[weld-issues] [JBoss JIRA] Commented: (WELD-356) @PersistenceContext not injected in target bean when bean is intercepted

[Koichi Kobayashi (JIRA)]

    [ https://jira.jboss.org/jira/browse/WELD-356?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12506733#action_12506733 ] 

Koichi Kobayashi commented on WELD-356:
---------------------------------------

FieldInjectionPoint class has two inject() methods.

inject(Object declaringInstance, BeanManagerImpl manager, CreationalContext<?> creationalContext) injects to @Inject.
inject(Object declaringInstance, Object value) injects to @Resource, @PersistenceContext, etc.

WELD-225 (probably r:4370) fixes only first one.
so, @Resource does not yet work with proxy.
My patch fixes second one in the same way as first one.

> Say you have this bean :
> @MyInterceptorBinding
> public class MyServiceBean implements MyService {
> 	@PersistenceContext
>         protected EntityManager entityManager;
> 	
> 	@Inject @Any
> 	private Event<MyEvent> myEvent;
>     
>         public Object persist(Object obj) {
> 		entityManager.persist(obj);
> 		
> 		myEvent.fire(new MyEvent());
> 		
>                 return obj;
>      }
> }
> Where @MyInterceptorBinding is a simple interceptor binding with a trivial interceptor implementation :
> @MyInterceptorBinding @Interceptor
> public class MyInterceptor {
> 	@AroundInvoke
> 	public Object doInvoke(InvocationContext context) {
> 		Object result = null;
> 		
>     	try {
>     		return context.proceed();
>     	}
>     	catch (Exception e) {
>                 throw new RuntimeException("error", e);
> 	}
> }
> The MyEvent field of the bean is correctly injected, but the entityManager is null. 
> Note that if injecting @PersistenceContext EntityManager entityManager in the interceptor works fine.
> When the bean is not intercepted, its entityManager field is correctly injected.
