红帽全球峰会20.7.3. 为 Java Messaging Service (JMS) 客户配置服务器
属性
第二个途径是设置 HornetQConnectonFactory 上的
除了上面两个途径以外，另外一个方法是通过连接工厂设置专有的消息组 ID。这将依次将通过这个连接工厂发送的所有消息的属性
JMSXGroupID 用于为 JMS 客户识别消息组。如果您想发送包含不同消息的消息组到某个消费者，您可以对不同的消息设置相同的 JMSXGroupID：
Message message = ...
message.setStringProperty("JMSXGroupID", "Group-0");
producer.send(message);
message = ...
message.setStringProperty("JMSXGroupID", "Group-0");
producer.send(message);
autogroup 属性为 "true"。HornetQConnectionFactory 将选取一个随机的唯一消息组 ID。您可以这样在服务器配置文件（standalone.xml 和 domain.xml）里设置 autogroup 属性：
<connection-factory name="ConnectionFactory">
<connectors>
<connector-ref connector-name="netty-connector"/>
</connectors>
<entries>
<entry name="ConnectionFactory"/>
</entries>
<autogroup>true</autogroup>
</connection-factory>
JMSXGroupID 设置为指定的值。要在连接工厂上设置专有的消息组 ID，请编辑服务器配置文件（standalone.xml 和 domain.xml）里的 group-id 属性：
<connection-factory name="ConnectionFactory">
<connectors>
<connector-ref connector-name="netty-connector"/>
</connectors>
<entries>
<entry name="ConnectionFactory"/>
</entries>
<group-id>Group-0</group-id>
</connection-factory>
