用jsp+mysql製作班級留言板，最好能實現圖中的效果，盡量發完整代碼，哪位大神會

採用純jsp頁面+Mysql的方法實現功能

項目編碼是gb2312，要轉換格式的請自己裝換，界面簡潔，功能簡單，實現容易，非常適合初學者

有助於加深初學者對jsp的理解和使用Mysql數據庫

String DBDRIVER = “com.mysql.jdbc.Driver”;

String DBURL =”jdbc:mysql://localhost:3306/db_jsp?characterEncoding=utf-8″; //數據庫名：tianming

String DBUSER = “root”; //mysql數據庫用戶名

String DBPASSWORD = “root”; //mysql數據庫密碼

功能說明：【留言內容過長的用… 代替】

權限設置：分為學生用戶和管理員用戶【不可直接訪問頁面，必須登陸後才可以進入】

普通用戶的可以實現發佈內容、查看內容

管理員用戶的可以實現發佈內容、查看內容、 刪除留言、編輯留言

可以在登錄頁面進行註冊

頁面介紹：

zhuce.jsp 註冊頁面

login.jsp 用戶登錄界面

login_conf.jsp 用戶登錄驗證

login_success.jsp 用戶登錄成功提示

list_notes.jsp 發佈內容顯示和查詢結果顯示頁面

insert.jsp 添加新內容頁面

。。。。。。。。。。。。

使用到的數據：db_jsp.sql【位於項目的web頁中】

使用方法一： 使用mysql命令行： create database db_jsp;

use db_jsp;把文件內容複製粘貼到命令行即可

使用方法一： 在mysql中新建一個名為db_jsp的數據庫；導入db_jsp.sql 文件即可

JSP實現留言板留言 但是我這個就只能留一個 然後 再留言就覆蓋了 我怎麼可以一直留下去

首先你要在result.jsp裏面創建一個LinkedList, 每次按照原來的拼接message變量後,在後面也拼接上當前時間, 然後吧message加入到LinkedList變量中

index.jsp頁面拿到保存在session中的LinkedList, 按照順序打印出來就OK了

當然你的代碼也可以直接改.只是順序的問題而已

session.setAttribute(“message”,message) 和他下面的哪一行調換位置就行了

jsp使用session做一個留言板

網上有開源代碼

關鍵詞java 源代碼 留言板應該就能出來

我記得很早以前我很容易就找到過一個

怎麼樣製作留言版

jsp留言板源代碼1

oracle數據表創建.

create table guestbook (

lw_title varchar2(100) not null, –留言主題

lw_author varchar2(20) not null, –網上大名 pk

author_http varchar2(40) , –主頁地址

author_email varchar2(40) not null,–電子信箱 pk

expression varchar2(2) not null,–表情

lw_time varchar2(14) not null,–發表回應時間

answer_num number(3) not null,–回應數

click_num number(4) not null,–點擊數

author_ip varchar2(16) ,–來源ip

lw_class1 varchar2(10) not null,–留言板大類 pk

lw_class2 varchar2(20) not null,–論壇欄目 pk

lw_type varchar2(1) not null,–留言類別,即是否為主貼

zt_time varchar2(14) ,–主貼時間

zt_author varchar2(40) ,–主貼email

lw_content varchar2(4000) ,–內容

constraint pk_guestbook primary key(lw_class1,lw_class2,lw

_time,lw_author)

) storage (initial 5M next 5M pctincrease 1);

網上下的jsp源碼要怎麼用

需要部署到服務器中

找到菜單 window → Show View → Servers，打開Servers視圖標籤，部署的Tomcat 服務

在這個服務上右擊，選擇「Add Deployment」

在新打開的對話框中，有一個Project項，選擇要部署的項目

點擊「Finish」完成部署

這樣項目就部署到Tomcat裏面去了
