grails - Groovy，Grails；每周为变量添加+1

Question

想象一下，您每周需要召开一次 session ，就需要每周将+1添加到整数“meetingWeek”中。
你怎么做到这一点？

我当时正在考虑使用日期“startDate”和整数“meetingWeek”，
所以

startDate= 2014/04/07
meetingWeek = 3 (We already had 3 meetings for example)

然后:

weekDif = todayDate-startDate
totalWeeks = weekDif + meetingWeek

如果我们在2014/04/14(“todayDate”)，则结果必须为MeetingWeek = 4;在剩余的一周内也必须为4。
如果我们在2014/04 / 21-25，则结果必须为MeetingWeek = 5

因此，在常规情况下，我可以执行以下操作:

use(groovy.time.TimeCategory) {
   def weekDif = todayDate-startDate
   println "days: ${weekDif.days}, Hours: ${weekDif.hours}"
}

我如何获得周数？

Answer 1

忽略我以前的答案。这个应该可以-

import groovy.time.TimeCategory
import java.lang.Math
def dateParser = new java.text.SimpleDateFormat("yyyy/MM/dd")
def startDate = dateParser.parse("2014/04/04").getTime()
def futureDate1 = dateParser.parse("2014/07/04").getTime()
def futureDate2 = dateParser.parse("2015/07/04").getTime()
def meetingSeed = 3
def millisInWeek = 604800000
def futureDate1Weeks = Math.floor((futureDate1 - startDate)/millisInWeek)
def futureDate2Weeks = Math.floor((futureDate2 - startDate)/millisInWeek)

println("Future Date 1 weeks - " + (futureDate1Weeks + meetingSeed))
println("Future Date 2 weeks - " + (futureDate2Weeks + meetingSeed))
