java - 连接到 Microsoft SQL Server 时出错

Question

我尝试从 java 连接到 MS SQL Server 2005，但收到以下错误，谁能帮我吗？

private static final String DRIVER_CLASS = "com.microsoft.jdbc.sqlserver.SQLServerDriver"; 
Class.forName(DRIVER_CLASS); 
DriverManager.getConnection("jdbc:sqlserver://localhost:1433","sa","root");

我添加了以下 5 个 jar 文件:

• 微软数据库
• mssql服务器
• msutil
• sqljdbc
• sqljdbc4

异常(exception)是:

java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.

你的防火墙打开了吗？如果是这样，也许您需要对端口 1433 进行异常(exception)处理
