java - 使用 hibernate 和 ms sql server 驱动程序

Question

Microsoft 不向中央 Maven 存储库提供 jdbc jar。它需要手动注册驱动程序。但我做错了什么。我看到了相同的异常跟踪:

我使用STS(eclipse产品)在 Maven 依赖项中:

我做错了什么？

Answer 1

如果您使用 JRE 版本 6.0 或 7.0，则使用 sqljdbc4.jar 文件。如果JRE版本是5.0，则使用sqljdbc.jar文件。

这些jar文件可以从here下载

此外，您还可以从 here 更清楚地了解 JDBC 驱动程序的系统要求。
