使用休眠和MS SQL Server驅動程序

Question

Microsoft不向中央Maven存儲庫提供jdbc jar。 它需要手動注冊驅動程序。 但是我做錯了。 我看到了相同的異常跟蹤：

我在Maven依賴項中使用STS（eclipse產品）：

我怎么做錯了？

Answer 1

如果使用的是JRE 6.0或7.0版，請使用sqljdbc4.jar文件。 如果JRE版本是5.0，則使用sqljdbc.jar文件。

這些jar文件可以從這里下載

此外，您還可以從此處獲得有關JDBC驅動程序的系統要求的更多信息。

Answer 2

請檢查以下屬性是否正確配置

<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;database=<dbname>;</property>
    <property name="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</property>
