我无法使用 java 连接 SQL Server 2008 R2。相同的代码适用于 SQL Server 2005。

我试图找出 sqlserver 服务的端口和 ip，它给了我

ip - 0.0.0.0 and port 1434

我尝试使用与 SQL Server 2005 相同的连接字符串，但它在 SQL Server 2008 中对我不起作用。这是我的连接字符串：

conn=DriverManager.getConnection(jdbc:sqlserver://127.0.0.1:1434:DatabaseNameconnect?autoReconnect=true,user, password);

这是错误：

jdbc:sqlserver://127.0.0.1:1434;DatabaseName=connect;user=falcon;Password=admin
Could not connect to database

您的问题有很多可能性：

  • 防火墙
  • 没有 TCP/IP 连接器
  • 一些服务没有运行

尝试使用 SQL-management Studio 连接到您的数据库。如果这可行，请尝试通过 TCP/IP 使用 SQL-Authentification 进行连接。

一个明显的问题是 SQL Server 侦听端口 1433，而不是 1434。我已经在其他地方回答过这个问题，但我不能确定它是否与您的问题完全匹配，因为您没有告诉我们您的错误消息是什么得到。
