基于jsp實現新聞管理系統附完整源碼

很棒的新聞發(fā)布系統分享給大家，希望大家喜歡。

下面就讓我們來說一說基于jsp的新聞發(fā)布系統，其中使用的技術有JavaBean、fillter、數據庫等，能夠實現新聞的發(fā)布功能，在發(fā)布之后能夠進行對每一條新聞的刪除、修改、或者繼續(xù)增加新的文章，最后還能夠進行查詢功能，其中引用了百度編輯器，能夠進行圖文并茂的編輯，極大地方便用戶的使用。

注：完整項目下載地址：新聞發(fā)布系統

一、效果演示

首先讓我們來看一看實現的效果：

下面是登陸的首界面：

圖1 首界面

管理員登錄頁面：

圖2 管理員登錄界面

下面是管理員登陸之后的界面，可以進行添加新聞、刪除新聞、查詢新聞：

圖3 管理員管理界面

下面是添加新聞界面，能夠進行新聞的添加：

圖4 添加新聞界面

下面是所添加的新聞：

圖5 添加后的新聞

下面是修改新聞界面：

圖6 修改新聞界面下面是修改后的界面

圖7 修改后的界面

下面是刪除新聞后的界面：

圖8 刪除新聞后的界面

對于新聞的查找，與其他類似，在這里我們使用的是利用新聞編號進行查詢所需的信息，然后在新的頁面上進行顯示。

二、具體實現過程

1、環(huán)境：編程環(huán)境為NetBeans8.0和Oracle數據庫

2、數據庫后臺的設計

在新聞管理系統中，我們需要數據庫后臺管理，其具體步驟如下所示：

根據所需的業(yè)務進行建表，可參見如下所示：建立數據庫

3、編寫步驟：

（1）首先建立以個項目，在此命名為Demo_08_NewsRealese,項目布局結構如下圖所示，根據如下布局對項目進行布局設計，方便后面的編程，項目中web-inf為項目配置文件夾，images文件夾用于儲存項目中使用的圖片文件，ueditor為百度富文本編輯器文件夾，源包文件夾為Java類文件夾：

圖9 項目布局結構圖

接著，我們進行創(chuàng)建數據庫連接層，即DAO和VO，分別存于包com.lut.beans和dao,類命名分別命名為NewsRealese、NewsRealeseDao，對于類NewsRealese而言，主要是實現字符串的包裝，其內容與數據庫里邊的內容一一對應，其代碼分別如下所示：

package com.lut.beans;
public class NewsRealese {
 private String newsId;
private String classId;
private String kindId;
private String myOther;
private String headTitle;
private String content;
private String connectRealtive;
private String author;
private String editor;
private String newsFrom;
private String top;
private String newsTime;
private String hits;
private String state;
private String tag;

 public String getNewsId() {
 return newsId;
 }

 public void setNewsId(String newsId) {
 this.newsId = newsId;
 }

 public String getClassId() {
 return classId;
 }

 public void setClassId(String classId) {
 this.classId = classId;
 }

 public String getKindId() {
 return kindId;
 }

 public void setKindId(String kindId) {
 this.kindId = kindId;
 }

 public String getMyOther() {
 return myOther;
 }

 public void setMyOther(String myOther) {
 this.myOther = myOther;
 }

 public String getHeadTitle() {
 return headTitle;
 }

 public void setHeadTitle(String headTitle) {
 this.headTitle = headTitle;
 }

 public String getContent() {
 return content;
 }

 public void setContent(String content) {
 this.content = content;
 }

 public String getConnectRealtive() {
 return connectRealtive;
 }

 public void setConnectRealtive(String connectRealtive) {
 this.connectRealtive = connectRealtive;
 }

