Question

Details about the database我是hibernate的新手。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作为数据库和SQL Server的XAMPP服务器。请帮助我传递通过休眠项目将数据发送到mysql数据库。

错误消息：

请求处理失败；嵌套的异常是org.springframework.transaction.CannotCreateTransactionException：无法打开Hibernate Session进行事务处理。嵌套的异常是org.hibernate.exception.GenericJDBCException：无法打开连接

错误说明：

服务器遇到内部错误，导致服务器无法满足此请求。

例外：

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
