String userName = "sa";   //默认用户名
String userPwd = "sa";   //密码
try {
Class.forName(driverName);
conn_sqlserver = DriverManager.getConnection(dbURL, userName, userPwd);
System.out.println("Connection Successful!");   //如果连接成功 控制台输出Connection Successful!
stmt_sqlserver=conn_sqlserver.createStatement();
} catch (Exception e) {
e.printStackTrace();
return false;
}
