org.apache.tomcat.dbcp.dbcp.BasicDataSource强制转换失败问题

我是一条酸菜魚 2016-03-23 05:05:24

获取数据库连接池的时候，强制转换BasicDataSource ds = (BasicDataSource)OaPubSQLManager.ds;结果报错org.apache.tomcat.dbcp.dbcp.BasicDataSource cannot be cast to org.apache.tomcat.dbcp.dbcp.BasicDataSource
数据库配置没有问题，是一直都运行的项目，是否我jar包引用的问题，请大神指教
