SpringBoot3整合RocketMQ问题处理

磁盘空间不够

报错如下：

org.apache.rocketmq.client.exception.MQBrokerException: CODE: 14 DESC: service not 
available now. It may be caused by one of the following reasons: the broker's disk is
 full [CL: 0.92 CQ: 0.92 INDEX: 0.92], messages are put to the slave, message store 
 has been shut down, etc. BROKER: 169.254.87.77:10911

解决办法:

1. 清理磁盘空间
2. 修改runbroker.cmd文件，增加如下内容：

set "JAVA_OPT=%JAVA_OPT% -server -Xms512m -Xmx512m -Xmn128m -Drocketmq.broker.diskSpaceWarningLevelRatio=0.99"

无法自动注入RocketMQTemplate

Field rocketMQTemplate in com.sks.crm.service.RocketMQProducerService required a bean
 of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' that could not be found.

原因：Springboot-3.0已经放弃了spring.plants自动装配，它被/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports所取代，添加这个文件是为了兼容。所以，在resources下创建META-INF，然后在META-INF下创建文件：org.springframework.boot.autoconfigure.AutoConfiguration.imports，然后在文件中添加org.apache.rocketmq.spring.autoconfigure.RocketMQAutoConfiguration即可。

RocketMQ的生产者和消费者都需要这个配置，不然有可能出现主题不存在订阅组，消费者无法监听到消息的问题。
