JavaBean在JSP中显示时间

创建DateTimeBean的类，将其放置于org.caiduping.bean的包中，实现时间，星期的封装。

package org.caiduping.bean;
 
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
 
public class DateTimeBean {
    private String dateTime;
    private String week;
    //Calendar对象
    private Calendar calendar=Calendar.getInstance();
    /*
     * 获取日期和时间
     * 
     * */
    public String getdateTime(){
        //获取当前时间
        Date currDate=Calendar.getInstance().getTime();
        //实例化SimpleDateFormat
        SimpleDateFormat sdf=new SimpleDateFormat("yyyy年MM月dd日 HH点mm分ss秒");
        //格式化日期时间
        dateTime=sdf.format(currDate);
        return dateTime;
    }
    /*
     * 获取星期几
     * 
     * */
    public String getweek(){
        //定义数组
        String[] weeks={"星期日","星期一","星期二","星期三","星期四","星期五","星期六"};
        //获取一星期的某天
        int index=calendar.get(Calendar.DAY_OF_WEEK);
        //获取星期几
        week=weeks[index-1];
        return week;
         
    }
}

而index.jsp则实例化DateTimeBean对象：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

  <head>
    <base href="<%=basePath%>">
     
    <title>电子时钟</title>
    <style type="text/css">
      #clock{
      500px;
      height:100px;
      padding-top: 20px;
      border:solid 5px black;
      }  
    #week{
    padding-top: 20px;
     
    }
    </style>

  </head>
   
  <body>
    <jsp:useBean id="date" class="org.caiduping.bean.DateTimeBean"></jsp:useBean>
    <div id="clock">
    <div id="time">
    <jsp:getProperty property="dateTime" name="date"/>
    </div>
   <div id="week">
    <jsp:getProperty property="week" name="date"/>
    </div>
    </div>
  </body>
</html>
