   public Interceptor(Class[] classes, Annotation annotation, Component component) 
   {
      if (classes.length!=1)
      {
         //TODO: remove this silly restriction!
         throw new IllegalArgumentException("Must be exactly one interceptor when used as a meta-annotation");
      }
      userInterceptorClass = classes[0];

Will this restriction be removed or what would be an appropriate workaround?

thanks
Lars

Lars, since this issue is quite old, did u apply a patch or implement some kind of workaround for it?

I don't know if it's a workaround or actually standard use. I created for each Interceptor it's own annotation. These annotations you can put on your classes instead of @Interceptors(...) directly.

@Target({ ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Interceptors(ServiceExceptionInterceptor.class)
public @interface ServiceException {
}

@Target({ ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Inherited
@Interceptors(ServiceSecurityInterceptor.class)
public @interface ServiceSecurity {
}

@ServiceSecurity
@ServiceException
public class BaseService implements Serializable {
}
