CDI Interceptor doesn't get executed

[si.ret]

Hi together,

currently I'd like to test an interceptor which logs occuring exceptions via Arquillian. I've created an interceptor, an InterceptorBinding annotation and annotated my class under test accordingly. But when I'm executing the test the interceptor won't be called. Does Arquillian support CDI interceptors?

My interceptor:

@Exceptional
@Interceptor
public class ExceptionInterceptor {
    @AroundInvoke
    public Object handleException(InvocationContext ctx) throws Exception {
        try {
            Object o = ctx.proceed();
            System.out.println("No exception!!");
            return o;
        } catch (Exception e) {
            System.out.println("Exception!!");
            return null;
        }
    }
}

My interceptor binding annotation:

@InterceptorBinding
@Target({METHOD, TYPE})
@Retention(RUNTIME)
public @interface Exceptional {}

My beans-test.xml

<beans xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="
      http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/beans_1_0.xsd">
    <interceptors>
        <class>com.xxx.gssn.audit.core.exception.ExceptionInterceptor</class>
    </interceptors>
</beans>

My test class:

@RunWith(Arquillian.class)
public class ExceptionHandlingTest {

    @Deployment
    public static Archive<?> deploy() {
        return ShrinkWrap
            .create(JavaArchive.class)
            .addClasses(ExceptionBean.class, Exceptional.class, ExceptionInterceptor.class)
            .addAsManifestResource("META-INF/beans-test.xml", "beans.xml");
    }

    @Inject
    private ExceptionBean bean;

    @Test
    public void testInterceptor() {
        String hello = bean.sayHello();
        assertThat("Hi!", is(hello));
    }
}

Thanks in advance for any comment...

Hi Simon!

I have the same problem with my tests.

I have checked the contect of the data directory of my JBoss AS. I have unpacked the content. The structure looks like:

content

  WEB-INF

    bean.xml (empty)

    lib

      test.jar

        com

        META-INF

          bean.xml (my file with interceptors)

        org

That means, Arquillian adds two bean.xml to the deployment. Perhaps this is a problem.

I had the same problem you described.  This article help me resolve my issue:

The placement of the beans.xml and test class matters. If the test class is in a BDA (like WEB-INF/classes) that has an empty beans.xml file, then interceptors are disabled for that BDA (the default behavior). Therefore, you'd want to have finer control over the ShrinkWrap deployment to enable interceptors for all CDI beans whose method invocations are to be intercepted. The best way to handle this for micro-deployments, is to create a WebArchive and add all your classes to WEB-INF/classes. You'd then need to add the interceptor to the beandescriptor placed in WEB-INF/beans.xml.

Additionally, I found it important to apply the @NonBinding annotation to certain attributes of the @InterceptorBinding annotated type. This is of course not applicable if your interceptor binding annotation does not have any attributes.

Had the same issue. Found that injecting real cdi bean works with interceptors, but when injected through interface it fails.
