私信源码获取及调试交流

私信源码获取及调试交流

运行环境

Java≥8、MySQL≥5.7、Tomcat≥8

开发工具

eclipse/idea/myeclipse/sts等均可配置运行

适用

课程设计，大作业，毕业设计，项目练习，学习演示等

功能说明

基于javaweb的JSP+Servlet网上图书馆管理系统(java+jsp+servlert+mysql+ajax)

一、项目简述

功能： 区分为管理员用户和普通用户，普通用户：用户登录，个 人信息修改，图书查询，用户借阅，用户归还，管理员用 户：图书馆里，归还管理，借阅信息查询，图书维护，分 类管理，读者管理等等功能。

二、项目运行

环境配置： Jdk1.8 + Tomcat8.5 + mysql + Eclispe (IntelliJ IDEA,Eclispe,MyEclispe,Sts 都支持)

项目技术： JSP + Servlert + html+ css + JavaScript + JQuery + Ajax等等。

			//还书在管理员和读者界面都有，为了区分，设置了show字段，show为1表示读者界面
			int show = Integer.parseInt(request.getParameter("show"));
			//调用还书函数，改变status字段
			bookdao.borrowBook2(hid);
			if (show==1) {
				response.sendRedirect("borrow.jsp");
			} else {
				response.sendRedirect("admin_borrow.jsp");
			}
