操作方法
打开eclipse软件，建立web应用，在webContext建立jsp文件
%@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" %>
<!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>
<p>当前系统时间：</p><% Date date=new Date(); SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");%> <p><%=sdf.format(date)%></p></body></html>
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;
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); }}
