基于jsp的新闻发布系统

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了基于jsp的新闻发布系统相关的知识，希望对你有一定的参考价值。
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，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（下面的部分代码和下载地址的有所区别，但是只是优化而已，出问题可随时问我）
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;

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;

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
