I have created a CDI (WELD) interceptor that works and intercept what it is supposed to intercept.
@MyInterceptorBinding
@Interceptor
@Dependent
public class MyInterceptor implements Serializable {
private int myIntegerField;
@AroundInvoke
public Object interceptMethod(InvocationContext ctx) throws Exception {
// Do some operations and side effects on myIntegerField;
try {
Object result = ctx.proceed();
return result;
} catch (Exception e) {
throw e;
}
}
public List<Class<?>> getMyIntegerField() {
return myIntegerField;
}
}
Where MyInterceptorBinding is an interceptor binding:
@Inherited
@InterceptorBinding
@Target({TYPE, METHOD, PARAMETER, FIELD})
@Retention(RetentionPolicy.RUNTIME)
public @interface MyInterceptorBinding {}
I would like to inject my interceptor into a bean class like this:
@ApplicationScoped
public class MyBean implements Serializable {
@Inject
private MyInterceptor interceptor;
public void aMethod(){
int var = interceptor.getMyIntegerField();
// use var in some way...
}
}
but this injection brings to an error:
Unsatisfied dependencies for type MyInterceptor with qualifiers @Default
at injection point [BackedAnnotatedField] @Inject private trials.MyBean.interceptor
How can i overcome this issue? Is a problem related to the fact that is an interceptor? Should i use the CDI portable extension facility? And, if so, how?
