问题描述
我试图手动定义JMSMessageID(message.setJMSMessageID(uniqueid)) ,但服务器忽略此修改,并传递内置生成的JMSMessageID的消息。
根据规范,我没有找到关于如何重复数据消除消息的引用。 p>
在HornetQ中,为了处理这个问题,我们需要在邮件定义上声明HQ特定的属性org.hornetq.core.message.impl.HDR_DUPLICATE_DETECTION_ID。
ie:
消息jmsMessage = session.createMessage();
String myUniqueID =这是我唯一的id; //可以使用UUID这个
message.setStringProperty(HDR_DUPLICATE_DETECTION_ID.toString(),myUniqueID);
有人知道ActiveMQ是否有类似的解决方案?
您应该看看Apache Camel,它提供了一个能够与任何JMS提供程序配合使用的Idempotent消费者组件,请参阅:
使用结合ActiveMQ组件使得使用JMS非常简单,请参阅:
There's a way to suppress duplicated messages on a queue defined on ActiveMQ server?
I tried to define manually JMSMessageID, (message.setJMSMessageID("uniqueid")), but server ignores this modification and deliver a message with built-in generated JMSMessageID.
By specification, I didn't found a reference about how to deduplicate messages.
In HornetQ, to deal with this problem, we need to declare the HQ specific property org.hornetq.core.message.impl.HDR_DUPLICATE_DETECTION_ID on message definition.
i.e.:
Message jmsMessage = session.createMessage();
String myUniqueID = "This is my unique id"; // Could use a UUID for this
message.setStringProperty(HDR_DUPLICATE_DETECTION_ID.toString(), myUniqueID);
Somebody knows if there's a similar solution for ActiveMQ?
You should look at Apache Camel, it provides an Idempotent consumer component that would work with any JMS provider, see: http://camel.apache.org/idempotent-consumer.html
Using that in combination with the ActiveMQ component makes using JMS quite simple, see:http://camel.apache.org/activemq.html
