Spring Integration向JMS Topic发送首条消息耗时过长问题排查

我使用Spring Integration向Red Hat AMQ 7.8.2的JMS Topic生产消息时发现：应用启动或重启后，发送首条消息耗时3-4秒，但后续消息仅需40-50毫秒即可完成。推测该耗时差异源于连接工厂创建及与Broker建立连接的过程。

相关配置代码 #

<si-jms:outbound-channel-adapter id="communication"
   connection-factory="connectionFactoryCached"
   channel="communicationChannel"
   destination-name="${communications.topic}"
   pub-sub-domain="true" />

<bean id="connectionFactory"
   class="javax.jms.ConnectionFactory"
   factory-bean="simpleAmqConnectionFactory"
   factory-method="createConnectionFactory" />
    
<bean id="connectionFactoryCached"
   class="org.springframework.jms.connection.CachingConnectionFactory"
   p:targetConnectionFactory-ref="connectionFactory"
   p:sessionCacheSize="3" />
