Sql server 使用jTDS连接到SQL Server 2012引发IOException；MS SQL驱动程序工作正常

以下代码使用jTDS驱动程序（1.3.1）：

结果：

java.sql.SQLException: I/O Error: DB server closed connection.

我正在尝试连接到SQL Server 2012数据库。注意：用户对数据库具有只读访问权限。我无权更改SQL Server 2012上的任何配置。我曾尝试使用相同的代码连接到SQLServer2005数据库，在这种情况下，Microsoft和jTDS驱动程序都可以正常工作

如何使用jTDS毫无例外地连接到SQL Server 2012数据库？

是“anIpAddress”真正代表的只是一个IP，还是它实际上代表的是服务器上的一个命名实例，如“someserver\instance”？他们可能有一个非默认实例侦听奇数端口号，并且microsoft驱动程序正在与sql browser服务正确协商以找到该实例的侦听端口号，但jtds驱动程序没有。如果是这种情况，找出侦听端口号并显式地将其放入连接字符串应允许您在不使用sql浏览器服务的情况下进行连接。“anIpAddress”表示IP（例如216.58.218.110）。我可以使用MS SQL驱动程序显式地包含端口号1433，它仍然可以工作。如果我使用jTDS显式包含端口号，它仍然会失败。在使用sqoop中的jTDS连接到Azure DW microsoft sql server时，我面临同样的问题，并且群集已启用kerberos。。如果有人能尽快回复，那会很有帮助。。。
