网上的教程使用的都是 org.apache.commons.dbcp.BasicDataSource来作为数据库数据源，需要下载DBCP + mysql-connector jar包放到activemq/lib目录下，
并在数据库创建activemq 所需要的表。（脚本在文章尾部）

启动时却报 org.apache.commons.dbcp.BasicDataSource ClassNotFound

原因从DBCP官网下载最新的BasicDataSouce所属的包名为dbcp2 而不是dbcp，所以改完bean 的class 为 org.apache.commons.dbcp2.BasicDataSource就可以正常运行了。

另外调试方式可以使用 console 来进行调试。
