cdi

问题 I have a CDI bean where I'm using @ConversationScoped. When I try to do an @Inject for the Conversation object, I get a NPE. @ConversationScoped @Named("customerbean") public class CustomerBean implements Serializable { @Inject private Conversation conversation; private static final EntityManagerFactory emf = Persistence.createEntityManagerFactory("ba"); private EntityManager em; private Customer customer; boolean disabled; public CustomerBean() { beginConversation(); customer = new Customer(

问题 Problem Using CDI I want to produce @ApplicationScoped beans. Additionally I want to provide a configuration annotation to the injection points, e.g.: @Target({ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER}) @Retention(RetentionPolicy.RUNTIME) public @interface Configuration { String value(); } I do not want to write a separate producer for each different possibility of value . Approach The usual way would be to make a producer and handle the injection point annotations:

问题 I am using JUnit and embedded glassfish to test some code using CDI. This seems fairly straightforward but I must be missing something. I've created a simple project which demonstrates the problem. https://github.com/dantwinkler/container-test-embedded-glassfish This is the stack trace if no parameters are set. If the domain.xml is specified in the embedded container properties the tests still fail but because it says the test can not be found. The next step is to try to get things working

问题 I want to inject the current user using @Inject @Current User across all layers (i.e. web layer, EJB layer). In order to do this, I have the following CDI Producer method: @Named @SessionScoped public class UserController { @Resource SessionContext sessionContext; @EJB UserDao userDao; @Produces @Current public User getCurrentUser() { String username = sessionContext.getCallerPrincipal().getName(); User user = userDao.findByUsername(username); } } @Qualifier @Target({TYPE, METHOD, PARAMETER,

问题 I have a @SessionScoped @Named bean with a @Producer method for a user object: @Named @SessionScoped public class UserBean implements Serializable { //... @Named @Produces @LoggedIn @SessionScoped public MyUser getCurrentUser() {return user;} } This works fine in my setup (JBoss-7.1.1-Final) and it's no problem to access the user fields from JSF pages with #{currentUser.name} . The qualifier is org.jboss.seam.security.annotations.LoggedIn . Now I want to @Inject this user in a field in

问题 I've just switched to Weld to make use of CDI JSF 2 Beans + conversation scope. Here's my maven dependency : <dependency> <groupId>org.jboss.weld.servlet</groupId> <artifactId>weld-servlet</artifactId> <version>1.0.1-Final</version> <type>jar</type> <scope>compile</scope> </dependency> Here's the entry in my web.xml : <listener> <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class> </listener> One thing i noticed immediately is i just need to reload my tomcat 7 for like

问题 I have an Enterprise Application Archive ( EAR ) containing multiple backend modules ( EJB ) as well as some web modules ( WAR ). The Event gets fired inside one of the backend modules: @Inject private Event<MyEvent> myEvent; ... public void fireEvent() { myEvent.fire(new MyEvent()); } ... It can be observed in any of the other backend modules with code like this: public void listener(@Observes MyEvent myEvent) { .. } But I can't retrieve the event inside the WARs. Is this because of
