我想将Java类文件与SQL Server 2012连接.我已经使用SQL Server身份验证登录.但我收到连接错误.
错误:与主机127.0.0.1,端口1433的TCP/IP连接失败.错误:"连接被拒绝:连接.验证连接属性.确保主机上正在运行SQL Server实例并接受端口上的TCP/IP连接.确保防火墙不阻止与端口的TCP连接".
我的代码---
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); //1. Register your driver
//2. get the connection object
//Connection con = DriverManager.getConnection("jdbc:sqlserver://localhost;databaseName=aysha","sa","admin");
Connection con = DriverManager.getConnection("jdbc:sqlserver://127.0.0.1;databaseName=aysha","user=sa","password=admin");
//"jdbc:sqlserver://127.0.0.1:1433; Instance=SQL2008;" + "databaseName=MB;user=sa;password=123;";
//Connection con = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=aysha","sa" , "password");
//3. Prepare a statement
Statement stmt = con.createStatement();
//4. Write the query`
String sql = "Select * from employee";
//5. Execute the statement and
ResultSet rs = stmt.executeQuery(sql);
//6. Process the result set
while (rs.next())
{
System.out.println(rs.getInt(1));
}