 public String getAuthor() {
 return author;
 }

 public void setAuthor(String author) {
 this.author = author;
 }

 public String getEditor() {
 return editor;
 }

 public void setEditor(String editor) {
 this.editor = editor;
 }

 public String getNewsFrom() {
 return newsFrom;
 }

 public void setNewsFrom(String newsFrom) {
 this.newsFrom = newsFrom;
 }

 public String getTop() {
 return top;
 }

 public void setTop(String top) {
 this.top = top;
 }

 public String getNewsTime() {
 return newsTime;
 }

 public void setNewsTime(String newsTime) {
 this.newsTime = newsTime;
 }

 public String getHits() {
 return hits;
 }

 public void setHits(String hits) {
 this.hits = hits;
 }

 public String getState() {
 return state;
 }

 public void setState(String state) {
 this.state = state;
 }

 public String getTag() {
 return tag;
 }

 public void setTag(String tag) {
 this.tag = tag;
 }
 
 
}

下面是類DAO類，命名為NewsRealeseDao.java，對于DAO類，主要用于實現數據庫的連接問題，進行數據庫的鏈接，在連接過程中需要用到各種有關數據庫的技術，在這里我們使用的是Oracle數據庫，其獲取鏈接的方式為如下代碼，其中第一行為驅動程序名，第二行為數據庫地址（orcl為Oracle數據庫中的SID，在安裝Oracle數據庫時需要記?。?，第三行為具體的連接，及使用URL找到數據庫位置，然后使用密碼wjk139登錄到Scott賬戶

//獲取連接 
 Class.forName("oracle.jdbc.driver.OracleDriver"); 
 String url = "jdbc:oracle:thin:@localhost:1521:orcl"; 
conn = DriverManager.getConnection(url, "scott", "wjk139");

其他的操作分別為增刪改查的具體代碼，分別對應Servlet中或jsp中需要實例化的代碼，下面就是具體的DAO類代碼：

（2）首頁展示頁面的編寫，命名為index.html,由于可能有網絡的延遲，我們使用漸進的方式跳轉（漸進方式跳轉：window.location.href="newRealese_brief.jsp"，從index.html頁面跳轉到ewRealese_brief.jsp頁面），代碼如下所示：

!DOCTYPE html>
html>
 head>
 meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 link type="text/css" rel="stylesheet" href="newsRealese.css"/> 
 title>新聞發(fā)布系統--最前沿的時尚信息、最有看點的社會聚焦、最富得浪漫的殿堂/title>
 /head>
 body id="body">
 正在跳轉...,請等待...
 script language="javascript" type="text/javascript">
 window.location.href="newRealese_brief.jsp"; 
 /script>
 /body>

}

（5）管理員登陸之后的界面，命名為adminManager.jsp頁面，在管理員界面能夠進行刪除修改增加和查詢操作，其代碼如下所示：

（6）增加新聞頁面，命名為a_addNews.jsp，能夠進行新聞的增加，在添加完信息之后，我們點擊發(fā)布之后就可以成功添加信息，其代碼如下所示，增加新聞時需要對新聞進行編輯，對于長篇幅新聞內容且含有圖片的新聞內容的編寫，在這兒我們使用功能強大的百度編輯器，首先從官網下載：百度編輯器下載，下載之后解壓(我使用的版本是ueditor1_4_3_2-utf8-jsp)，如下圖所示結構

圖10 百度富文本編輯器文件夾結構圖

然后只需將整個文件夾拷貝到項目下即可，在使用時引入和修改路徑，在jsp頁面里邊我已經配置好引用，只需修改路徑即可，修改路徑時只需將editor_config.js中查找URL變量配置編輯器在你項目中的路徑。其中./ueditor為項目中的文件夾

var URL= window.UEDITOR_HOME_URL||"./ueditor/";

這樣就配置好了編輯器，下面就是增加新聞的jsp頁面，在添加完新聞之后，只需點擊發(fā)布即可進行新聞的發(fā)布操作，代碼如下所示：

%@page contentType="text/html" import="java.util.*,java.sql.*" pageEncoding="UTF-8" language="java"%>
%@page import="com.lut.beans.NewsRealese" %>
%@page import="dao.NewsRealeseDao" %>

