Description:

A component required a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' that could not be found.

The following candidates were found but could not be injected:

Action:

Consider revisiting the entries above or defining a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' in your configuration.
