Answer 1

也许你是Java的新手！我认为您需要在http://www.microsoft.com/en-us/download/details.aspx?displaylang=en&id=11774下载JDBC驱动程序。之后解压缩下载的文件以获取.jar个文件。最后将sqljdbc.jar或sqljdbc4.jar复制到类路径以修复错误。

Answer 2

类com.microsoft.jdbc.sqlserver.SQLServerDriver不在您的JRE类路径中。

可在sqljdbc.jar文件中找到，该文件应添加到您的类路径中。

为什么我收到SQLServerDriver的ClassNotFoundException？
