岑泉鄅通过本文主要向大家介绍了jsp学生信息管理,jsp学生管理系统,学生信息管理系统,jsp学生信息系统,学生管理系统源代码等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
本文实例为大家分享了JSP学生信息管理系统源码,JSP+Servlet+Javabean+JDBC+MySQL,供大家参考,具体内容如下
1.service层,进行数据库操作
package com.service;

2.InputStuInfoServlet,添加学生信息的Servlet

// Put your code here
}

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

//放到Javabean中暂时保存

if(new stuInfoService().addStu(stu))//插入学生数据的方法
response.sendRedirect("../inputStuInfo_success.jsp");
else
