Answer 1

没有找到合适的驱动程序，多半是协议格式错误。粗略看了下，应该斜杠方向反了，另外还有多余的空格；然后就是注意SQLServer的版本。在sql server 2000 中加载驱动和URL路径的语句是：
String driverName = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
String dbURL = "jdbc:microsoft:sqlserver://localhost:1433; DatabaseName=sample";而sql server 2005 中加载驱动和url的语句则为：
String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String dbURL = "jdbc:sqlserver://localhost:1433; DatabaseName=sample";

Answer 2

异常说，没有合适的驱动程序来驱动你的URL首先，检查楼主是否要连接微软的SQL Server数据，驱动程序的版本是否支持现有的数据库。
其次，很有可能是数据库实例宕机、正在关闭、或已经关闭。
最后，查看一下URL是否正确。因为，我压根没用过带汉字的URL。
