Chapter 11. Business calendar - JBoss JBPM 3.0.4 userguide 英文版文档
This chapter describes the business calendar of jBPM. The business calendar knows about business hours and is used in calculation of due dates for tasks and timers.
The business calendar is able to calculate a date by adding a duration and a date.
A duration is specified in absolute or in business hours. Let's look at the syntax:
<quantity> [business] <unit>
Where <quantity> is a piece of text that is parsable with Double.parseDouble(quantity). <unit> is one of {second, seconds, minute, minutes, hour, hours, day, days, week, weeks, month, months, year, years}. And adding the optional indication business means that only business hours should be taken into account for this duration. Without the indication business, the duration will be interpreted as an absolute time period.
The file org/jbpm/calendar/jbpm.business.calendar.properties specifies what business hours are. The configuration file can be customized and a modified copy can be placed in the root of the classpath.
This is the example business hour specification that is shipped by default in jbpm.business.calendar.properties:
hour.format=HH:mm #weekday ::= [<daypart> [& <daypart>]*] #daypart ::= <start-hour>-<to-hour> #start-hour and to-hour must be in the hour.format #dayparts have to be ordered weekday.monday= 9:00-12:00 & 12:30-17:00 weekday.thuesday= 9:00-12:00 & 12:30-17:00 weekday.wednesday= 9:00-12:00 & 12:30-17:00 weekday.thursday= 9:00-12:00 & 12:30-17:00 weekday.friday= 9:00-12:00 & 12:30-17:00 weekday.saturday= weekday.sunday= day.format=dd/MM/yyyy # holiday syntax: <holiday> # holiday period syntax: <start-day>-<end-day> # below are the belgian official holidays holiday.1= 01/01/2005 # nieuwjaar holiday.2= 27/3/2005 # pasen holiday.3= 28/3/2005 # paasmaandag holiday.4= 1/5/2005 # feest van de arbeid holiday.5= 5/5/2005 # hemelvaart holiday.6= 15/5/2005 # pinksteren holiday.7= 16/5/2005 # pinkstermaandag holiday.8= 21/7/2005 # my birthday holiday.9= 15/8/2005 # moederkesdag holiday.10= 1/11/2005 # allerheiligen holiday.11= 11/11/2005 # wapenstilstand holiday.12= 25/12/2005 # kerstmis business.day.expressed.in.hours= 8 business.week.expressed.in.hours= 40 business.month.expressed.in.business.days= 21 business.year.expressed.in.business.days= 220
