解决RocketMQ启动broker报错 空指针NullPointerException

解决RocketMQ启动broker报错 空指针NullPointerException

今天在部署MQ的时候，在broker-a.properties中填写了storePathRootDir 、storePathCommitLog属性的路径，然后启动beoker的时候报错了，报错信息如下

java.lang.NullPointerException
2023-12-27T07:42:54.574523199Z 	at org.apache.rocketmq.broker.schedule.ScheduleMessageService.configFilePath(ScheduleMessageService.java:271)
2023-12-27T07:42:54.574540907Z 	at org.apache.rocketmq.common.ConfigManager.persist(ConfigManager.java:82)
2023-12-27T07:42:54.574544338Z 	at org.apache.rocketmq.broker.BrokerController.shutdownBasicService(BrokerController.java:1409)
2023-12-27T07:42:54.574547705Z 	at org.apache.rocketmq.broker.BrokerController.shutdown(BrokerController.java:1484)
2023-12-27T07:42:54.574595409Z 	at org.apache.rocketmq.broker.BrokerStartup.createBrokerController(BrokerStartup.java:242)
2023-12-27T07:42:54.574615630Z 	at org.apache.rocketmq.broker.BrokerStartup.main(BrokerStartup.java:50)

然后我将storePathRootDir 以及storePathCommitLog注释了之后，发现报错没了。但是我就是想设置路径，这个参数必须要有！怎么办呢？您看下边

解决方法
**例如storePathCommitLog=/root/mq/storecommitlog 目录无需建立，删除已经建立的/root/mq/storecommitlog 目录即可

找问题的时候很烦躁，请你静下心慢慢寻找。祝你部署成功！
