RocketMQ啟動失敗

Field rocketMQTemplate in com.xxx.demo.rocketmq.ProducerService required a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' that could not be found.

參考ISSUE98

# 錯誤配置
spring:
    rocketmq:
        name-server: xxxxx
        producer:
            group:xxxxxx


# 正確配置
spring:
    redis:
        database: 0
        host: localhost
        ........
rocketmq:
  name-server: 172.16.21.138:9876
  producer:
    group: short-message

注意rocketmq應該和spring同個級別，因此在application.properties中的配置應該為：

# 錯誤配置
spring.rocketmq.name-server=127.0.0.1:9876
spring.rocketmq.producer.group=producer

# 正確配置
rocketmq.name-server=127.0.0.1:9876
rocketmq.producer.group=producer

開發過程中遇到的另一個問題是RocketMQTemplate無法使用，雖然.m2/repository文件夾中包含這個包，但是引用時爆紅，解決方法如下：
