1、在《ActiveMQ 基于zookeeper的主從（levelDB Master/Slave）搭建以及Spring-boot下使用》中，采用以下代碼進行JMS消息發送：

|
@Servicepublic class Producer { @Autowired private JmsMessagingTemplate jmsTemplate; public void sendMessage(Destination destination, final String message){ jmsTemplate.convertAndSend(destination, message); }} |
經使用JMeter進行壓力測試，發現JMS的發送消息特別慢。
2、下面通過自定義CachingConnectionFactory解決。
