很棒的新聞發(fā)布系統(tǒng)分享給大家，希望大家喜歡。
下面就讓我們來(lái)說(shuō)一說(shuō)基于jsp的新聞發(fā)布系統(tǒng)，其中使用的技術(shù)有JavaBean、fillter、數(shù)據(jù)庫(kù)等，能夠?qū)崿F(xiàn)新聞的發(fā)布功能，在發(fā)布之后能夠進(jìn)行對(duì)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(jìn)行查詢功能，其中引用了百度編輯器，能夠進(jìn)行圖文并茂的編輯，極大地方便用戶的使用。
注：完整項(xiàng)目下載地址：新聞發(fā)布系統(tǒng)
一、效果演示
首先讓我們來(lái)看一看實(shí)現(xiàn)的效果：
下面是登陸的首界面：
圖1 首界面
管理員登錄頁(yè)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(jìn)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(jìn)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(duì)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(hào)進(jìn)行查詢所需的信息，然后在新的頁(yè)面上進(jìn)行顯示。
二、具體實(shí)現(xiàn)過(guò)程
1、環(huán)境：編程環(huán)境為NetBeans8.0和Oracle數(shù)據(jù)庫(kù)
2、數(shù)據(jù)庫(kù)后臺(tái)的設(shè)計(jì)
在新聞管理系統(tǒng)中，我們需要數(shù)據(jù)庫(kù)后臺(tái)管理，其具體步驟如下所示：
根據(jù)所需的業(yè)務(wù)進(jìn)行建表，可參見(jiàn)如下所示：建立數(shù)據(jù)庫(kù)
3、編寫(xiě)步驟：
（1）首先建立以個(gè)項(xiàng)目，在此命名為Demo_08_NewsRealese,項(xiàng)目布局結(jié)構(gòu)如下圖所示，根據(jù)如下布局對(duì)項(xiàng)目進(jìn)行布局設(shè)計(jì)，方便后面的編程，項(xiàng)目中web-inf為項(xiàng)目配置文件夾，images文件夾用于儲(chǔ)存項(xiàng)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(xiàng)目布局結(jié)構(gòu)圖
接著，我們進(jìn)行創(chuàng)建數(shù)據(jù)庫(kù)連接層，即DAO和VO，分別存于包c(diǎn)om.lut.beans和dao,類命名分別命名為NewsRealese、NewsRealeseDao，對(duì)于類NewsRealese而言，主要是實(shí)現(xiàn)字符串的包裝，其內(nèi)容與數(shù)據(jù)庫(kù)里邊的內(nèi)容一一對(duì)應(yīng)，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(duì)于DAO類，主要用于實(shí)現(xiàn)數(shù)據(jù)庫(kù)的連接問(wèn)題，進(jìn)行數(shù)據(jù)庫(kù)的鏈接，在連接過(guò)程中需要用到各種有關(guān)數(shù)據(jù)庫(kù)的技術(shù)，在這里我們使用的是Oracle數(shù)據(jù)庫(kù)，其獲取鏈接的方式為如下代碼，其中第一行為驅(qū)動(dòng)程序名，第二行為數(shù)據(jù)庫(kù)地址（orcl為Oracle數(shù)據(jù)庫(kù)中的SID，在安裝Oracle數(shù)據(jù)庫(kù)時(shí)需要記住），第三行為具體的連接，及使用URL找到數(shù)據(jù)庫(kù)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");

（4）管理員登錄界面，命名為adminLogin.jsp頁(yè)面，使用連接數(shù)據(jù)庫(kù)的方式進(jìn)行登錄，在這里我們的管理員名稱為Scott，密碼為wjk139，管理員登錄界面的實(shí)現(xiàn)代碼如下所示

在登錄的過(guò)程中，我們需要進(jìn)行判斷，命名為checkLogin.java,，通過(guò)此類進(jìn)行判斷登錄是否成功，若成功，則跳轉(zhuǎn)到管理界面，若失敗，則停留在當(dāng)前界面，其代碼如下所示：

（5）管理員登陸之后的界面，命名為adminManager.jsp頁(yè)面，在管理員界面能夠進(jìn)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(yè)面，命名為a_addNews.jsp，能夠進(jìn)行新聞的增加，在添加完信息之后，我們點(diǎn)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(shí)需要對(duì)新聞進(jìn)行編輯，對(duì)于長(zhǎng)篇幅新聞內(nèi)容且含有圖片的新聞內(nèi)容的編寫(xiě)，在這兒我們使用功能強(qiáng)大的百度編輯器，首先從官網(wǎng)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(jié)構(gòu)
圖10 百度富文本編輯器文件夾結(jié)構(gòu)圖
然后只需將整個(gè)文件夾拷貝到項(xiàng)目下即可，在使用時(shí)引入和修改路徑，在jsp頁(yè)面里邊我已經(jīng)配置好引用，只需修改路徑即可，修改路徑時(shí)只需將editor_config.js中查找URL變量配置編輯器在你項(xiàng)目中的路徑。其中./ueditor為項(xiàng)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(yè)面，在添加完新聞之后，只需點(diǎn)擊發(fā)布即可進(jìn)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" %>

在增加新聞時(shí)，需要對(duì)Servlet進(jìn)行配置，如下圖所示所示為配置文件的結(jié)構(gòu)：
插入數(shù)據(jù)Servlet結(jié)構(gòu)圖
下面是InserOneNews.java代碼，能夠進(jìn)行對(duì)數(shù)據(jù)的插入功能
