新闻发布会

项目所需要的一些实现类 servlet 工具类

1.实现登录功能

前端界面的代码

1 <form action="<%=path %>/LonginServlet" method="post">
2       <label> 登录名 </label>
3       <input type="text" name="uname" value='<%=request.getParameter("uname")==null?"":request.getParameter("uname") %>' class="login_input" />
4       <label> 密&#160;&#160;码 </label>
5       <input type="password" name="upwd" value='<%=request.getParameter("upwd")==null?"":request.getParameter("upwd") %>' class="login_input" />
6       <input type="submit" class="login_sub" value="登录" />
7       <label id="error"> </label>
8       <img src="images/friend_logo.gif" alt="Google" id="friend_logo" />
9     </form>

登录实现类代码

 1 public boolean loginGetBool(Admin admin) {
 2       rs=  executeSelect("select *from admin where name=? and \"pwd\"=?",admin.getAname(),admin.getApwd());
 3       try {
 4         if(rs.next()){
 5               return true;
 6           }
 7       } catch (SQLException e) {
 8         // TODO Auto-generated catch block
 9         e.printStackTrace();
10       }
11       return false;
12     }

登录servlet

public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        //接收请求时的编码utf-8
          request.setCharacterEncoding("utf-8");
          response.setContentType("text/html;charset=utf-8");
          String  name=request.getParameter("uname");
          String  pwd=request.getParameter("upwd");
    
                Admin admin=new Admin(name,pwd);
                System.out.println(admin.getAname());
               
               AdminDaoImpl adi=new AdminDaoImpl();

                String dbn=adi.login(admin);
             
                if(dbn!=null){
                     
                    Cookie cookie=new Cookie("unameCookie",name);
                    cookie.setMaxAge(60*60*24);
                    
                    response.addCookie(cookie);
                
                    System.out.println("登陆成功!");
                    HttpSession session= request.getSession();
                    session.setAttribute("uname", name);
                    session.setMaxInactiveInterval(60*10);
                    
                    response.sendRedirect(request.getContextPath()+"/newspages/admin.jsp");
                }else{
                    response.sendRedirect(request.getContextPath()+"/index.jsp");
                }
    }

2.实现新增新闻

JSP丶新闻发布会系统

新增实现类方法

 1 public boolean addNews(News news) {
 2         Date date=new Date();
 3         DateFormat format=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
 4         Date time = null;
 5         try {
 6             time = format.parse(format.format(date));
 7         } catch (ParseException e) {
 8             // TODO Auto-generated catch block
 9             e.printStackTrace();
10         }
11         
12             Object[] obj={news.getNauthor(),news.getNcontent(),time,null,news.getNtitle(),news.getNtypeid()};
13     
14         
15       
16       return  executeUpdate("INSERT INTO newsrecord (`nauthor`,`ncontent`,`startTime`,`endUpdateTime`,`ntitle`,`ntypeid`) values(?,?,?,?,?,?)",obj);
17         
18       
19     }
