管理员操作1
接下来要实现管理员对图书进行添加、删除及更新操作的功能。此处对图书信息的操作中，要在页面中输入图书信息，再将其插入到数据库中。
例如：对图书进行插入操作
addbook.jsp
<%@ page language="java" contentType="text/html; charset=gb2312"
pageEncoding="gb2312"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>添加书籍</title>
</head>
<body background=C:\Users\Administrator\Desktop\image\2.jpg>
<pre> 管理员添加书籍</pre>
<form action="insertbook.jsp" method="post" >
书名：<input type="text" name="t1"><br>
简介：<input type="text" name="t2"><br>
库存：<input type="text" name="t3"><br>
分类：<input type="text" name="t4"><br>
售价：<input type="text" name="t5"><br>
<input type="submit" name="button" value="提交">
</form>
</body>
</html>
对数据库进行插入insertbook.jsp
<%@ page language="java" contentType="text/html; charset=gb2312" import="java.sql.*"%>

<% request.setCharacterEncoding("gb2312");%>
