1、打开eclipse软件，建立web应用，在webContext建立jsp文件
2、%@page import="java.text.SimpleDateFormat"%
jsp导入包的格式<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
设置编码格式为utf-8<%@page import="java.util.Date" %>
3、<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html>
<head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body>
4、当前系统时间：<% Date date=new Date(); SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");%> <%=sdf.format(date)%></body></html>
5、在写一个servlet显示当前时间比较一下那个简单
import java.io.IOException;import java.io.PrintWriter;import java.text.SimpleDateFormat;import java.util.Date;
import javax.servlet.ServletException;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;
6、public class DateSrevlet extends HttpServlet{ @Override protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { request.setCharacterEncoding("utf-8"); response.setContentType("text/html;charset=utf-8"); Date date=new Date(); SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss"); PrintWriter out=response.getWriter(); String str=sdf.format(date); out.println("当前时间："+str); }}
