ActiveMQ的各种表SQL的管理

      在ActiveMQ为了方便的切换数据库，更为了深入了解ActiveMQ中SQL语句的详细的信息,可以通过Statements获取各种SQL语句。在ActivMQ第一次加载的时候，通过Statements生产响应的Spring Bean，加载到内存中。在ActiveMQ的管理和监控的时候，从内容获取相关的SQL语句，简化了ActiveMQ的消息的管理和监控。

你好，我想陪着在mq中配置statements改变MSGS的类型为varchar。请问如何配置。还有。这样配置会不会提高数据库的持久化的性能。目前数据库持久化性能很低。不知什么原因。谢谢
