如何解决；登录失败"；错误（JDBC Java），仅在Windows身份验证的两种情况之一失败

我有Java代码，它使用JDBC连接到我公司的两个数据库。管理员将这两个权限都授予我作为Windows自动验证。我可以使用SQL Server Management Studio完美地连接两个数据库并与之交互。问题是，我只能使用java中JDBC的第一个数据库，因为尝试连接到第二个数据库会导致“无法打开数据库”错误

这很奇怪，因为我可以完美地处理第一个数据库，而两个数据库的主服务器是相同的。我有JDBC驱动程序和Windows身份验证所需的

sqljdbc_auth.dll

文件。我使用模块化方法来避免类型错误。以下是代码（出于安全原因，我在XXX中更改了一些字符）：

预期结果是两个数据库的连接都正确。但是，只有第一个连接成功，并且打印从数据库表获得的值，而第二个连接失败，如控制台输出所示：

问题似乎是与第二台服务器的特定数据库SISECPrueba的连接，因为服务器实例是正确的

---

最后，正如我前面提到的，我可以使用windows应用程序SQL Server Management Studio正常访问这两台服务器。

尝试修改方法

公共连接startSQLconnection（字符串URL）抛出异常{return DriverManager.getConnection（URL）；}

并将连接保存到不同的变量

connection1

和

connection2

“两个数据库的主服务器是相同的”，这实际上并不相关：它们是两个不同的SQL server实例，可以具有不同的配置。它们托管在同一台计算机上的事实并不能改变这两台SQL Server是不同的事实。@MarkrotVeel感谢您的澄清：D@Max，我按照你的建议做了，但遗憾的是，没有成功：（，错误保持不变。我升级了问题中的上述代码。实际上代码是相同的。两个SQL Server服务用户是相同的？如果颠倒连接顺序，结果是相同的？
