如何通过 spring 集成将消息传递给生产者(定义为将消息发送到 activemq 的方法(。 实际要求是，我需要将数据插入数据库并将该数据移动到 activemq 中的队列中，这两个操作需要并行进行。我该怎么做。
<jms:message-driven-channel-adapter id="helloWorldJMSAdapater" destination="helloWorldJMSQueue" connection-factory="jmsConnectionFactory"

使用<publish-subscribe-channel/>并将两个端点都订阅到它。默认情况下，它们将串行执行，或者如果您向通道添加task-executor，则并行执行。
