Question

仅在其中一个订阅消息侦听器中多次获取相同的消息。我正在使用weblogic服务器并使用Ejb。我正在使用持久订阅。我已经尝试过SHARED和CLONED两个但是分开但问题仍然相同

    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = ""),
    @ActivationConfigProperty(propertyName = "sharedSubscription", propertyValue = "TRUE")
   })

克隆

    @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
    @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
    @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = ""),
    @ActivationConfigProperty(propertyName = "cloneSupport", propertyValue = "ENABLED"),

所以我正在使用实现消息监听器的Abstarct类

    public void onMessage(Message message) {
    LOGGER.info("Receive Host message: {}", message);

我解析消息然后用一些不同的方法我发送

protected void createAndSendAckMessage(String msgToSend, Message request) throws JMSException {
    Connection connection = null;
    Session session = null;
    MessageProducer producer = null;

    try {
        connection = getConnectionFactory().createConnection();
        session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

在订阅者我扩展该抽象类并定义所有@ActivationConfigProperty

的不同MDB中

我正在创建一个.binding文件来指定端口，主机，qmanager和主题信息

通过Subscription IBM MQ
