Java【工具类】时间戳转化为正常格式的时间

JAVA代码转化时间戳

package com.test;


import java.util.Date;
import java.lang.annotation.Annotation;
import java.lang.reflect.*;
import java.text.SimpleDateFormat;

public class MainTest {
    public static final String TIME_FORMATER = "yyyy-MM-dd HH:mm:ss";
    public static void main(String[] args) throws ClassNotFoundException, NoSuchMethodException, InvocationTargetException, IllegalAccessException {
        Long dateStr=1574202291473l;
        testDateStr(dateStr);
    }
    public  static  void  testDateStr(Long dateStr){
        Date date=new  Date(dateStr);
        String  normalDate=new SimpleDateFormat(TIME_FORMATER).format(date);
        System.out.println("时间戳 : "+dateStr);
        System.out.println("normalDate : "+normalDate);
    }

    /******
     时间戳 : 1574202291473
     normalDate : 2019-11-20 06:24:51
