1、先建数据库，数据库名为：employee_DB;然后在数据库employee_DB下建表，表名为employee;最后插入数据。
create database employee_DB;
use employee_DB;
create table employee(
id int primary key auto_increment,
name varchar(50),
age int,
sex varchar(2),
salary float,
department varchar(50)
);
desc employee;
insert into employee values(1,'张雨',20,'女',3600,'后勤部');
insert into employee values(2,'刘冰',22,'男',4500,'人事');
insert into employee values(3,'张雨',25,'男',5000,'技术部');
select * from employee;
2、index.jsp页面：
1 <%@page import="java.sql.ResultSet"%>
2 <%@page import="java.sql.Statement"%>
3 <%@page import="java.sql.Connection"%>
4 <%@page import="java.sql.DriverManager"%>
5 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
6 <%
7 String path = request.getContextPath();
8 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
9 %>
