请问哪里错了？能编译但是没结果

public class Test03 {
    public static void main(String[] args) {

        ResourceBundle bundle = ResourceBundle.getBundle("jdbc");
        String driver = bundle.getString("driver");
        String url = bundle.getString("url");
        String user = bundle.getString("user");
        String password = bundle.getString("password");

        Statement stmt = null;
        Connection conn = null;
        try {
            //1.
            Class.forName("driver");
            //2.
            conn = DriverManager.getConnection(url, user, password);
            System.out.println(conn);
            //3.
            stmt = conn.createStatement();
            //4.
            int count = stmt.executeUpdate("insert into t_student(no,name,sex) values(2,'555',3)");
            System.out.println(count == 1 ? "保存成功" : "保存失败");
            //5.

            //6.
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            if (stmt != null) {
                try {
                    stmt.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
            if (conn != null) {
                try {
                    conn.close();
                } catch (SQLException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

结果：

java.lang.ClassNotFoundException: driver
    at java.net.URLClassLoader.findClass(URLClassLoader.java:382)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:418)

配置文件：

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/linf
user=root

已经知道原因啦

Class.forName("driver")？？？？ 况且因为JAVA的SPI机制，现在已经不需要手动加载Driver驱动了。有兴趣可以了解一下SPI
