# # configuration file rocketmq: name-server: 192.168.2.182 rocketmq 9876 * ExtNameServer: 192.168.2.182 public class ExtRocketMQTemplate extends RocketMQTemplate 9876 Java Code@ExtRocketMQTemplateConfiguration (nameServer = "${demo.rocketmq.extNameServer}") Problem description

Stack information is posted:
