JSP显示当前系统时间的四种方式:

第一种java内置时间类实例化对象:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
  <base href="<%=basePath%>" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
  
  <title>My JSP 'time4.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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
	-->
 
 </head>
 
 <body>
  <%
  java.text.SimpleDateFormat simpleDateFormat = new java.text.SimpleDateFormat( 
   "yyyy-MM-dd HH:mm:ss"); 
  java.util.Date currentTime = new java.util.Date(); 
  String time = simpleDateFormat.format(currentTime).toString();
  out.println("当前时间为:"+time);
   %>
   
 </body>
</html>

第二种方式使用JSP内置USEBEAN实例化时间类:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
  <base href="<%=basePath%>" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
  
  <title>显示系统时间方法一:</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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
	-->
 
 </head>
 
 <body>
  <jsp:useBean id="time" class="java.util.Date"/>
  	现在时间:<%=time%>
 </body>
</html>

第三种方式使用JSP USEBEAN type与beanName配对使用:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
  <base href="<%=basePath%>" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
  
  <title>My JSP 'time2-useBean-type-beanName.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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
	-->
 
 </head>
 
 <body>
   <jsp:useBean id="time" type="java.io.Serializable" beanName="java.util.Date"/>
  	现在时间:<%=time%>
 </body>
</html>

第四种方式使用JSP setproperty设置属性:

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
 <head>
  <base href="<%=basePath%>" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
  
  <title>My JSP 'time3-setproperty.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">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >
	-->
 
 </head>
 
 <body>
  jsp:setproperty 实例<hr>
  <jsp:useBean id="time" class="java.util.Date">
  	<jsp:setProperty name="time" property="hours" param="hh"/>
  	<jsp:setProperty name="time" property="minutes" param="mm"/>
  	<jsp:setProperty name="time" property="seconds" param="ss"/>
  </jsp:useBean>
  <br>
  设置属性后的时间:${time} }
  <br>
  
 </body>
</html>
