基于jsp实现新闻管理系统 附完整源码

作者：suwu150

这篇文章主要介绍了基于jsp的新闻管理系统,具有一定的参考价值，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

很棒的新闻发布系统分享给大家，希望大家喜欢。

下面就让我们来说一说基于jsp的新闻发布系统，其中使用的技术有JavaBean、fillter、数据库等，能够实现新闻的发布功能，在发布之后能够进行对每一条新闻的删除、修改、或者继续增加新的文章，最后还能够进行查询功能，其中引用了百度编辑器，能够进行图文并茂的编辑，极大地方便用户的使用。

注：完整项目下载地址：新闻发布系统

一、效果演示

首先让我们来看一看实现的效果：

下面是登陆的首界面：

图1 首界面

管理员登录页面：

图2 管理员登录界面

下面是管理员登陆之后的界面，可以进行添加新闻、删除新闻、查询新闻：

图3 管理员管理界面

下面是添加新闻界面，能够进行新闻的添加：

图4 添加新闻界面

下面是所添加的新闻：

图5 添加后的新闻

下面是修改新闻界面：

图6 修改新闻界面下面是修改后的界面

图7 修改后的界面

下面是删除新闻后的界面：

图8 删除新闻后的界面

对于新闻的查找，与其他类似，在这里我们使用的是利用新闻编号进行查询所需的信息，然后在新的页面上进行显示。

二、具体实现过程 

1、环境：编程环境为NetBeans8.0和Oracle数据库 

2、数据库后台的设计   

在新闻管理系统中，我们需要数据库后台管理，其具体步骤如下所示：

根据所需的业务进行建表，可参见如下所示：建立数据库

3、编写步骤：

（1）首先建立以个项目，在此命名为Demo_08_NewsRealese,项目布局结构如下图所示，根据如下布局对项目进行布局设计，方便后面的编程，项目中web-inf为项目配置文件夹，images文件夹用于储存项目中使用的图片文件，ueditor为百度富文本编辑器文件夹，源包文件夹为Java类文件夹：

图9 项目布局结构图

接着，我们进行创建数据库连接层，即DAO和VO，分别存于包com.lut.beans和dao,类命名分别命名为NewsRealese、NewsRealeseDao，对于类NewsRealese而言，主要是实现字符串的包装，其内容与数据库里边的内容一一对应，其代码分别如下所示： 

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;
 }
 
 
}

下面是类DAO类，命名为NewsRealeseDao.java，对于DAO类，主要用于实现数据库的连接问题，进行数据库的链接，在连接过程中需要用到各种有关数据库的技术，在这里我们使用的是Oracle数据库，其获取链接的方式为如下代码，其中第一行为驱动程序名，第二行为数据库地址（orcl为Oracle数据库中的SID，在安装Oracle数据库时需要记住），第三行为具体的连接，及使用URL找到数据库位置，然后使用密码wjk139登录到Scott账户 

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

其他的操作分别为增删改查的具体代码，分别对应Servlet中或jsp中需要实例化的代码，下面就是具体的DAO类代码：

package dao;

import com.lut.beans.NewsRealese;

（2）首页展示页面的编写，命名为index.html,由于可能有网络的延迟，我们使用渐进的方式跳转（渐进方式跳转：window.location.href="newRealese_brief.jsp"，从index.html页面跳转到ewRealese_brief.jsp页面），代码如下所示： 

<!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>新闻发布系统--最前沿的时尚信息、最有看点的社会聚焦、最富得浪漫的殿堂</title>
 </head>
 <body id="body">
 正在跳转...,请等待...
 <script language="javascript" type="text/javascript">
 window.location.href="newRealese_brief.jsp"; 
 </script>
 </body>
</html>

在缓冲时，会进行跳转，跳转后的页面为newRealese_brief.jsp,其代码如下所示：进入新闻展示页面之后，我们能够对新闻进行搜素，还能够查看详细内容。

（4）管理员登录界面，命名为adminLogin.jsp页面，使用连接数据库的方式进行登录，在这里我们的管理员名称为Scott，密码为wjk139，管理员登录界面的实现代码如下所示 

<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>


<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>新闻发布系统--最前沿的时尚信息、最有看点的社会聚焦、最值得浪漫的殿堂</title>
<link type="text/css" rel="stylesheet" href="newsRealese.css"/> 
</head>
 <body id="body">
 <form method="post" action="checkLogin">
 <table border="0" align="center" id="table_vertical" >
 <caption>管理员登录 </caption>
 <tr>
 <td width="40">Admin</td>
 <td width="183">
 <input type="text" name="user"></td>
 </tr>
 <tr>
 <td height="25">Pass</td>
 <td><input type="password" name="pass"></td>
 </tr>
 </table> 
 <table align="center">
 <tr>
 <td>
 <input type="submit" value="Login">
 <input type="reset" value="Reset">
 </td>
 </tr> 
 </table>
</form>
</body>
</html>

