关于数据库的详细信息我对hibernate不熟悉。我创建了一个hibernate项目。但是它无法连接到mysql数据库。我使用sql workbench作为数据库，使用xampp服务器作为sql服务器。请帮助我通过hibernate项目将数据传递到mysql数据库。
错误消息：
请求处理失败；嵌套异常为org.springframework.transaction.cannotcreatetransactionexception:无法打开事务的hibernate会话；嵌套异常为org.hibernate.exception.genericjdbception:无法打开连接
错误描述：
服务器遇到内部错误，无法完成此请求。
例外情况：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection
