JSP实现数据库（MySQL）查询——Java Web练习（二）

1.创建数据库表student(数据库test01)

2.修改success.jsp页面，修改后的页面整体代码如下：

<%@ page language="java" import="java.sql.*,java.io.*,java.util.*"
    pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
