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>
