一下是所有源码：

在中国时间为用东八区，所以TimeZone.getTimeZone("GMT+08:00");中的GMT+08:00来表示北京时间，默认的参数为UTC，运行后会比北京时间晚8小时。

import java.util.Calendar;
import java.util.TimeZone;

public class DateTime {
TimeZone tz = TimeZone.getTimeZone("GMT+08:00");

Calendar ca = Calendar.getInstance(tz);

public String getDate() {

  String strMonth = String.valueOf(ca.get(Calendar.MONTH) + 1);// 获取当前月时间并转为字符串型
  String strDate = String.valueOf(ca.get(Calendar.DATE));// 获取当前日时间并转为字符串型
  String SysDate = null;
  String strMinute = String.valueOf(ca.get(Calendar.MINUTE));
  String strHour = String.valueOf(ca.get(Calendar.HOUR_OF_DAY));
  String SysTime = null;
  String SysDateTime = null;

// ca.get(Calendar.MONTH)+1为什么加一是因为,0表示1月,1表示2月,依次类推

  if ((ca.get(Calendar.MONTH) + 1) <= 9 && ca.get(Calendar.DATE) <= 9) {
   SysDate = "0" + strMonth + "0" + strDate;
  } else if ((ca.get(Calendar.MONTH) + 1) > 9
    && ca.get(Calendar.DATE) > 9) {
   SysDate = strMonth + strDate;
  } else if ((ca.get(Calendar.MONTH) + 1) <= 9
    && ca.get(Calendar.DATE) > 9) {
   SysDate = "0" + strMonth + strDate;
  } else if ((ca.get(Calendar.MONTH) + 1) > 9
    && ca.get(Calendar.DATE) <= 9) {
   SysDate = strMonth + "0" + strDate;
  }

if (ca.get(Calendar.HOUR_OF_DAY) <= 9 && ca.get(Calendar.MINUTE) <= 9) {
SysTime = "0" + strHour + "0" + strMinute;

} else if (ca.get(Calendar.HOUR_OF_DAY) > 9
&& ca.get(Calendar.MINUTE) > 9) {

SysTime = strHour + strMinute;

} else if (ca.get(Calendar.HOUR_OF_DAY) <= 9
&& ca.get(Calendar.MINUTE) > 9) {

SysTime = "0" + strHour + strMinute;

} else if (ca.get(Calendar.HOUR_OF_DAY) > 9
&& ca.get(Calendar.MINUTE) <= 9) {

SysTime = strHour + "0" + strMinute;

}
SysDateTime = SysDate + SysTime;

return SysDateTime;

}
