cdi

问题 I'm trying to implement some sort of auditing in a Java EE JPA application on GlassFish 3. I have added a @EntityListeners annotation on my @MappedSuperclass entity, the listener has the @PrePersist and @PreUpdate annotation on its methods which are invoked happily at runtime. In these methods, I'm trying to use ( @Inject ) a @Named , @Stateful , @SessionScoped bean ( UserSession ) in order to get current user's id. The listener class has no annotations at all. The problem is that I can't get

问题 LoggerProducer.java is a class used to produce Loggers to be injected in CDI beans with: @Inject Logger LOG; Full code: import javax.ejb.Singleton; /** * @author rveldpau */ @Singleton public class LoggerProducer { private Map<String, Logger> loggers = new HashMap<>(); @Produces public Logger getProducer(InjectionPoint ip) { String key = getKeyFromIp(ip); if (!loggers.containsKey(key)) { loggers.put(key, Logger.getLogger(key)); } return loggers.get(key); } private String getKeyFromIp

问题 I try to use Jersey 2.1 and CDI in my Java EE 7 project which is deployed on Glassfish 4.0. Jersey modules depend on Guava libraries. But using Guava libraries (14.0.1) with CDI results the following exception being thrown. CDI deployment failure:WELD-001408 Unsatisfied dependencies for type [Set<Service>] with qualifiers [@Default] at injection point [[BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] @Inject com.google.common.util.concurrent.ServiceManager(Set<Service>)]

问题 Coming from a Guice background, I know that it is possible to seed an object value from a scope using. scope.seed(Key.get(SomeObject.class), someObject); I suppose one could do this by registering a Bean that gets a value from an AbstractBoundContext , but examples just seeding one value from a Custom Scope seem hard to find. How do I create a custom scope that seeds a value that can be injected elsewhere? Edit: I am currently using the following workaround, that can be injected in an

问题 I really need your help. I'm working on this problem for weeks or months now. I apologize for the long post, but I want to explain the problem and my settings as precisely as possible. My JAVA EE 6 web application mainly contains 3 Servlets: a javax.faces.webapp.FacesServlet , a StreamingServlet extending javax.servlet.http.HttpServlet and a ClientServlet extending org.eclipse.jetty.websocket.WebSocketServlet . I want to use CDI with these Servlets but it only works for the FacesServlet, to

问题 I'm using Omnifaces 1.8.1 and Whenever I deploy my application to Glassfish I get the following warning which causes some delay in the deploy process. Warning: WELD-001519 An InjectionTarget implementation is created for an abstract class org.omnifaces.eventlistener.DefaultHttpSessionListener. It will not be possible to produce instances of this type! Warning: WELD-001519 An InjectionTarget implementation is created for an abstract class org.omnifaces.eventlistener

问题 I am programming in a Java SE environment using WELD-SE for dependency injection. Therefore dependencies of a class look something like this: public class ProductionCodeClass { @Inject private DependencyClass dependency; } When writing a unit test for this class I am creating a mock for DependencyClass and as I don't want to start a complete CDI environment for every test I run, I "inject" the mock manually: import static TestSupport.setField; import static org.mockito.Mockito.*; public class

问题 I am wondering how can I use the Instance in JUnit4 with Spring @Inject Instance<IMyInterface> interfaces; If I use @Inject List<IMyInterface> interfaces; It works in Spring but not with CDI. Also, we can use Provider with both CDI and Spring but it's not Iterable. 回答1: The @Inject annotation comes from JSR-330-Dependency Injection for Java. Spring knows this annotation and briefly said, Spring treats it as an alternative to @Autowired . That's it. However, the Instance is part of JSR 299 -

问题 I'm using JSF 2.0, CDI 1.0 within WebSphere App Server v8.0.0.5. I have a bizarre situation... Upon successful login, a CDI session-scoped bean is created, and the user is redirected to a welcome page. The session-scoped bean is injected into a request-scoped bean referened on the welcome page. The problem is that the session-scoped bean ONLY retains its field values upon first successful login per browser. I've tried the same user using Chrome, Firefox, and even IE. If I log out or restart
