你这是桥连接？

发一下代码～

public class DAOConnection {
public static Connection conn(){
Connection con = null;
try {
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
con = DriverManager.getConnection("jdbc:sqlserver://127.0.0.1:1433;DatabaseName=DVDground","sa", "123456");
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return con;
}
public static void close(ResultSet rs){
if(rs != null){
try {
rs.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Statement stmt){
if(stmt != null){
try {
stmt.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void close(Connection conn){
if(conn != null){
try {
conn.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}

你检查一下端口号，是不是1433然后再看看你SQLServer的用户名和密码是否正确

还有，检查sqlserver服务是否开启
