session

1,session保存在操作方便，保存在服务器，同样需要setCharacterSet（“UTF—8”）

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>

<%@ page import="kooing.People" %>
<% 
    request.setCharacterEncoding("UTF-8");
    response.setCharacterEncoding("UTF-8");
    People people[]={new People("huanggabin","b",22)
                    ,new People("黄嘎兵","huanggabin",22)
                    ,new People("dsf","famale",22)};
    String message="";
    if(request.getMethod().equals("POST")){
        for(People personA:people){
            if(personA.getName().equals(request.getParameter("name"))&&
                    personA.getPassword().equals(request.getParameter("password"))){
                session.setAttribute("person",personA);
                response.sendRedirect(request.getContextPath()+"/welcom.jsp");
                return;
            }
        }
    }
%>
