连接数据库出现问题

[Sun灼0_o]

错误如下：
com.microsoft.sqlserver.jdbc.SQLServerException: 通过端口 1433 连接到主机 localhost 的 TCP/IP 连接失败。错误:“Connection refused: connect。请验证连接属性。确保 SQL Server 的实例正在主机上运行，且在此端口接受 TCP/IP 连接，还要确保防火墙没有阻止到此端口的 TCP 连接。”。

代码如下：
String sDBDriver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
String sConnStr = "jdbc:sqlserver://localhost:1433;DatabaseName=ST";

String userName = "tardis";

String userPwd = "1234";

Connection conn = null;
ResultSet rs = null;

try {
Class.forName(sDBDriver);
}catch(java.lang.ClassNotFoundException e)
{
System.err.println("faq(): " + e.getMessage());
}

conn = DriverManager.getConnection(sConnStr,userName,userPwd);
Statement stmt = conn.createStatement();


String sql = "select * from student";
rs = stmt.executeQuery(sql);
搜索很多方案依然没有作用。

直接修改sqlserver的配置管理ip协议修改就好了

如果是 sqlserver2005 要确定tcp/ip开的端口是1433，不要用动态端口。 sql server配置允许远程连接。
