用jsp+mysql制作班级留言板，最好能实现图中的效果，尽量发完整代码，哪位大神会
采用纯jsp页面+Mysql的方法实现功能
项目编码是gb2312，要转换格式的请自己装换，界面简洁，功能简单，实现容易，非常适合初学者
有助于加深初学者对jsp的理解和使用Mysql数据库
String DBDRIVER = "com.mysql.jdbc.Driver";
String DBURL ="jdbc:mysql://localhost:3306/db_jsp?characterEncoding=utf-8"; //数据库名：tianming
String DBUSER = "root"; //mysql数据库用户名
String DBPASSWORD = "root"; //mysql数据库密码
功能说明：【留言内容过长的用... 代替】
权限设置：分为学生用户和管理员用户【不可直接访问页面，必须登陆后才可以进入】
普通用户的可以实现发布内容、查看内容
管理员用户的可以实现发布内容、查看内容、 删除留言、编辑留言
可以在登录页面进行注册
页面介绍：
zhuce.jsp 注册页面
login.jsp 用户登录界面
login_conf.jsp 用户登录验证
login_success.jsp 用户登录成功提示
list_notes.jsp 发布内容显示和查询结果显示页面
insert.jsp 添加新内容页面
。。。。。。。。。。。。
使用到的数据：db_jsp.sql【位于项目的web页中】
使用方法一： 使用mysql命令行： create database db_jsp;
use db_jsp;把文件内容复制粘贴到命令行即可
使用方法一： 在mysql中新建一个名为db_jsp的数据库；导入db_jsp.sql 文件即可
JSP实现留言板留言 但是我这个就只能留一个 然后 再留言就覆盖了 我怎么可以一直留下去
首先你要在result.jsp里面创建一个LinkedList, 每次按照原来的拼接message变量后,在后面也拼接上当前时间, 然后吧message加入到LinkedList变量中
index.jsp页面拿到保存在session中的LinkedList, 按照顺序打印出来就OK了
当然你的代码也可以直接改.只是顺序的问题而已
session.setAttribute("message",message) 和他下面的哪一行调换位置就行了
jsp使用session做一个留言板
网上有开源代码
关键词java 源代码 留言板应该就能出来
我记得很早以前我很容易就找到过一个
怎么样制作留言版
jsp留言板源代码1
oracle数据表创建.
create table guestbook (
lw_title varchar2(100) not null, --留言主题
lw_author varchar2(20) not null, --网上大名 pk
author_http varchar2(40) , --主页地址
author_email varchar2(40) not null,--电子信箱 pk
expression varchar2(2) not null,--表情
lw_time varchar2(14) not null,--发表回应时间
answer_num number(3) not null,--回应数
click_num number(4) not null,--点击数
author_ip varchar2(16) ,--来源ip
lw_class1 varchar2(10) not null,--留言板大类 pk
lw_class2 varchar2(20) not null,--论坛栏目 pk
lw_type varchar2(1) not null,--留言类别,即是否为主贴
zt_time varchar2(14) ,--主贴时间
zt_author varchar2(40) ,--主贴email
lw_content varchar2(4000) ,--内容
constraint pk_guestbook primary key(lw_class1,lw_class2,lw
_time,lw_author)
) storage (initial 5M next 5M pctincrease 1);

网上下的jsp源码要怎么用
需要部署到服务器中
找到菜单 window → Show View → Servers，打开Servers视图标签，部署的Tomcat 服务
在这个服务上右击，选择“Add Deployment”
在新打开的对话框中，有一个Project项，选择要部署的项目
点击“Finish”完成部署
