ApacheActiveMQ 5.3-如何配置队列以拒绝重复消息?

(我已经在谷歌上搜索了几个小时了…)

编辑:

ActiveMQSession实现有以下几行:

        // transform to our own message format here
            ActiveMQMessage msg = ActiveMQMessageTransformation.transformMessage(message, connection);

        // Set the message id.
        if (msg == message) {
            msg.setMessageId(new MessageId(producer.getProducerInfo().getProducerId(), sequenceNumber));
        } else {
            msg.setMessageId(new MessageId(producer.getProducerInfo().getProducerId(), sequenceNumber));
            message.setJMSMessageID(msg.getMessageId().toString());
        }

有什么想法,除了修改他们的代码?
