类型QueueSession的CDI-不满意的依赖关系

Question

我正在尝试编写注释来注入JMS资源。这里是我的代码

public class JMSResourceProducer { 

    private static final String WL_INIT_CONN_FACTORY ="weblogic.jndi.WLInitialContextFactory"; 
    private String WL_SERVER_URL = "URL"; 
    private String QF ="QFNAME"; 
    private String QQ ="QNAME"; 

    public InitialContext createInitialContext() throws NamingException { 
     Hashtable properties = new Hashtable(); 
     properties.put(Context.INITIAL_CONTEXT_FACTORY, WL_INIT_CONN_FACTORY); 
     properties.put(Context.PROVIDER_URL, WL_SERVER_URL); 
     return new InitialContext(properties); 
    } 

    @Produces @Image2000 
    public QueueSession createQueueSession() throws NamingException, JMSException { 
     InitialContext initialContext = createInitialContext(); 
     QueueConnectionFactory queueConnectionFactory = (QueueConnectionFactory) initialContext.lookup(QF); 
     QueueConnection queueConnection = queueConnectionFactory.createQueueConnection(); 
     return queueConnection.createQueueSession(true, 0); 
    } 

    @Produces @Image2000 
    public Queue createQueue () throws NamingException { 
     InitialContext initialContext = createInitialContext(); 
     Queue queue = (Queue)initialContext.lookup(QQ); 
     return queue; 
    } 
} 

这是我如何使用它在我的课

@Inject @Image2000 
    private QueueSession queueSession; 

    @Inject @Image2000 
    private Queue jmsQueue; 

我的注释

@Qualifier 
@Target({TYPE, METHOD, PARAMETER, FIELD}) 
@Retention(RetentionPolicy.RUNTIME) 
public @interface Image2000 { 
} 

但我得到下面的错误我Wildfly启动时..

Caused by: org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied dependencies for type QueueSession with qualifiers @Image2000 

注射时点[UnbackedAnnotatedField] @Inject @ Image2000 .queueSession

任何线索什么是我的生产者类错？

根据bean.xml中定义的发现模式，您可能需要使用定义注释的Bean（Dependent，ApplicationScoped或其他更适合的）来注释JMSResourceProducer。
