JSP中的几个实用函数（时间判断/IP获取/累计次数/视频播放等）

<%@ page import="java.util.Calendar"%>
<%! private int count=0;
    public int getCount()
   {
      return ++count;
   }
%><b>&nbsp;
<% Calendar calendar=Calendar.getInstance();
   int hourOfDay=calendar.get(Calendar.HOUR_OF_DAY);
   if(hourOfDay<=12){
%>Good morning!
<%}else if(hourOfDay<=18){
%>Good afternoon!
<%}else {
%>Good evening!
<%}%>
This is the <font color=red size=+1><%=getCount()%></font> time this page has been visited!</b>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Your IP:<%=request.getRemoteAddr()%>


播放视频的！
