1, Problem Description:

I get the maximum time of the day:

 Public Static Date Getendofday (date date) {        = localdatetime.ofinstant (Instant.ofepochmilli (Date.gettime ()), Zoneid.systemdefault ());;         = Localdatetime.with (Localtime.max);         return Date.from (Endofday.atzone (Zoneid.systemdefault ()). Toinstant ());    

Gets the maximum time to insert into the database, always one second, for example, the current time is 2018-04-26 22:00:01 the maximum time obtained is: 2018-04-26 23:59:59 Here you can see the source code for hours:

To set Max's source code:

Static  {        for (int i = 0; i < hours.length; i++) {            new localtime (i, 0, 0, 0);        }         = Hours[0];         = Hours[12];         = Hours[0];         New LocalTime (,999_999_999);    }

After inserting into the database became 2018-04-27 00:00:00, it was strange to add a second, after checking the data found that:MySQL database for milliseconds greater than 500 of data will be carry!!!

2. Solutions

I changed the last millisecond to 0, and by looking at the source code of the Java time class, I found that it was set time,

 /*** Obtains an instance of {@codelocaltime} from an hour, minute, second and nanosecond. * <p> * This returns a {@codeLocalTime} with the specified hour, minute, second and nanosecond. *     * @paramHour The Hour-of-day to represent, from 0 to *@paramminute the Minute-of-hour to represent, from 0 to *@paramsecond The Second-of-minute to represent, from 0 to *@paramNanoofsecond The Nano-of-second to represent, from 0 to 999,999,999 *@returnThe local time, NOT NULL *@throwsdatetimeexception If the value of any field was out of range*/     Public StaticLocalTime of (intHourintMinuteintSecondintNanoofsecond)        {Hour_of_day.checkvalidvalue (HOUR);        Minute_of_hour.checkvalidvalue (MINUTE);        Second_of_minute.checkvalidvalue (SECOND);        Nano_of_second.checkvalidvalue (Nanoofsecond); returnCreate (hour, minute, second, nanoofsecond); }

So I modified the code to get the maximum time of the day:

 /**   * get the maximum time of the day 23:59:59 * New LocalTime (23,     59, 59, 999_999_999) * is not set to the maximum value since MySQL (some versions) will have a carry operation with a millisecond value greater than 500 for the inserted time after setting the maximum value, so the millisecond value is set to 0. *   @param   date *   @return  */ public  static   date getendofday (date date) {LocalDateTime Localdat ETime  = Localdatetime.ofinstant (Instant.ofepochmilli (Date.gettime ()),        Zoneid.systemdefault ());;        LocalDateTime endofday  = Localdatetime.with (Localtime.of (23,59,59,0 return   Date.from (Endofday.atzone (    Zoneid.systemdefault ()). Toinstant ()); }

Check it out, OK.