在增加新聞時，需要對Servlet進行配置，如下圖所示所示為配置文件的結構：

插入數據Servlet結構圖

下面是InserOneNews.java代碼，能夠進行對數據的插入功能

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

package servlet;

import dao.NewsRealeseDao;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class InsertOneNews extends HttpServlet {
 protected void processRequest(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");
 try (PrintWriter out = response.getWriter()) {
 ArrayList addnews_list = new ArrayList();
 NewsRealeseDao newsRealeseDao = new NewsRealeseDao();
 addnews_list.add(0, request.getParameter("newsid"));
 addnews_list.add(1, request.getParameter("classid"));
 addnews_list.add(2, request.getParameter("kindid"));
 addnews_list.add(3, request.getParameter("myother"));
 addnews_list.add(4, request.getParameter("headtitle"));
 addnews_list.add(5, request.getParameter("content"));
 addnews_list.add(6, request.getParameter("connectrealtive"));
 addnews_list.add(7, request.getParameter("author"));
 addnews_list.add(8, request.getParameter("editor"));
 addnews_list.add(9, request.getParameter("newsfrom"));
 addnews_list.add(10, request.getParameter("top"));
 addnews_list.add(11, request.getParameter("newstime"));
 addnews_list.add(12, request.getParameter("hits"));
 addnews_list.add(13, request.getParameter("state"));
 addnews_list.add(14,request.getParameter("tag"));
 try {
 String newsRealese = newsRealeseDao.insertOneNews(addnews_list);
 System.out.println("String:"+newsRealese);
 if (newsRealese!= null) {
 response.sendRedirect("adminManager.jsp");
 } else {
 response.sendRedirect("a_addNews.jsp");
 }
 } catch (Exception ex) {
 Logger.getLogger(checkLogin.class.getName()).log(Level.SEVERE, null, ex);
 }
 }
 }
 @Override
 protected void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }
 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }
 @Override
 public String getServletInfo() {
 return "Short description";
 }
}

至此，我們完整的實現了插入工作（7）現在完成刪除操作，在Servlet包中建立如下所示代碼，命名為DeleteOneNews.java：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

package servlet;
import dao.NewsRealeseDao;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class DeleteOneNews extends HttpServlet {
 protected void processRequest(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");
 try (PrintWriter out = response.getWriter()) {
 String str_id=request.getParameter("newsid");
 int newsid_int=Integer.valueOf(str_id);
 NewsRealeseDao newsRealeseDao=new NewsRealeseDao();
 try {
 String newsRealese = newsRealeseDao.deleteOneNews(newsid_int);
 System.out.println("String:"+newsRealese);
 if (newsRealese!= null) {
 response.sendRedirect("adminManager.jsp");
 } else {
 response.sendRedirect("a_addNews.jsp");
 }
 } catch (Exception ex) {
 Logger.getLogger(checkLogin.class.getName()).log(Level.SEVERE, null, ex);
 }
 }
 }
 
 @Override
 protected void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }

 /**
 * Handles the HTTP code>POST/code> method.
 *
 * @param request servlet request
 * @param response servlet response
 * @throws ServletException if a servlet-specific error occurs
 * @throws IOException if an I/O error occurs
 */
 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }

 /**
 * Returns a short description of the servlet.
 *
 * @return a String containing servlet description
 */
 @Override
 public String getServletInfo() {
 return "Short description";
 }// /editor-fold>

}

(8)實現查詢操作，命名為a_queryNews.jsp,其代碼如下所示：

%-- 
 Document : a_queryNews
 Created on : 2016-5-18, 17:08:40
 Author : Administrator
--%>

%@page contentType="text/html" pageEncoding="UTF-8"%>
!DOCTYPE html>
html>
 head>
 meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 title>查詢頁面/title>
 /head>
 body>
 table style="width:100%;height:100%" border="0">
 tr>
 td>
 form action="QueryOneNews" method="post" target="_blank" >
 請輸入新聞編號：input type="text" name="query">
 input type="submit" value="查詢" >br>
 /form>
 hr>/td>
 /tr>
 tr>
 td>nbsp;/td>
 /tr>
 /table>

