[英]ActiveMQ - JDBC persistence MySQL: ACTIVEMQ_MSGS is empty
I'm implement the persistence with MySQL ( http://activemq.apache.org/jdbc-support.html ). 我正在使用MySQL( http://activemq.apache.org/jdbc-support.html )实现持久性。 But when I check this table, it's always empty. 但是当我检查此表时,它总是空的。

Could you please help me fixing this problem? 您能帮我解决这个问题吗?
Thanks, 谢谢,
For the persistent adapter to work remove , the dataDirectory
from the <broker>
& <jdbcPersistenceAdapter>
tags. 为了使持久适配器正常工作, dataDirectory
从<broker>
和<jdbcPersistenceAdapter>
标记中<jdbcPersistenceAdapter>
。 This way the kahaDb won't be initialised. 这样就不会初始化kahaDb。
