【大数据开发】Java基础——UTC时间格式（2020-10-31T08:04:34+08:00）格式化方法

方法一（推荐）

package Test4

import java.text.SimpleDateFormat
import java.util.Date

import org.joda.time.DateTime

object Test4{
     

    def main(args: Array[String]): Unit = {
     

        val time = "2020-10-31T08:04:34+08:00"

        val sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")

        // org.joda.time.DateTime类
        val date = new DateTime(time).toDate

        val dt = sdf.format(date)

        val tempTime: Long = sdf.parse(dt).getTime

        println(tempTime)

        println(sdf.format(new Date(tempTime)))

    }
}

方法二

import java.text.SimpleDateFormat;
import java.util.Date;
 
public class Test {
     
 
	public static void main(String[] args) {
     
		SimpleDateFormat sdf1 = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
		SimpleDateFormat sdf2 = new SimpleDateFormat("yyyy/MM/dd");
		try {
     
		      Date date = sdf1.parse("2018-01-22T09:12:43.083Z");//拿到Date对象
		      String str = sdf2.format(date);//输出格式：2017-01-22 09:28:33
		      System.out.println(str);
		  } catch (Exception e) {
     
		      e.printStackTrace();
		  }
	}
 
}