 /body>
/html>

對于查詢這件事，有成功，有失敗，在這兒我們進行失敗后文件的設置，代碼如下所示，命名為a_queryNewsfailed.jsp,使用超級連接的方式，連接到主頁面

%-- 
 Document : a_queryNeesfailed
 Created on : 2016-6-6, 8:43:35
 Author : Administrator
--%>

%@page contentType="text/html" pageEncoding="UTF-8"%>
!DOCTYPE html>
html>
 head>
 meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 title>查詢失敗/title>
 /head>
 body>
 h1>沒有找到你要查找的內容，但是你可以進入/h1>
 a href="index.html">主頁進行查看/a>
 /body>
/html>

實現了以上顯示層的操作之后，下面就是控制層的實現，命名為QueryOneNews.java,其代碼如下所示：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */
package servlet;
import dao.NewsRealeseDao;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class QueryOneNews extends HttpServlet {
 protected void processRequest(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 response.setContentType("text/html;charset=UTF-8");
 try (PrintWriter out = response.getWriter()) {
 String str_id=request.getParameter("query");
 int newsid_int=Integer.valueOf(str_id);
 NewsRealeseDao newsRealeseDao=new NewsRealeseDao();
 try {
 ArrayList newsRealese = newsRealeseDao.queryOneNews(newsid_int);
 char [] s1=newsRealese.toString().toCharArray();
 System.out.println("String+newsRealese:"+newsRealese);
 System.out.println("String+newsRealese:"+s1[0]+" -------"+s1[1]);
 if(s1[0]=='['s1[1]==']')
 {
 response.sendRedirect("a_queryNewsfailed.jsp");
 
 } 
 else
 {
 response.sendRedirect("newRealese_detail.jsp?newsid="+str_id); 
 } 
 } catch (Exception ex) {
 Logger.getLogger(checkLogin.class.getName()).log(Level.SEVERE, null, ex);
 }
 }
 }
 @Override
 protected void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }
 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }
 @Override
 public String getServletInfo() {
 return "Short description";
 }

}

(9)下面實現更新數據的操作，命名為a_updateNews.jsp,其代碼如下所示：

%@page contentType="text/html" import="java.util.*,java.sql.*" pageEncoding="UTF-8" language="java"%>
%@page import="com.lut.beans.NewsRealese" %>

 }
 %>

在Servlet中進行如下代碼所示配置：

/*
 * To change this license header, choose License Headers in Project Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

package servlet;

import dao.NewsRealeseDao;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class UpdateOneNews extends HttpServlet {

 try (PrintWriter out = response.getWriter()) {

 NewsRealeseDao newsRealeseDao = new NewsRealeseDao();
 addnews_list.add(0, request.getParameter("newsid"));
 addnews_list.add(1, request.getParameter("classid"));
 addnews_list.add(2, request.getParameter("kindid"));
 addnews_list.add(3, request.getParameter("myother"));
 addnews_list.add(4, request.getParameter("headtitle"));

 try {
 String newsRealese = newsRealeseDao.updateOneNews(addnews_list);
 System.out.println("String:"+newsRealese);
 if (newsRealese!= null) {
 response.sendRedirect("adminManager.jsp");
 } else {
 response.sendRedirect("a_addNews.jsp");
 }
 } catch (Exception ex) {
 Logger.getLogger(checkLogin.class.getName()).log(Level.SEVERE, null, ex);
 }
 }
 }
 @Override
 protected void doGet(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {
 processRequest(request, response);
 }
 @Override
 protected void doPost(HttpServletRequest request, HttpServletResponse response)
 throws ServletException, IOException {

 }
 @Override
 public String getServletInfo() {
 return "Short description";
 }
}

到這兒，我們已經實現了對增刪改查功能的實現，當然，基本的新聞發(fā)布功能已經實現
