JAVA:用IntelliJ的思想在JSP中显示mysql数据

<%@ page import="java.sql.*" %>

    // 数据库连接信息

    // 建立数据库连接
    Connection conn = null;
    Statement stmt = null;

        conn = DriverManager.getConnection(url, username, password);
        stmt = conn.createStatement();

        // 执行查询语句
        String sql = "SELECT * FROM mytable";
        rs = stmt.executeQuery(sql);

        // 遍历结果集并显示数据
