一、MySQL数据库相关配置
事先在数据库中录入了6条新闻信息
二、配置富文本编辑器UEditor
首先需要进行下载，下载地址：http://ueditor.baidu.com/website/download.html
下载完成后将压缩包解压并重命名
将解压出的文件复制到项目的web文件夹下
将ueditor文件夹下jsp/lib中的jar包复制到WEB-INF下的lib文件夹下，并添加项目依赖
在ueditor文件夹下的jsp/lib路径下的config.json文件夹内配置图片访问路径
路径前缀选用tomcat的输出路径
在嵌入编辑器的jsp页面内要先引入ueditor的js文件
下方的红框内的UE.getEditor是将对应区域（“Content”）的文本域转换成编辑器。
三、实现新闻的增删改查功能
在新闻展示页面，可以进行新闻的增删改查操作
新闻展示页面代码（ShowNews.jsp）：

在我们的项目中，新闻的增删改查功能主要由NewsService业务类具体实现
NewsService代码：
import java.sql.*;
import java.util.ArrayList;
import java.util.List;
public class NewsService {
//添加新闻
public boolean AddNews(News news) throws ClassNotFoundException, SQLException {
Statement statement;
Connection conn ;
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8","root","Guozhaojie610");
String sql="insert into new_schema.news (newsID,newsTitle,newsContent,newsAuthor) " +
"values ('"+news.getNewsId()+"','"+news.getNewsTitle()+"','"+news.getNewsContent()+"','"+news.getNewsAuthor()+"')";
statement=conn.createStatement();
int result =statement.executeUpdate(sql);
if (result>0)return true;
else return false;
}
//删除新闻
public boolean DeleteNews(int newsId) throws ClassNotFoundException, SQLException {
Statement statement = null;
Connection conn ;
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8","root","Guozhaojie610");
String sql= "delete from new_schema.news where newsID="+newsId;
statement=conn.createStatement();
int result = statement.executeUpdate(sql);
if(result>0)return true;
else return false;
}
//更新新闻
public boolean UpdateNews(News news) throws ClassNotFoundException, SQLException {
Statement statement = null;
Connection conn ;
ResultSet rs;
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8","root","Guozhaojie610");
String sql="update new_schema.news set newsTitle ='"+news.getNewsTitle()+"', newsContent ='"+news.getNewsContent()+"', newsAuthor ='"+news.getNewsAuthor()+"' where newsID="+news.getNewsId();
statement = conn.createStatement();
int result = statement.executeUpdate(sql);
if(result>0)return true;
else return false;
}
//查询新闻
public News QueryIndividualNews(int newsID)throws ClassNotFoundException, SQLException {
Statement statement = null;
Connection conn;
ResultSet rs;
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8", "root", "Guozhaojie610");
String sql = "Select * from new_schema.news where newsID=" + newsID;
statement = conn.createStatement();
rs = statement.executeQuery(sql);
News n = new News();
if (rs.next()) {
n.setNewsId(rs.getInt("newsID"));
n.setNewsTitle(rs.getString("newsTitle"));
n.setNewsAuthor(rs.getString("newsAuthor"));
n.setNewsContent(rs.getString("newsContent"));
}
return n;
}
//查询数据库内所有新闻
public List<News> QueryNews() throws ClassNotFoundException, SQLException {
Statement statement = null;
Connection conn ;
ResultSet rs;
Class.forName("com.mysql.cj.jdbc.Driver");
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306?serverTimezone=GMT&characterEncoding=utf-8","root","Guozhaojie610");
String sql = "Select * from new_schema.news";
statement=conn.createStatement();
rs = statement.executeQuery(sql);
List<News> NewsList = new ArrayList<News>();
while (rs.next()){
News n = new News();
n.setNewsId(rs.getInt("newsID"));
n.setNewsTitle(rs.getString("newsTitle"));
n.setNewsAuthor(rs.getString("newsAuthor"));
n.setNewsContent(rs.getString("newsContent"));
NewsList.add(n);
}
return NewsList;
}
}
（1）点击添加新闻，将跳转到添加新闻页面，借助富文本框完成新闻信息的输入

</div>
</form>
</body>
</html>
点击提交后，页面将填写的信息转发给AddNewsServlet，AddNewsServlet通过调用NewsService中的AddNews方法将信息录入数据库中，完成新闻的添加
AddNewsServlet代码：
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.sql.SQLException;
@WebServlet(urlPatterns = "/AddNewsServlet")
public class AddNewsServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
response.setContentType("text/html; charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setHeader("Context-Type","text/html;charset=utf-8");
News news =new News();
news.setNewsId(Integer.valueOf(request.getParameter("newsid")));
news.setNewsAuthor(request.getParameter("author"));
news.setNewsContent(request.getParameter("Content"));
news.setNewsTitle(request.getParameter("title"));
NewsService newsService=new NewsService();
try {
newsService.AddNews(news);
request.getRequestDispatcher("ShowNewsServlet").forward(request,response);
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
}
（2）在新闻展示页面点击某一新闻的删除选项，将启用DeleteNewsServlet，DeleteNewsServlet通过调用NewsService中的DeleteNews方法删除数据库中相应新闻ID的信息

} catch (SQLException e) {
e.printStackTrace();
}
request.getRequestDispatcher("ShowNewsServlet").forward(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

}
}
（3）在新闻展示页面点击某一新闻的修改选项，将跳转到新闻编辑页面（与新闻添加页面相似），借助富文本框完成新闻信息的修改

点击提交后，页面将填写的信息转发给UpdateNewsServlet，UpdateNewsServlet通过调用NewsService中的UpdateNews方法修改数据库中相应新闻的信息，完成新闻的修改
UpdateNewsServlet代码：
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

} catch (SQLException e) {
e.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}
}
（4）在新闻展示页面点击某一新闻的查看选项，将启用QueryNewsServlet，QueryNewsServlet通过调用NewsService中的QueryIndividualNews方法获取对应的新闻实例，并转发给NewsDetail页面，展示相应新闻的所有内容。
QueryNewsServlet代码：
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException{
int newsID=Integer.valueOf(request.getParameter("newsid"));
NewsService newsService=new NewsService();
try {
News news=newsService.QueryIndividualNews(newsID);
request.setAttribute("news",news);
request.getRequestDispatcher("NewsDetail.jsp").forward(request,response);
}catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
（5）HostNewsServlet负责在新闻总览页面提供每条新闻的索引，点击即可查看其详情
HostNewsServlet代码：
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;
@WebServlet(urlPatterns = "/HostNewsServlet")
public class HostNewsServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
NewsService newsService=new NewsService();
try {
List<News> lstNews=newsService.QueryNews();
for (News s:lstNews
) {
System.out.println(s.getNewsTitle());
}
request.setAttribute("lstNews",lstNews);
request.getRequestDispatcher("Hostpage_News.jsp").forward(request,response);
