如何在 weblogic 10.3 服务器上延迟 JMS 消息

Question

I want to delay message delivery by certain time which will be different for each message.

I referred weblogic 10.3 WLMessage documentation which recommends using javax.jms.Message.getIntProperty("JMS_BEA_DeliveryTime") .

However I'm unable to figure out how do I set JMS_BEA_DeliveryTime as INTEGER . I was expecting it to be long .

I'm unable to find out any documentation about this attribute JMS_BEA_DeliveryTime to undesratand how to set and use it. Can anybody give example about how to set the desired delivery time or link to documenation of use of this attribute.

My code looks like typical use of Spring JMS template:

 jmsTemplate.send(destination, new MessageCreator() {
                public Message createMessage(Session session) throws JMSException {
                  TextMessage message = session.createTextMessage(textMessage);
                  return message;
                }
            });

I was wondering if it is possible to set header for delivery time before returning message.

Answer 1

很好的文章，其中包含为不同的 JMS 提供程序延迟交付的示例，包括 WL。

Answer 2

Well there is this page which states

JMS Delivery Time: The earliest absolute time at which 
                   a message can be delivered to a consumer.

It should be trivial to set with Message.setIntProperty(...) , there is not much mention as to what the time actually constitutes though, although I did find this article which suggests milliseconds from now.

Hope that helps.
