新闻发布系统

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。

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：

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;
import static java.lang.System.out;

        try {

            String url = "jdbc:oracle:thin:@localhost:1521:orcl";
            conn = DriverManager.getConnection(url, "scott", "wjk139");
            //运行SQL语句 
            String sql = "select * from newmessage";//获取
            Statement stat = conn.createStatement();
            ResultSet rs = stat.executeQuery(sql);
            while (rs.next()) {   //实例化VO
                NewsRealese news = new NewsRealese();
                news.setNewsId(rs.getString("newsid"));

<!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。

              </tr>
              <tr>

          </tr>      
      </table>   
    </td>
  </tr>
</table>

</table>
                  <%
            }
            %>
</body>
</html>

（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：

/*

package servlet;

import com.lut.beans.NewsRealese;
import dao.NewsRealeseDao;
import java.io.IOException;
import java.io.PrintWriter;
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 checkLogin extends HttpServlet {
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        String user=request.getParameter("user");
        String pass=request.getParameter("pass");
          NewsRealeseDao newsRealeseDao=new NewsRealeseDao();
        try {    
            String newsRealese=newsRealeseDao.ischecked(user,pass);
             if(newsRealese!=null)
             {
                 response.sendRedirect("adminManager.jsp");
             }
             else
             {
                 response.sendRedirect("adminLogin.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"+"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：

<%-- 
    Document   : adminManager
    Created on : 2016-5-18, 17:10:01

                                    ArrayList newsRealese = newsRealeseDao.queryAllNews();
                                %>

（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，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" %>

                            <tr>
                                <td>新闻状态</td> <td><input type="text" name="state"></td>

                            </tr>
                            <tr>

                        </table>
                    </td>
                    <td width="5%">right</td>
                </tr>
                <tr>
                    <td> </td>
                    <td>

                                // 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> </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 template file, choose Tools | Templates
 * and open the template in the editor.

                if (newsRealese!= null) {
                    response.sendRedirect("adminManager.jsp");
                } else {

     * 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> </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" %>
<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>更改新闻-</title>
    <!-- 配置文件 -->
    <script type="text/javascript" src="./ueditor/ueditor.config.js"></script>
    <!-- 编辑器源码文件 -->
    <script type="text/javascript" src="./ueditor/ueditor.all.js"></script>
    <link rel="stylesheet" type="text/css" href="./udeditor/themes/default/css" />
    <link type="text/css"  rel="stylesheet"  href="newsRealese.css"/>
    </head>
 <body id="body">
     <%
         NewsRealeseDao newsRealeseDao=new NewsRealeseDao();
         String newsid_s=request.getParameter("newsid");
         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">
     <table  border="0" id="table" style="width:95%">
  <tr>
    <td width="5%">left</td>
    <td width="90%">    
        <table  border="1" id="table" style="width:100%">
            <tr >       
            <tr>
                <td >新闻编号</td> <td><input  type="text"  width="100%" name="newsid" value="<%=newRealese.getNewsId()  %>"></td>

                <td>原创或转载</td> <td><input type="text" width="100%" name="myother" value="<%=newRealese.getMyOther()  %>"></td>
			</tr>
			<tr>
                            <td>新闻标题</td> <td><input type="text" width="100%" name="headtitle" value="<%=newRealese.getHeadTitle()%>"></td>
                <td>相关文章</td> <td><input type="text" width="100%" name="connectrealtive"  value="<%=newRealese.getConnectRealtive()%>"></td>

                <td>出处</td> <td><input type="text" width="100%" name="newsfrom"  value="<%=newRealese.getNewsFrom()  %>"></td>
		<td>是否置顶</td> <td><input type="text" width="100%" name="top"  value="<%=newRealese.getTop()  %>"></td>
		    </tr>
			<tr>
                <td>新闻发布时间</td> <td><input type="text" width="100%" name="newstime"  value="<%=newRealese.getNewsTime()  %> "></td>
                <td>新闻点击次数</td> <td><input type="text" width="100%" name="hits"  value="<%=newRealese.getHits()  %>"></td>
			</tr>
			<tr>
                <td>新闻状态</td> <td><input type="text" name="state" width="100%"  value="<%=newRealese.getState()  %>"></td>
                <td>新闻标记</td> <td><input type="text" width="100%" name="tag"  value="<%=newRealese.getTag()  %>"></td>                                                                      
		    </tr>
            <tr>
  </table>
	</td>
    <td width="5%">right</td>
  </tr>
  <tr>
    <td> </td>
    <td>
	<div align="center" style="width:80%">  
            <textarea id="newsEditor" name="content" style="height: 80%"><%=newRealese.getContent()  %></textarea>  
   <br/>  
   <input type="submit" value="发 布">  
        <script type="text/javascript">  
            UE.getEditor('newsEditor');  
          var content=UE.getPlainTxt();//s就是编辑器的带格式的内容
        </script>  
             </div>	
	</td>
    <td> </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

基于jsp的新闻发布系统
