為什么登錄失敗？代碼和登錄帳號密碼都沒問題啊
<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8" %>
<%
request.setCharacterEncoding("utf-8");
?%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String username="";
String password="";
request.setCharacterEncoding("utf-8");
//如果用戶和密碼都是admin，則登陸成功
if("admin".equals(username)&&"admin".equals(password))
{
request.getRequestDispatcher("login_success.jsp").forward(request,response);
}
else
{
response.sendRedirect("login_failure.jsp");
}
%>

你都沒有獲取傳過來的用戶名和密碼，那當(dāng)然是登陸失敗了
username = request.getAttribute("username");
password =?request.getAttribute("password");
