BookBean book = bookdao.searchBook(bookid);

if(book!=null){

request.getSession().setAttribute(\

RequestDispatcher view = request.getRequestDispatcher(\ view.forward(request, response); }else{

RequestDispatcher view = request.getRequestDispatcher(\ view.forward(request, response); } } }

【步骤8】下面的Servlet实现向数据库插入数据，并将控制请求的转发到bookInsert.jsp页面。

package com.control;

import java.io.*; import java.sql.*; import javax.servlet.*; import javax.servlet.http.*; import com.beans.BookBean; import com.beans.BookDAO;

public class BookInsertServlet extends HttpServlet{

public void doPost(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException{

request.setCharacterEncoding(\ String message = null;

BookBean book = new BookBean(

request.getParameter(\ request.getParameter(\ Float.parseFloat(request.getParameter(\ );
