Answer 1

的生產者，應使用JMS連接池......通常要麼AMQ的PooledConnectionFactory或Spring的CachingConnectionFactory

對於消費者，您應該在可能的情況下使用Spring的DefaultMessageListenerContainer而不是JmsTemplate.receive（）

看到JmsTemplate的最佳做法：http://activemq.apache.org/jmstemplate-gotchas.html

和本文的詳細細節在這裏：http://codedependents.com/2009/10/16/efficient-lightweight-jms-with-spring-and-activemq/
