新闻web小酌

首页如上

类图如下：

添加新闻的方法（dao）：

 public boolean Add(News news) {
         boolean flag=false;
                 Connection con =getConnectionData();
                 QueryRunner queryRunner = new QueryRunner();
                 String sql="INSERT INTO newscon(newstype,title,author,abstrac ,content,picture) VALUE(?,?,?,?,?,?)";
                 Object[] paras={news.getNewstype(),news.getTitle(),news.getAuthor(),news.getAbstrac(),news.getContent(),news.getUrl()};
                 int count=0;
                 try {
                      count= queryRunner.update(con,sql,paras);
                 } catch (SQLException e) {
                     throw new RuntimeException(e.getMessage(),e);
                 }
                  closeAll();
                  if(count>0){
                     flag=true;
                  }
                 return flag;
     } 

servlet方法：

 public class AddNews extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         doPost(request,response);
     }

     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         request.setCharacterEncoding("utf-8");
         if(request.getMethod().equals("GET")){
             request.getRequestDispatcher("/newspages/news_add.jsp").forward(request,
                     response);
         }else {
             String path = request.getContextPath();
             String basePath = request.getScheme() + "://" + request.getServerName()
                     + ":" + request.getServerPort() + path + "/";
             response.setContentType("text/html;charset=UTF-8");
             request.setCharacterEncoding("UTF-8");
             HttpSession session = request.getSession();
             boolean flag=false;
             try {
                 List<News> list = (List<News>) FormUtil.assembleObjectList(request,News.class);
                 News news = list.get(0);
                 NewsDaoimpl dao=new NewsDaoimpl();
                 flag = dao.Add(news);

             } catch (NoSuchFieldException e) {
                 e.printStackTrace();
             } catch (Exception e) {
                 e.printStackTrace();
             }
             if (flag) {
                 response.sendRedirect(path);

             }else {
                 request.getRequestDispatcher("/index.jsp").forward(request,
                         response);
             }

         }
     }

 }

插入标题：

 public class AddTitleServlet extends HttpServlet {
     public void doGet(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         doPost(request, response);
     }

     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
         request.setCharacterEncoding("utf-8");
         if (request.getMethod().equals("GET")) {
             request.getRequestDispatcher("/newspages/news_add.jsp").forward(
                     request, response);
         } else {
             String path = request.getContextPath();
             String basePath = request.getScheme() + "://"
                     + request.getServerName() + ":" + request.getServerPort()
                     + path + "/";
             response.setContentType("text/html;charset=UTF-8");
             request.setCharacterEncoding("UTF-8");
             HttpSession session = request.getSession();
             boolean flag = false;
             try {
                 List<Topic> list = (List<Topic>) FormUtil.assembleObjectList(
                         request, Topic.class);
                 Topic topic = list.get(0);
                 NewsDaoimpl dao = new NewsDaoimpl();
                 flag = dao.AddTitle(topic);

             } catch (NoSuchFieldException e) {
                 e.printStackTrace();
             } catch (Exception e) {
                 e.printStackTrace();
             }
             if (flag) {
                 response.sendRedirect(path);

             } else {
                 request.getRequestDispatcher("/index.jsp").forward(request,
                         response);
             }
         }
     }

 }

标题的动态加载：

index：

 <c:forEach var="item" items="${requestScope.Toplist}">
              <a style="color:blue;font-size:16px;" href='${pageContext.request.contextPath }/DoIndexServlet?id=${item.nid}'>
                 ${item.newstype}
              </a>
          </c:forEach>
         </li>
       </ul>
       <ul class="classlist">
         <c:forEach var="item" items="${requestScope.newsList }">
            <li><a href='newspages/news_read.jsp'>${item.title }</a>
            <span>
                    <c:forEach var="item1" items="${TimeList}">
                        ${item1.beginDatetime}
                    </c:forEach>
            </span>
            </li>
         </c:forEach>

impl：

 public List<Topic> AllTitle() {

         Connection con=getConnectionData();
         String sql="select nid,newstype from type";
         QueryRunner query=new QueryRunner();
         List<Topic> list=null;
         try {

             list= query.query(con, sql,new BeanListHandler<Topic>(Topic.class));
         } catch (SQLException e) {
             new RuntimeException(e.getMessage());

         }
         return list;
     }
