Java Spring Hibernate应用程序: Could not open connection

Question

我正在使用 mssql 数据库开发 java Spring Hibernate 应用程序。但我无法与 mssql 数据库建立连接。

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

我的applicationContext.xml如下:

Answer 1

您正在使用 Microsoft SQL Server 驱动程序和 MySQL 方言。

对 Microsoft SQL Server 使用org.hibernate.dialect.SQLServerDialect。
