使用官方提供的rocketmq-spring-boot-starter提供的例子写ExtRocketMQTemplate时候，修改了配置文件中的nameServer配置，改成了和rocketmq.name-server一样的值：
## 配置文件
rocketmq:
name-server: 192.168.2.182:9876;192.168.2.183:9876
...
demo:
rocketmq:
...
extNameServer: 192.168.2.182:9876;192.168.2.183:9876
## Java Code
@ExtRocketMQTemplateConfiguration(nameServer = "${demo.rocketmq.extNameServer}")
public class ExtRocketMQTemplate extends RocketMQTemplate {
}贴上了堆栈信息：
org.springframework.beans.factory.support.BeanDefinitionValidationException: Bad annotation definition in @ExtRocketMQTemplateConfiguration, nameServer property is same with global property, please use the default RocketMQTemplate! at org.apache.rocketmq.spring.autoconfigure.ExtProducerResetConfiguration.validate(ExtProducerResetConfiguration.java:153) ~[rocketmq-spring-boot-2.0.3.jar:2.0.3] at org.apache.rocketmq.spring.autoconfigure.ExtProducerResetConfiguration.registerTemplate(ExtProducerResetConfiguration.java:88) ~[rocketmq-spring-boot-2.0.3.jar:2.0.3] at java.util.LinkedHashMap.forEach(LinkedHashMap.java:684) ~[na:1.8.0_144] at org.apache.rocketmq.spring.autoconfigure.ExtProducerResetConfiguration.afterSingletonsInstantiated(ExtProducerResetConfiguration.java:75) ~[rocketmq-spring-boot-2.0.3.jar:2.0.3] ...
根据报错提示，nameServer不能设置为和上面rocketmq.name-server一样的值，改为不一样即可解此问题：
rocketmq: name-server: 192.168.2.182:9876;192.168.2.183:9876 ... # properties used in the application demo: rocketmq: ... extNameServer: 192.168.2.182:9876
