Try this (file.jsp):
试试这个（file.jsp）：
<%@ page import = "java.util.Date" %>
<%@ page import = "java.text.SimpleDateFormat" %>
<html>
<head>
<%
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String date = sdf.format(new Date());
%>
</head>
<body>
<p>Hello! The time is now <%=date%></p>
</body>
</html>
You can change the date format that suits you in "yyyy-MM-dd HH:mm:ss". And, <%=date%>displays the result. Good luck mate :)
您可以更改适合您的日期格式"yyyy-MM-dd HH:mm:ss"。并且，<%=date%>显示结果。祝你好运：）
