第14章 业务日历

本章描述jBPM的业务日历，业务日历是关于业务时间的，并且被用于为任务和定时器计算预期的时间。

业务日历能够通过对一个期限和日期进行增加来计算日期。

14.1 期限

期限用一个绝对的或业务时间来指定，让我们看看语法：

<quantity>[business]<unit>

<quantity>是一个文本块，它是可以使用Double.parseDouble(quantity)所解析的；<unit>是｛second，seconds，minute，minutes，hour，hours，day，days，week，weeks，month，months，year，years｝之一；加上可选的business指示，意味着对于这个期限只有业务时间才应被考虑，如果没有business指示，期限将作为一个绝对的时间段被解释。

14.2 日历配置

文件org/jbpm/calendar/jbpm.business.calendar.properties指定了什么是业务时间，该配置文件可以被定制并且修改后的拷贝可被放在classpath根。

下面是业务时间规范的例子，它在jbpm.business.calendar.properties中被默认配置。

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
