2021-12-16T14:05:09.202+08:00 带时区的时间类型转换

（1）带时区的时间类型 2021-12-16T14:05:09.202+08:00 转换成常用的年月日时分秒  2021-12-16 14:05:09

  String oldDateStr = "2021-12-16T14:05:09.202+08:00";
        try{
            if(!oldDateStr.contains(".")){
                oldDateStr = oldDateStr.replace("+",".00+");
            }   //防止不带毫秒的时间数据导致转换异常
            DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSXXX");
            Date date = df.parse(oldDateStr);
            DateFormat df2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            String newDateStr = df2.format(date);
            System.out.println(newDateStr);
        }catch(Exception e){
            throw new RuntimeException(e);
        }
