Question

以下代码使用jTDS驱动程序（1.3.1）：

DriverManager.getConnection("jdbc:jtds:sqlserver://anIpAddress;databaseName=aDatabase", "user", "pass")

结果：

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

    at net.sourceforge.jtds.jdbc.TdsCore.login(TdsCore.java:632)

但是，使用MS SQL驱动程序（4.2）的此代码无例外地工作：

DriverManager.getConnection("jdbc:sqlserver://anIpAddress;databaseName=aDatabase", "user", "pass")

我正在尝试连接到SQL Server 2012数据库。注意：用户具有对数据库的只读访问权限。我无权更改SQL Server 2012上的任何配置。我尝试使用相同的代码连接到SQL Server 2005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？

使用jTDS连接到SQL Server 2012会抛出IOException; MS SQL驱动程序有效
