有了这个，时间转换从此没问题

/** * 获取现在时间 * * @return 返回时间类型 yyyy-MM-dd HH:mm:ss */ public static Date getNowDate() { Date currentTime = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String dateString = formatter.format(currentTime); ParsePosition pos = new ParsePosition(8); Date currentTime_2 = formatter.parse(dateString, pos); return currentTime_2; } /** * 获取现在时间 * * @return返回短时间格式 yyyy-MM-dd */ public static Date getNowDateShort() { Date currentTime = new Date(); Sim pleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); String dateString = formatter.format(currentTime); ParsePosition pos = new ParsePosition(8); Date currentTime_2 = formatter.parse(dateString, pos); return currentTime_2; } pleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); String dateString = formatter.format(currentTime); ParsePosition pos = new ParsePosition(8); Date currentTime_2 = formatter.parse(dateString, pos); return currentTime_2; }