在登录的过程中，我们需要进行判断，命名为checkLogin.java,，通过此类进行判断登录是否成功，若成功，则跳转到管理界面，若失败，则停留在当前界面，其代码如下所示：

 throws ServletException, IOException {
 processRequest(request, response);
 }

 @Override
 public String getServletInfo() {
 return "Short description"+"public String getServletInfo() ";
 }// </editor-fold>
}

（5）管理员登陆之后的界面，命名为adminManager.jsp页面，在管理员界面能够进行删除修改增加和查询操作，其代码如下所示：

</html>

（6）增加新闻页面，命名为a_addNews.jsp，能够进行新闻的增加，在添加完信息之后，我们点击发布之后就可以成功添加信息，其代码如下所示，增加新闻时需要对新闻进行编辑，对于长篇幅新闻内容且含有图片的新闻内容的编写，在这儿我们使用功能强大的百度编辑器，首先从官网下载：百度编辑器下载，下载之后解压(我使用的版本是ueditor1_4_3_2-utf8-jsp)，如下图所示结构

图10 百度富文本编辑器文件夹结构图

然后只需将整个文件夹拷贝到项目下即可，在使用时引入和修改路径，在jsp页面里边我已经配置好引用，只需修改路径即可，修改路径时只需将editor_config.js中查找URL变量配置编辑器在你项目中的路径。其中./ueditor为项目中的文件夹 

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

这样就配置好了编辑器，下面就是增加新闻的jsp页面，在添加完新闻之后，只需点击发布即可进行新闻的发布操作，代码如下所示： 

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

 </head>
 <body id="body">
 <form action="InsertOneNews" method="post">
 <table border="0" id="table">

 <td width="5%">left</td>
 <td width="90%"> 
 <table border="1" id="table">

 <td>所属新闻栏目编号</td> <td><input type="text" name="classid"></td>
 </tr>
 <tr>
 <td>所属新闻分类编号</td> <td><input type="text" name="kindid"></td>
 <td>原创或转载</td> <td><input type="text" name="myother"></td>
 </tr>
 <tr>
 <td>新闻标题</td> <td><input type="text" name="headtitle"></td>

 </tr>
 <tr>

 </table>
 </td>
 <td width="5%">right</td>
 </tr>
 <tr>
 <td>&nbsp;</td>
 <td>
 <div align="center" style="width:80%"> 
 <textarea id="newsEditor" name="content" style="height: 80%"></textarea> 
 <br/> 
 <input type="submit" value="发 布"> 
 <script type="text/javascript">
 UE.getEditor('newsEditor');
 // var content = UE.getPlainTxt();//content就是编辑器的带格式的内容
 //focus时自动清空初始化时的内容

 </script> 
 </div>

 </td>
 <td>&nbsp;</td>
 </tr>
 </table> 
 </form>
 </body>
</html>

在增加新闻时，需要对Servlet进行配置，如下图所示所示为配置文件的结构： 

插入数据Servlet结构图

下面是InserOneNews.java代码，能够进行对数据的插入功能 

/*
 * 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，我们完整的实现了插入工作 （7）现在完成删除操作，在Servlet包中建立如下所示代码，命名为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)实现查询操作，命名为a_queryNews.jsp,其代码如下所示：

<%-- 
 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>查询页面</title>
 </head>
 <body>
 <table style="width:100%;height:100%" border="0">
 <tr>
 <td>
 <form action="QueryOneNews" method="post" target="_blank" >
 请输入新闻编号：<input type="text" name="query">
 <input type="submit" value="查询" ><br>
 </form>
 <hr></td>
 </tr>
 <tr>
 <td>&nbsp;</td>
 </tr>
 </table>

 </body>
</html>

对于查询这件事，有成功，有失败，在这儿我们进行失败后文件的设置，代码如下所示，命名为a_queryNewsfailed.jsp,使用超级连接的方式，连接到主页面 

<%-- 
 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>查询失败</title>
 </head>
 <body>
 <h1>没有找到你要查找的内容，但是你可以进入</h1>
 <a href="index.html">主页进行查看</a>
 </body>
</html>

实现了以上显示层的操作之后，下面就是控制层的实现，命名为QueryOneNews.java,其代码如下所示：

/*
 * 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)下面实现更新数据的操作，命名为a_updateNews.jsp,其代码如下所示：

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

 int news_int=Integer.valueOf(newsid_s);
 
 ArrayList news_list=newsRealeseDao.queryOneNews(news_int);
 %>
 <%
 for(int i=0;i<news_list.size();i++)
 {
 NewsRealese newRealese=(NewsRealese)news_list.get(i); 
 %>
 <form action="UpdateOneNews" method="post">

 </script> 
 </div> 
 </td>
 <td>&nbsp;</td>
 </tr>
</table> 
 </form>
 <%
 }
 %>
</body>
</html>

在Servlet中进行如下代码所示配置：

/*
 * 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 {
 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.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 {
 processRequest(request, response);
 }
 @Override
 public String getServletInfo() {
 return "Short description";
 }
}

到这儿，我们已经实现了对增删改查功能的实现，当然，基本的新闻发布功能已经实现
