格式化显示时间
制作ASP程序时用DWMX2004系统自带的时间格式化工具就可以方便地实现目标显示格式,可惜PHP模组里没有类似的功能,
不过我们手写几个字符就搞定了
将 $row_rsLesson['N_Date']) 改为你的时间记录字段内容
输出的格式是: 年-月-日 你可以根据要求设定,例如:"m-d" 或者 "mdHi"等
这里用到两个函式 一个 是date() 一个 是strtotime()
date() :传入时间戳值，将时间戳格式化传回
strtotime () 将任何英文文本的日期时间描述解析为 UNIX 时间戳

Introduction to methods and usage of using Date and SimpleDateFormat classes to process time in Java
Apr 21, 2023 pm 03:01 PM
1. Introduction The Date class in the java.util package represents a specific time, accurate to milliseconds. If we want to use our Date class, then we must introduce our Date class. Writing the year directly into the Date class will not produce the correct result. Because Date in Java is calculated from 1900, so as long as you fill in the first parameter with the number of years since 1900, you will get the year you want. The month needs to be subtracted by 1, and the day can be inserted directly. This method is rarely used, and the second method is commonly used. This method is to convert a string that conforms to a specific format, such as yyyy-MM-dd, into Date type data. First, define an object of Date type Date

May 22, 2023 pm 04:52 PM
Stringbuild class Since the object content of the String class cannot be changed, a new String object will be constructed every time it is spliced, which is time-consuming and wastes memory space. At this time, you need to solve this problem through the StringBuild class provided by Java. StringBuilder is also called a variable character sequence. , it is a string buffer similar to String, which can be regarded as a container. Many strings can be held in the container. Variable means that the content in the StringBuilder object is variable. The construction method publicStringBuilder(): creates an empty buffer publicStringBuilder(Stringsr

How to solve the problem of springboot configuring date field to return timestamp
May 20, 2023 am 11:16 AM
I encountered a problem. After springboot was upgraded to 2.0, the date found from the database was received using Date and finally returned directly to the front end. It can be displayed normally in the yyyy-MM-ddHH:mm:ss format in Google Chrome. However, the date displayed in the IE browser is "garbled" because the springboot1.x version returns a timestamp in the Date field by default, and Google and IE will automatically convert the timestamp into yyyy-MM-ddHH:mm:ss ;After springboot2.0, spring will automatically convert the Date field into a UTC string (without configuration), so date needs to be converted into a timestamp or y
