带时区的日期转换成long类型的timestamp

package wyh;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class DateTest {

	public static void main(String[] args) {
		String time = "2019-05-25T10:23:43.254Z";
		time = time.replace("Z", " UTC");//!!!特别注意，这里的UTC前面有个空格
		SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS Z");
		Date date = null;
		Long timestamp = 0L;
		try {
			date = format.parse(time);
			timestamp = date.getTime();
			System.out.println(timestamp);
		}catch(ParseException e) {
			e.printStackTrace();
		}

	}

}
