try {
connection = DriverManager.getConnection(
"jdbc:sqlserver://127.0.0.1;DatabaseName=StudentGrade",
"sa", "123456");

CallableStatement call = connection
.prepareCall("{call proc_DemoLogin(?,?)}"); //proc_DemoLogin 你写好的存储过程名字
call.setString(1, username); //参数设置
call.setString(2, pwd);
ResultSet resultSet = call.executeQuery();
if (resultSet.next()) {
return resultSet.getString(1);

} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
