Question

我正在尝试编写注释来注入JMS资源。这是我的代码

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;
    }
}

这就是我在课堂上使用它的方式

@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 {
}

但是当我的Wildfly开始时我的误差低于......

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

注入点[UnbackedAnnotatedField] @Inject @ Image2000 .queueSession

我的制片人课有什么问题吗？

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