求一套完整的JAVA WEB項(xiàng)目的網(wǎng)絡(luò)購物網(wǎng)站源代碼

雖然源碼便宜到十塊錢能買一套或者n套了吧，不過10分就想買還是有點(diǎn)too young too sample

java web網(wǎng)頁登錄功能原理(最好有代碼?

想要實(shí)現(xiàn)一個(gè)簡(jiǎn)單的登錄功能的話，可以使用Servlet+jsp來實(shí)現(xiàn)，jsp編寫登錄界面和登錄后的要出現(xiàn)信息界面和登錄失敗的信息界面，Servlet類用來對(duì)表單提交的用戶名和密碼進(jìn)行判斷和處理。

具體代碼如下：

Servlet類：

public class DemoServlet extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

String loginname = request.getParameter("loginname");

String password = request.getParameter("password");

if(loginname.equals("a") password.equals("a")){

request.setAttribute("msg", "登錄成功");

request.getRequestDispatcher("/loginsuccess.jsp").forward(request, response);

}else{

request.setAttribute("msg", "登錄失敗");

request.getRequestDispatcher("/loginsuccess.jsp").forward(request, response);

}

}

public void doPost(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

doGet(request, response);

}

}

jsp頁面：

%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%

!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

html

head

titleDemo/title

meta http-equiv="pragma" content="no-cache"

meta http-equiv="cache-control" content="no-cache"

meta http-equiv="expires" content="0"

meta http-equiv="keywords" content="keyword1,keyword2,keyword3"

meta http-equiv="description" content="This is my page"

/head

body

form action="demoServlet" method="post"

input type="text" name="loginname"/br/

input type="password" name="password"/br/

input type="submit" value="登錄"/

/form

/body

/html

登錄信息頁面：

%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%

%@ taglib prefix="c" uri="標(biāo)簽庫地址"%

!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

html

head

titleMy JSP 'loginsuccess.jsp' starting page/title

meta http-equiv="pragma" content="no-cache"

meta http-equiv="cache-control" content="no-cache"

meta http-equiv="expires" content="0"

meta http-equiv="keywords" content="keyword1,keyword2,keyword3"

meta http-equiv="description" content="This is my page"

/head

body

${msg }

/body

/html

需要介紹一下：登錄信息的這個(gè)頁面中的${msg }是使用jstl標(biāo)簽，需要在jsp頁面中導(dǎo)入jstl標(biāo)簽庫，使用這個(gè)標(biāo)簽庫可以節(jié)省很多代碼量。
