问题描述

有没有办法抑制 ActiveMQ 服务器上定义的队列上的重复消息?

Is there a way to suppress duplicated messages on a queue defined on ActiveMQ server?

我尝试手动定义 JMSMessageID，(message.setJMSMessageID("uniqueid"))，但服务器忽略了这个修改并使用内置生成的 JMSMessageID 传递消息.

I tried to define manually JMSMessageID, (message.setJMSMessageID("uniqueid")), but server ignores this modification and deliver a message with built-in generated JMSMessageID.

按照规范，我没有找到有关如何删除重复消息的参考.

By specification, I didn't found a reference about how to deduplicate messages.

在 HornetQ 中，为了处理这个问题，我们需要在消息定义中声明 HQ 特定的属性 org.hornetq.core.message.impl.HDR_DUPLICATE_DETECTION_ID.

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.

即:

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);

有人知道 ActiveMQ 是否有类似的解决方案?

Somebody knows if there's a similar solution for ActiveMQ?

推荐答案

你应该看看 Apache Camel，它提供了一个可以与任何 JMS 提供者一起工作的幂等消费者组件，请参阅:http://camel.apache.org/idempotent-consumer.html

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

将它与 ActiveMQ 组件结合使用使得 JMS 的使用变得非常简单，请参阅:http://camel.apache.org/activemq.html

Using that in combination with the ActiveMQ component makes using JMS quite simple, see: http://camel.apache.org/activemq.html
